NTE709
Integrated Circuit
TV/FM Sound IF Amplifier
Description:
The NTE709 is a monolithic integrated circuit in a 14–Lead DIP type package providing a multi–stage
wideband amplifier/limiter, an FM quadrature detector, and an emitter–follower audio output stage
and is designed for use in FM receivers or in sound IF of TV receivers.
Features:
D Good Sensitivity
D Excellent AM Rejection
D Low Harmonic Distortion
D Single–Adjustment Timing
D High gain to 50MHz
D 500mV Recovered Audio at 10.7MHz
D Wide Operating Voltage Range

Note 1. The input limiting threshold is the FM input voltage for a recovered audio output which is 3dB
less than the recovered audio for an FM input voltage of 200mVrms.
Note 2. The amplitude modulation rejection is determined by:
AMRdB = 20 log Vout for 100% FM Vin / Vout for 30% AM Vin
