ADS8331IPW Description

Short technical summary and product information.

The ADS8331IPW is a 16-bit, 500 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates a 4-channel multiplexer, allowing pseudo-differential or single-ended input configurations. The device uses an external reference and communicates via an SPI-compatible serial interface.

 

Key electrical specifications include a typical signal-to-noise ratio (SNR) of 91.5 dB at 5V and 1 kHz input, and a low power consumption of 14.2 mW at 500 kSPS operation. The analog supply voltage range is 2.7V to 5.5V, while the digital I/O supply operates from 1.65V to 5.5V, enabling flexible system integration.

 

The ADC is housed in a 24-pin TSSOP package (0.173", 4.40mm width) with surface mount mounting. It supports daisy-chain mode for multiple device synchronization and includes power-down modes (Deep, Nap, Auto-NAP) to reduce power consumption in idle periods. The operating temperature range is -40°C to 85°C, making it suitable for industrial environments.

 

Typical applications include multi-channel data acquisition, industrial process control, portable instrumentation, and battery-powered monitoring systems.
