TDA1552Q 2 x 22 W BTL stereo car radio power amplifier
GENERAL DESCRIPTION
The TDA1552Q is an integrated class-B output amplifier in a 13-lead single-in-line (SIL) plastic power package. The circuit contains 2 x 22 W amplifiers in Bridge Tied Load (BTL) configuration. The device is primarily developed for car radio applications.
Features
- Requires very few external components
- High output power
- Low offset voltage at outputs
- Fixed gain
- Good ripple rejection
- Mute/stand-by switch
- Load dump protection
- AC and DC short-circuit-safe to ground and VP
- Thermally protected
- Reverse polarity safe
- Capability to handle high energy on outputs (VP = 0 V)
- Protected against electrostatic discharge
- No switch-on/switch-off plop
- Low thermal resistance
- Flexible leads.
