Integrated Circuit
50W to 80W Power Amplifier, Driver
Description:
The NTE7103 is an integrated monolithic circuit in a 14–Lead SIP type package designed for use in
50W to 80W class HiFi audio power amplifier applications. This device consists of an input differential
amplifier, a predriver circuit, a driver circuit, and an over current protection circuit.
