12 +12W STEREO AMPLIFIER WITH MUTING

Features: Very few external components No Boucherot cells No bootstrap capacitors High output power No switch on/off noise Very low standby current Fixed gain (20 dB stereo) Programmable turn-on delay Clipping detector Protections: Output AC-DC short circuit to ground and to supply voltage Very inductive loads Loudspeaker protection Overrating chip temperature Load dump voltage Fortuitous open ground ESD Description: The TDA7360 is a new technology class AB Audio Power Amplifier in the Multiwatt® package designed for car radio applications. Thanks to the fully complementary PNP/NPN  output configuration the high power performance  of the TDA7360 is obtained without bootstrap  capacitors. A delayed turn-on mute circuit eliminates audible  on/off noise, and a novel short circuit protection system prevents spurious intervention with highly  inductive loads. The device provides a circuit for the detection of  clipping in the outp...

Stereo 2-W Audio Power Amplifier

General description: The TDA8596 is a quad Bridge Tied Load (BTL) audio power amplifier with symmetrical  inputs, made in BCDMOS technology. It contains four independent amplifier channels in  BTL configuration with complementary (PMOST/NMOST) output stages. Temperature  warning and output signal clipping diagnosis is possible via the I2C-bus and via the  diagnostic pins (DIAG and STB pin). The temperature pre-warning level and clip detection  levels can be programmed via the I2C-bus. The status of each amplifier channel (i.e.  output offset, load connected or not, short circuit condition at the output pins) can be read  out separately . Features Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant) Three hardware-programmable I2C-bus addresses Drives 4 Ω or 2 Ω loads Balanced/symmetrical inputs Speaker fault detection Programmable gain (26 dB and 16 dB) also available in legacy mode Independent short circuit pr...
