TDA8945S Mono Bridge Tied Load (BTL) Audio Amplifier
General Description:
The TDA8945S is a single-channel audio power amplifier with an output power of 15 W at an 8Ω load and an 18 V supply. The circuit contains a Bridge Tied Load (BTL) amplifier with an all-NPN output stage and standby/mute logic. The TDA8945S comes in a 9-lead single in-line (SIL) power package.
Features:
- Requires very few external components
- Flexibility in use Quad single-ended or stereo BTL
- High output power
- Low offset voltage at outputs (important for BTL)
- 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
- Identical inputs (inverting and non-inverting)
- Flexible leads
