TDA8596
I2C-bus controlled 4 à 45 W power ampliï¬er with symmetrical
inputs
Rev. 02 â 8 November 2007
Product data sheet
1. General description
The TDA8596 is a quad Bridge Tied Load (BTL) audio power ampliï¬er with symmetrical
inputs, made in BCDMOS technology. It contains four independent ampliï¬er channels in
BTL conï¬guration 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 ampliï¬er 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 ⦠or 2 ⦠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 m⦠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 Qualiï¬ed in accordance with AEC-Q100
2.2 I2C-bus mode
I DC load detection: open (no load), normal load, line-driver load
I AC load (tweeter) detection
I Detect which load is connected during start-up to allow the system to be conï¬gured to
select the gain accordingly (e.g. line-driver mode or normal mode).
I Independently selectable soft mute of front (channel 1 and channel 3) and rear
channels (channel 2 and channel 4)
