Record/Playback Circuit for VCR
Description:
The NTE1710 is an integrated circuit in a 22–Lead DIP type package designed for tape recorder and
VCR audio recording and playback. This device has built–in electronic switches for recording and
playback which include the ones for a noise reduction circuit.
Features:
D Electronic Switches for REC/PLAY Operation Included (Noise–Reduction Switches also Possible)
D Low Noise (Noise Voltage Referred to Input = 0.95µV P.B., R_g = 2.2kΩ, 20Hz to 20kHz)
D Almost All Functions Necessary for REC/PLAY operation and AGC Circuit Included
D Low Current Consumption
D Muting Possible Externally
Absolute Maximum Ratings: (T_A = +25°C unless otherwiser specified)

Note 1. A capacitor of 10µF or over must be used between Pin11 and GND for the purpose of
preventing the AGC circuit oscillation when it is actually used.
