TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 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.  TDA1566 Audio Amplifier 2x46W / 1x92W

TDA8932 Audio Amplifier 2x15 W

 TDA8932 general description:

The TDA8932 is a high efficiency class-D amplifier with low power dissipation. The typical output power is 2 × 15 W in stereo half-bridge application (RL = 4 Ω) or 1 × 30 W typical in full-bridge application (RL = 8 Ω). Due to the low power dissipation the device can be used without any external heat sink when playing music. If proper cooling via the printed-circuit board is implemented, a continuous output power of 2 × 15 W is feasible. Due to the implementation of thermal foldback, even for high supply voltages and/or lower load impedances, the device remains operating with considerable music output power without the need for an external heat sink. The device has two full-differential inputs driving two independent outputs. It can be used as mono full-bridge configuration (BTL) or as stereo half-bridge configuration (SE).

TDA8932 features:

• Operating voltage from 10 V to 36 V asymmetrical or ±5 V to ±18 V symmetrical
• Mono-bridged tied load (full-bridge) or stereo single-ended (half-bridge) application
• Application without heatsink using thermally enhanced small outline package
• High efficiency and low-power dissipation
• Thermally protected and thermal foldback
• Current limiting to avoid audio holes
• Full short-circuit proof across load and to supply lines (using advanced current protection)
• Switchable internal or external oscillator (master-slave setting)
• No pop noise
• Full-differential inputs

TDA8932 applications:

• Flat panel television sets
• Flat panel monitor sets
• Multimedia systems
• Wireless speakers
• Mini and micro systems
• Home sound sets
