TPS4100A
FOUR CHANNEL BRIDGED OUTPUT POWER STAGE
Technical Information
Revision 1.1 - November 2005
GENERAL DESCRIPTION
The TPS4100A is a 4 channel bridged (16 power transistors) output power stage. The TPS4100A
accepts 5V CMOS logic signals from a Class-T processor, such as TCD6001, to create a high
fidelity 4-channel audio amplifier. The TPS4100A has been designed specifically for automotive
head unit applications operating on a single 10-26V supply.
