TDA8594 - 4 x 50W power amplifier

General Description

The TDA8594 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology.

It contains four independent amplifiers in BTL configuration.

Key Features

  • 2.1 General.
  • 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  or 2  loads.
  • Speaker fault detection.
  • Independent short-circuit protection per channel.
  • Loss of ground and open VP safe (with 200 m series impedance and a supply decoupling capacitor of 2200 F maximum).
  • All outputs short-circuit proof to ground, supply voltage and across the load.
  • All pins short-circuit.

TDA8594 I2C-bus controlled 4  50 W power amplifier Rev. 5 — 11 June 2013 Product data sheet 1. General description The TDA8594 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. Through the I2C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately. 2. Features and benefits 2.1 General  Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.
