Nice to see you again and wish you a wonderful day. Today I would like to have a discussion on TDA7560 Amplifier. The TDA7560 is a 4 x 51 W quad bridge car radio amplifier. This article mainly introduces circuits, pinout, datasheet and other detailed information about STMicroelectronics TDA7560.
1. Description
The TDA7560 is a class AB audio power amplifier in a Flexiwatt 25 compact designed for high-power vehicle radio. It uses revolutionary BCD (Bipolar/CMOS/DMOS) technology.
The P-Channel/N-Channel output topology allows for a rail-to-rail output voltage swing, which, when combined with high output current and low saturation losses, sets new power standards in the car-radio market, with unsurpassed distortion performance.
2. Features
• Superior output power capability:
– 4 x 51 W/4 Ω max.
– 4 x 45 W/4 Ω EIAJ
– 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %
– 4 x 80 W/2 Ω max.
– 4 x 77 W/2 Ω EIAJ
– 4 x 55 W/2 Ω @ 14.4 V, 1 kHz, 10 %
• Multipower BCD technology
• MOSFET output power stage
• Excellent 2 W driving capability
• Hi-Fi class distortion
• Low output noise
• Standby function
• Mute function
• Automute at min. supply voltage detection
• Low external component count:
– Internally fixed gain (26 dB)
– No external compensation
– No bootstrap capacitors
• On board 0.35 A high side driver
• Protections:
– Output short circuit to GND, to VS, across the load
– Very inductive loads
– Overrating chip temperature with soft thermal limiter
– Output DC offset detection
– Load dump voltage
– Fortuitous open GND
– Reversed battery
– ESD
3. Applications
• High Power Car Radio
