ADS1120QPWRQ1

Analog To Digital Converters (ADC) Overview

The ADS1120QPWRQ1 is a low-power, low-noise 16-bit analog-to-digital converter (ADC) designed for automotive applications. It features a sigma-delta architecture with an integrated programmable gain amplifier (PGA), excitation current sources (iDACs), and an internal oscillator. The device supports 2 or 4 differential/single-ended inputs and communicates via an SPI interface. It operates on analog and digital supply voltages ranging from 2.3 V to 5.5 V. Key specifications include a maximum sampling rate of 2 kS/s, power consumption of 1.4 mW, and an operating temperature range of -40°C to +125°C. It is housed in a 16-TSSOP package and holds AEC-Q100 qualification.
