LA7510
No.2866-3/5
Pin Functions
Pin No.
Description
Internal Circuit
1, 2
IF amplifier balanced inputs.
Should be decoupled with a
≥ 0.01μF capacitor.
3
IF AGC filter pin.
The filter capacitor should be 1
μF. A capacitor with good tan δ
temperature characteristics should be used, such as an ALSi
capacitor.
If power supply ripple is high, ripple on the detector output can
be reduced by using the following circuit.
IF AGC

6
Detector output.
The output stage is an emitter-follower. The external resistance
R is required to match impedances with the following 4.5MHz
ceramic band-pass filter. Note that the LA7510 has an internal
330
Ω resister on the output pin.
9
Transistor detector filter pin.
The filter capacitor should be selected for optimum audio
signal-to-noise. Its value should be less than 85pF, since the
4.5MHz signal drops as the capacitance increases, increasing
the picture/sound carrier level ratio and degrading audio S/N
performance.
