General description
The TDA1566 is a car audio power amplifier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package. The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identification can be read with I2C-bus. The load identification detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load. The TDA1566 can be configured in a single BTL mode and drive a 1 Ω load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel.

Description
The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a given voltage rail. Additionally, the TDA1400 can be configured as a split supply, bridged amplifier, with the addition of some external components. The TDA1400 is capable of full range operation but the target application is subwoofers due to the high output power capability and single channel operation.
