TDA8594 Description
The TDA8594 is a plementary 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.
TDA8594 Key Features
- Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V pliant)
- Three hardware-programmable I2C-bus addresses
- Drives 4 ī or 2 ī loads
- Speaker fault detection
- Independent short-circuit protection per channel
- Loss of ground and open VP safe (with 200 mī series impedance and a supply
- All outputs short-circuit proof to ground, supply voltage and across the load
- All pins short-circuit proof to ground
- Temperature-controlled gain reduction to prevent audio holes at high junction
- Low battery voltage detection
