ADS1271IBPW

The ADS1271IBPW is a 24-bit, delta-sigma analog-to-digital converter (ADC) from Texas Instruments, designed for wide bandwidth applications requiring high precision. It achieves a sampling rate of 105kSPS and provides excellent AC performance with a 51kHz bandwidth, 109dB signal-to-noise ratio (SNR) in high-resolution mode, and -108dB total harmonic distortion (THD). For DC accuracy, it features low offset drift (1.8µV/°C) and gain drift (2ppm/°C). The ADC offers selectable operating modes: high-speed (105kSPS), high-resolution (109dB SNR), and low-power (35mW dissipation). It uses a sigma-delta modulator with a linear phase digital filter and supports both SPI and frame sync serial interfaces, enabling daisy-chain configurations for multichannel systems. The device includes internal offset calibration and a modulator output option. It operates from a 5V analog supply and a 1.8V to 3.3V digital supply, with a temperature range of -40°C to +105°C. The ADS1271IBPW is housed in a 16-pin TSSOP package (4.40mm width) and is supplied in tubes (90 units per tube). Typical applications include vibration and modal analysis, acoustics, dynamic strain gauges, pressure sensors, and test/measurement equipment.
