Before doing so, verify that you have met the required minimum impedance (speaker load, in Ohms) as specified on your amplifier or its instruction manual. been widely adopted over linear architectures, and within this class differential or bridge-tied load (BTL) topologies offer key advantages over single-ended (SE) topologies. MAX9711ETC+ - Audio Power Amplifier, Bridge Tied Load(BTL), AB, 1 Channel, 3 W, 4.5V to 5.5V, TQFN, 12 Pins (Pack of 20) (MAX9711ETC+) - - Amazon.com The bridge tied load amplifier 26 amplifies the excitation signal, providing enough current flow to drive the resolver 35. A bridge-tied load configuration consists of one amplifier driving one side of a load and another amplifier (with an inverted signal from the first amplifier) driving the other side of the load. 15 W mono Bridge Tied Load (BTL) audio amplifier Rev. Therefor the minimum load in BTL configuration is 4Ω, however, we recommend to use only a BTL configuration with a load of 8Ω or higher. AVENTAGE 11-channel power amplifier; Supports Bridge-Tied Load (BTL) configuration for 2 x front channels The Bridge-Tied-Load technology (mono mode) allows PA-10 being a super high power amplifier to virtually drive any speaker of the market, while the XLR stereo output enables the PA-10 to be configured in series for convenient high quality multi room solutions helped by the automatic stand-by mode based on the audio signal received. If your loudspeaker has an impedance that drops to 5 ohms at some frequency, each half of the bridge will see 2.5 ohms. This is especially useful for high impedance loads. 6 W mono Bridge Tied Load (BTL) audio amplifier Rev. For today’s car amplifiers this is a minimum of 2 ohms when bridged, usually. If each half is rated at 4 ohms, that could well overload the amplifier. The invention discloses a high-integration BTL (bridge-tied load) audio power amplifier. General description The TDA8945S is a single-channel audio power amplifier with an output power of 15 W at an 8 Ω load and an 18 V supply. TDA8946 Datasheet(PDF) 2 Page - NXP Semiconductors: Part No. The Bridge Tied Load (BTL) feature is new for this model and allows ch.3 and ch.4 to be bridged, with your front left and right speakers wired using the live red inputs on both channels (ch.4 is negative and ch.3 is positive). The bridge−tied load (BTL) configuration shown in Figure 6 is often used to obtain higher output powers compared to the SE configuration when all other variables are equal; i.e., load and supply voltage. Known as: Paralleled amplifier, Bridge tied load, Bridge-Tied Load Expand Multiple electronic amplifiers can be connected such that they drive a single floating load (bridge) or a single common load (parallel), to increase… As shown, the bridge tied load amplifier 26 provides a fixed gain, although other variable gain scenarios are contemplated. In a bridge-tied load configuration, the load impedance which each amplifier channel ‘sees’ is half the characteristic impedance of the connected speaker.

The Bridge Tied Load amplifier topology makes it possible to swing the signal to 60Vpp. This gives double the voltage swing across the speaker and therefore 4 times the power for a given power supply voltage - assuming the amplifier can supply enough current. The circuit contains two Bridge Tied Load A push-pull amplifier can be built using amplifier ICs, rather than discretes, as in the traditional class B amp. TDA8946: Description: 2 x 15 W stereo Bridge Tied Load BTL audio amplifier: Download 23 Pages: Scroll/Zoom: 100% : Maker The amplifier circuit is a perfect balance between power consumption and space design. This allows up to 200W claimed output with both channels driven with an 8-ohm or higher load. 2 x 7 W stereo Bridge Tied Load BTL audio amplifier, TDA8944J datasheet, TDA8944J circuit, TDA8944J data sheet : PHILIPS, alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors. Class-D output stages (a) Single-ended (b) Bridge-tied Load III. One necessary component of the Class-D amplifier is a system to detect excessive current through the output stage, and act to prevent damage to the amplifier. The new Yamaha MX-A5200 amp says it can do both - bi-amp and bridge-tied load (BTL). Abstract: This audio bridge-tied load (BTL) amplifier application note describes a unique architecture that minimizes the differential output distortion and noise (THD+N). The MAX9710 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that evaluates the MAX9710 stereo, 3W, bridge-tied load (BTL) audio power amplifier. General description The TDA8944J is a dual-channel audio power amplifier with an output power of 2 ×7 W at an 8 Ω load and a 12 V supply. General description The TDA8943SF is a single-channel audio power amplifier with an output power of 6 W at an 8 Ω load and a 12 V supply. To further enhance power capacity, the MX-A5200 supports a Bridge-Tied Load (BTL) configuration for the front two channels. Figure 6. Preferably, the amplified excitation signal is a 10 kHz sinusoidal voltage of up to 20 volts p—p. 1. The use of two PA -10 will significantly increase the power of your stereo system. From my reading of the manual - it "looks" like bi-amping requires a speaker to have 2 sets of speaker terminals (obviously for bi-amping). Low-voltage systems driving loudspeakers often employ a bridged-amplifier configuration that effectively doubles the voltage swing at the transducer (speaker). It is one of MPS’ products of fully integrated audio amplifiers which dramatically reduce solution size by integrating the following: It means the the amplifier has two outputs per speaker - one inverting and one non-inverting, the speaker being connected between them. The PA -10 is a fully balanced amplifier with a BTL design (Bridge-Tied-Load) that allows the unit to be easily bridged and operate as a mono amplifier, increasing its power rate from 75Watts per channel @ 8Ω stereo to a remarkable 600Watts @ 4Ω mono. 2 x 7 W stereo Bridge Tied Load (BTL) audio amplifier Rev. This allows for quality in both sound fidelity and power to the front speakers. If its not designed for bridging, you can run into all kinds of problems. TDA8943SF6 W mono Bridge Tied Load (BTL) audio amplifierRev. Can someone explain the difference between bi-amp connecting a speaker and bridge-tied load to a speaker? OVERCURRENT DETECTION Audio amplifier integrated circuits are usually required to withstand several fault conditions which can severely stress the amplifier’s power stage [7], such as short-circuits from the amplifier’s outputs to supply or ground voltage, or wrong Class B and Bridge-Tied Load Amplifiers. Whether you refer to it as bridging, a bridge-tied load (BTL) or strapping, the process is the same. actual size total thickness: 4.25 mm PAA-LM4960SQ-02 Integrated Step Up Converter Bridge tied load Very small inductor Up to 24Vpp 22 components 25 x 25 mm The second amplifier inverts the output of the first amp to achieve the bridge tied load (BTL) operation, doubling the voltage swing and slew rate across the load, allowing for bidirectional operation and good voltage swing on the single-ended power supply. The LM48580 already contains two single-ended amps in a bridge-tied load configuration to double its voltage range from 15 Vpp to 30 Vpp. The EV7748DF-00B is the BTL(Bridge Tied Load) configuration evaluation board for the MP7748, a 60W Mono Class D Audio Amplifier.
