NTE7061
Integrated Circuit
Dual 5.3W Audio Power Amplifier Circuit
Description:
The NTE7061 is a dual 5.3W (12V, 3
) power amplifier in a 12Lead SIP type package. Dual amplifier
circuits make stereo operation possible using one chip. Low quiescent current makes the NTE7061
ideal for use in battery operated applications such as radio cassette recorders.
