2 × 7 W stereo power amplifier
Rev. 01 — 17 March 2006
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 VP
s Thermally protected
s Capability to handle high energy on outputs (VP = 0 V)
s No switch-on/switch-off plop
s Electrostatic discharge protection

12.11 Typical performance characteristics for single-ended application
The test conditions, unless otherwise specified, are: Tamb = 25 °C; VP = 15 V; fi = 1 kHz;
RL = 4 ; single-ended stereo application; fixed gain equals 20 dB; audio band pass from
22 Hz to 22 kHz. All graphs show typical curves.
The graphs as a function of frequency use a band pass of 20 Hz to 80 kHz.
