Integrated Circuit
4.2W Dual Audio Power Amplifier
Description:
The NTE1626 is a dual audio power amplifier in a 12−Lead SIP type package designed for use in a
stereo radio cassette. This device has two audio power amplifiers and each of the two provides 4.2W
power at 12V/4Ω.
Features:
D High Output Power:
4.2W/ch (Typ) V_CC = 12V, R_L = 4Ω
5.0W/ch (Typ) V_CC = 12V, R_L = 3Ω
2.2W/ch (Typ) V_CC = 9V, R_L = 4Ω
3.0W/ch (Typ) V_CC = 9V, R_L = 3Ω
D Wide Operating Voltage Range: V_CC = 5 to 16V
D No Shock Noise at Power Supply Switch On & Off
D Soft Clipping Wave Form
D High Ripple Rejection Ratio: R.R.R. = 50dB (Typ)
D Thermal Shutdown Circuit is Built In
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
