High efficiency enable/disable
I2C bus digital diagnostics (including DC and AC load detection)
Operates both in I2C and non-I2C bus mode
Two selectable I2C bus addresses
Full fault protection
DC offset detection
Four independent short circuit protection
Clipping detector pin with selectable threshold (2 %/10 %)
Standby/mute pin

ESD protection
Description:
The TDA7567PD is a new BCD technology quad bridge power amplifier in PowerSO36 package specially intended for automotive applications.Thanks to the DMOS output stage the TDA7567PD has a very low distortion allowing a clear powerful sound. Among the features, its superior efficiency performance coming from the internal exclusive structure, makes it the most suitable device to simplify the thermal management in high power sets. The dissipated output power under average listening condition is in fact reduced up to 50 % when compared to the level provided by conventional class AB solutions. This device is equipped with a full diagnostics array that communicates the status of each speaker through the I2C bus.The I2C bus can be disabled and the device can be controlled by standby/mute pin.

50 W high performance hi fi amplifier
GENERAL DESCRIPTION
The TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment). The circuit is totally protected, the two output transistors both having thermal and SOAR protection (see Fig.3). The circuit also has a mute function that can be arranged for a period after power-on with a delay time fixed by external components. The device is intended for symmetrical power supplies but an asymmetrical supply may also be used.
Features
- High output power
- Low harmonic distortion
- Low intermodulation distortion
- Low offset voltage
- Good ripple rejection
- Mute/stand-by facilities
- Thermal protection
- Protected against electrostatic discharge
- No switch-on or switch-off clicks
- Very low thermal resistance
- Safe Operating Area (SOAR) protection.
