Description
General part information
ADS1287 Series
The ADS1287 device is a low-power, analog-to-digital converter (ADC), with an integrated programmable gain amplifier (PGA) and finite-impulse-response (FIR) digital filter. The ADC is suitable for the demanding needs of seismic equipment requiring precision digitizing with low power consumption.
The ADC features a programmable-gain, high-impedance complementary metal oxide semiconductor (CMOS) amplifier, suitable for direct connection of geophone and hydrophone sensors to the ADC over a wide range of input signals (±2.5 V to ±0.156 V).
The ADC incorporates a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator. The modulator digital output is filtered and decimated by the internal FIR digital filter to yield the ADC conversion result.
