Product details

Description

Control Signal Output Block The AN7259S has linear level meter output (control voltage on Pin2) whose dynamic range is about 60dB wider for change of the input.This control voltage is adjustable by the resistor R4 of Pin1. The adjustable range at R4= 0.8kΩ ~ 10kΩ is more than 30dB in conversion of the input.The polarity of the output voltage from Pin3 is reverse to that of the voltage to be output from Pin2. This output from Pin3 requires insertion of a capacitor (C5 = 4.7µF) since
