Overview
The LA7710 is a SECAM (audio IF, electronic volume
control, AF preamplifier) / PAL (quasi-parallel audio IF
circuit) dual system IC that is packaged in a 16-pin DIP
package. The LA7710 is applicable to the SECAM or PAL
system by changing over the AGC system (pin 3 is brought
to open state or grounded).
Functions
IF amplifier.
Detector.
IF AGC (peak AGC, average AGC).
Electronic volume control.
AF preamplifier.
PAL/SECAM switch.
Features
Used as SECAM audio IF circuit by bringing pin 3 to
open state. Also used as PAL quasi-parallel audio IF cir-
cuit by grounding pin 3.
Electronic volume control : 0dB output available.
