The ADS1288 is a 32-bit, low-power, analog-to-digital converter (ADC), with a programmable gain amplifier (PGA) and a finite impulse response (FIR) filter. The ADC is designed for the demanding requirements of seismology equipment requiring low power consumption to extend battery run time.
The low-noise PGA extends the ADC dynamic range through gains 1 to 64. The PGA allows direct connection to geophones and transformer-coupled hydrophones without the need of an external amplifier. The optional unity-gain buffer reduces power consumption.
The ADC incorporates a high-resolution, delta-sigma (ΔΣ) modulator and a FIR filter with programmable phase response. The high-pass filter removes dc and low-frequency content from the signal. Clock frequency error is compensated by the sample rate converter with up to 7ppb frequency accuracy.
The ADC supports 3.3V operation to minimize device power consumption. Power consumption is 3mW (typical) in buffer mode operation and 5mW (typical) in PGA mode operation.
The ADC is available in a compact 5mm × 5mm VQFN package and is fully specified over the –40°C to +85°C ambient temperature range.
