GH580 - Adjustable Analog Highpass Filter

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 kΩ potentiometer connected from pin 3 to ground.

Features

  • 200 to 8 kHz adjustable corner frequency.
  • 12 dB/oct Butterworth filter.
  • low current drain (175 µA typical).
  • two on chip 1 nF capacitors.
  • low noise and distortion.
  • 1.1 to 3.0 VDC operation.

    www.DataSheet4U.com Adjustable Analog Highpass Filter GH580 - DATA SHEET FEATURES • 200 to 8 kHz adjustable corner frequency • 12 dB/oct Butterworth filter • low current drain (175 µA typical) • two on chip 1 nF capacitors • low noise and distortion • 1.1 to 3.0 VDC operation 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 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 V. The two integrated 1 nF capacitors have parasitic diodes connected in parallel.
