ADS8688IDBT Description

Short technical summary and product information.

The Texas Instruments ADS8688IDBT is a 16-bit, 500 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) with eight input channels. It integrates a programmable gain amplifier (PGA), multiplexer, and internal reference, enabling direct connection to sensors with bipolar input ranges up to ±10.24 V. The device supports both single-ended and differential input configurations via an external multiplexer. With a typical power consumption of 65 mW, it is suitable for low-power industrial applications. The ADC features a SPI-compatible interface with daisy-chain support for multiple converters. It is housed in a 38-pin TSSOP package (9.7 mm × 6.4 mm) for surface-mount assembly. Key specifications include a 92 dB SNR, ±0.75 LSB INL, and ±0.5 LSB DNL. The device operates over a -40°C to +125°C temperature range, making it suitable for demanding environments. It is designed for applications such as industrial process control, test and measurement, and data acquisition systems.
