NTE1234
Integrated Circuit
FM IF Amplifier
Description:
The NTE1234 is designed for use in FM IF and TV sound IF amp applications. This device contains
3 different stage differential IF amp and a differential peak detector function.
Features:
D Excellent AM Rejection: (AMR = 50db typ.)
D High Sensitivity: (VIN(lim) = 50dBµV typ.)
D Operating Supply Voltage Range: (VCC = 8 to 15V, THD = 0.2% typ.)
D High Recovered Output Voltage: (VOD = 430mV typ. ±75kHz, dev.)
D Low Distortion: (THD = 0.2% typ. 500mV typ. âf = ±75kHz, dev.)
Absolute Maximum Ratings: (TA = +25°C, unless otherwise specified)
