NTE NTE7061

NTE7061
Integrated Circuit
Dual 5.3W Audio Power Amplifier Circuit
Description:
The NTE7061 is a dual 5.3W (12V, 3Ω) power amplifier in a 12–Lead 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.
Features:
D Low Quiescent Current, Low Distortion, Low Noise
D Low Shock Noise from Power ON/OFF Operation
D Minimum External Components
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
