GH580 Overview
The GH580 is a single, second order (12 dB/Oct) continuous high pass filter with an adjustable corner frequency (ƒC) from 200 to 8 kHz. Adjustment of ƒC is acplished with a single 100 kΩ potentiometer connected from pin 3 to ground. The bias circuitry is operated from an on chip voltage regulator providing good supply rejection down to 1.1.
