ADS1282IPWG4

ADS1282IPWG4 from Texas Instruments is a Integrated Circuit Ultra-high-resolution 4-kSPS 2-channel delta-sigma ADC with PGA for seismic and energy exploration - Precision ADCs. 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. 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. The digital filter provides selectable data rates from 250 to 4000 samples per second (SPS). The high-pass filter (HPF) features an adjustable corner frequency. On-chip gain and offset scaling registers support system calibration. The synchronization input (SYNC) can be used to synchronize the conversions of multiple ADS1282s. The SYNC input also accepts a clock input for continuous alignment of conversions from an external source. Together, the amplifier, modulator, and filter dissipate 25 mW. The ADS1282 is available in a compact TSSOP-28 package and is fully specified from -40°C to +85°C, with a maximum operating range to +125°C.
