The ADS1285IRHBR is a 32-bit, low-power analog-to-digital converter (ADC) with a programmable gain amplifier (PGA) and a finite impulse response (FIR) filter. This ADC meets the stringent requirements of low noise precision digitization and longer battery run time for seismic monitoring equipment.

The ADS1285IRHBR low-noise PGA allows direct connection to geophones and transformer-coupled hydrophones without the need for external amplifiers.

ADS1285IRHBR This ADC contains a high-resolution delta-sigma modulator and an FIR filter with programmable phase response. A high-pass filter removes DC and low frequency content from a signal. Clock frequency errors are compensated by a sample rate converter with 7ppb resolution.
