Preliminary data sheet
1. General description
The TFA9800 is an integrated class-AB dual output amplifier in a 9-pin DIL-bent-SIL
(DBS9P) power package. The device is primarily developed for CRT and multi-media
applications.
2. Features
s Requires very few external components
s High output power
s Fixed gain
s Good ripple rejection
s Mute/standby switch
s AC and DC short-circuit safe to ground and V_P
s Thermally protected
s Capability to handle high energy on outputs (V_P = 0 V)
s No switch-on/switch-off plop
s Electrostatic discharge protection
