External Resistors

The midrange through high-range gain of the Focus circuit of the M62436FP can be specified using an externally

connected resistor.

The midrange through high-range gain is set by the resistance division value between the 0.22 µ[?] connected to pin 7

and REF. The M62436FP allows the user-specified gain to be set to high or low by switching the Focus position H/L

setting of pin 18. The recommended resistance value settings are listed below.

1. Focus Position “H” Setting

R17+R18

R16+R17+R18

setting possible

2. Focus Position “L” Setting

R18

R16+R17+R18

setting possible

Recommended Setting Values

R16 = 390 , R17 = 200 , R18 = 390

Focus Position "H" = 60%

Focus Position "L" = 40%

Notes 1. The left channel setting pins 7, 8, and 9 correspond to pins 32, 31, and 30.

2. Settings should be made so that R16 + R17 + R18 = 1 kΩ.

The effect (full-range gain) of the Focus circuit of the M62436FP can be reduced using an externally connected resistor.
