Texas Instruments ADS1282
The ADS1282 is an extremely high-performance, single-chip analog-to-digital converter (ADC) with an integrated, low-noise programmable gain amplifier (PGA) and two-channel input multiplexer (mux). The ADS1282 is suitable for the demanding needs of energy exploration and seismic monitoring environments. The converter uses a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator that provides outstanding noise and linearity performance.| Part No. | ADS1282 |

DESCRIPTION
The modulator is used either in conjunction with the on-chip digital filter, or can be bypassed for use with post processing filters. The flexible input MUX provides an additional external input for measurement, as well as internal self-test connections. The PGA features outstanding low noise (5 nV/√Hz) and high input impedance, allowing easy interfacing to geophones and hydrophones over a wide range of gains.
