TDA8592J; TDA8592Q
I2C-bus controlled 4 × 50 W power amplifier
Rev. 01 — 8 June 2004
Preliminary data sheet
1. General description
The TDA8592J; TDA8592Q is a complementary quad BTL audio power amplifier made in
the BCDMOS technology. It contains four independent amplifiers in Bridge Tied Load
(BTL) configuration. Through the I2C-bus the diagnostic information of each amplifier and
speaker can be read separately.
Both front and both rear channel amplifiers can be configured independently in line driver
mode with a gain of 20 dB.
2. Features
s I2C-bus control
s Hardware programmable I2C-bus address
s Can drive a 2 load with a battery voltage of up to 16 V and a 4 load with a battery
voltage of up to 18 V
s DC-load detection: open, short and present
s AC-load (tweeter) detection
s Programmable clip detection: 1 % or 3 %
www.DataSheet4U.coms Programmable thermal protection pre-warning
s Independent short-circuit protection per channel
s Low gain line driver mode (20 dB)
s Loss-of-ground and open VP safe
s All outputs protected from short-circuit to ground, to VP, or across the load
s All pins protected from short-circuit to ground
s Soft thermal clipping to prevent audio holes
s Low battery detection.
