NTE7051
Integrated Circuit
1W BTL Mono Audio Amplifier
Description:
The NTE7051 is a mono output amplifier in a 8–Lead DIP style plastic package designed for use in
battery–fed portable audio applications, such as tape recorders and radios.
This device uses the Bridge–Tied–Load principle (BTL) which can deliver an output power of 1.2W
(THD = 10%) into an 8Ω load with a power supply of 6V. The load can be short–circuited at each signal
excursion.
Features:
D No External Components
D No Switch–On or Switch–Off Clicks
D Good Overall Stability
D Low Power Consumption
D No External Heatsink Required
D Short–Circuit Proof
