TDA8596

TDA8596 I2C-bus controlled 4 × 45 W power amplifier with symmetrical inputs Rev. 02 — 8 November 2007 Product data sheet 1. 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. 2. Features 2.1 General I Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant) I Three hardware-programmable I2C-bus addresses I Drives 4 Ω or 2 Ω loads I Balanced/symmetrical inputs I Speaker fault detection I Programmable gain (26 dB and 16 dB) also available in legacy mode I Independent short circuit protection per channel I Loss of ground and loss of VP safe (with 300 mΩ series impedance and a maximum supply decoupling capacitor of 2200 µF) I All outputs are short-circuit proof to ground, supply voltage and across the load I All pins are short circuit proof to ground I Temperature-controlled gain reduction to prevent audio holes at high junction temperatures I Low battery voltage detection I Qualifie...
