The Texas Instruments ADS1282IPW-1 is an ultra-high-resolution, 4-kSPS, 2-channel delta-sigma Analog-to-Digital Converter (ADC) with an integrated Programmable Gain Amplifier (PGA) designed for seismic and energy exploration applications. It offers a resolution of 31 bits and operates at a maximum sample rate of 4 ksps. The device features a differential input type and is configured in a multiplexed multichannel setup. The interface type is SPI, and it operates within an external reference mode. The operating temperature range is from -40°C to 85°C, with a typical power consumption of 25 mW.
Features of Texas Instruments ADS1282IPW-1
The ADS1282IPW-1 is equipped with a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator that provides outstanding noise and linearity performance, with a Signal-to-Noise Ratio (SNR) of 130 dB at 250 SPS. The ADC modulator can be used with the on-chip digital filter or bypassed for post-processing filters. The flexible input MUX allows for additional external measurements and internal self-test connections. The PGA boasts exceptional low noise (5 nV/√Hz) and high input impedance, facilitating easy interfacing with geophones and hydrophones across a broad range of gains. The digital filter offers selectable data rates from 250 to 4000 samples per second (SPS), with an adjustable corner frequency for the high-pass filter (HPF). On-chip gain and offset scaling registers support system calibration. The synchronization input (SYNC) enables the synchronization of conversions across multiple ADS1282s and can also accept a clock input for continuous alignment of conversions from an external source.
Applications of Texas Instruments ADS1282IPW-1
The ADS1282IPW-1 is particularly suited for demanding environments such as energy exploration and seismic monitoring. Its high resolution, low noise, and programmable gain make it ideal for applications where precise measurements are critical. The device can be used in geophone front-end applications, where it operates with dual ±2.5V analog supplies or a single +5V analog supply. The ADS1282IPW-1 is also designed to withstand the harsh conditions often found in field deployments, with its wide operating temperature range and robust construction.
