GH580 - DATA SHEET
DESCRIPTION
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 accomplished with a single
100 kpotentiometer 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 V.
The two integrated 1nF capacitors have parasitic diodes
connected in parallel. This necessitates that the DC voltage
at pin 6 be greater that 400 mV and less than VB and that pins
8 and 7 be no greater than approximately 400 mV DC.
The GH580 has a dynamic range of approximately 80 dB.
