Texas Instruments ADS8688IDBT Data Acquisition IC, 16 bit, 0.5Msps, 38-Pin TSSOP / 1629688

16-Bit Data Acquisition Systems, Texas Instruments. Integrated 16-bit resolution Data Acquisition Systems from Texas Instruments. The devices incorporate 16-bit SAR ADCs to provide a high resolution digital outputs from the analogue front-end at sampling rates of up to 500ksps. The analogue inputs have an impedance of 1 Megohm and are over-voltage protected up to ±20V. Gain is trimmed to ensure high accuracy and DC precision. The serial digital interface is SPI-compatible and supports daisy-chaining of multiple devices. 16-Bit ADC with Integrated Analog Front-End Programmable input ranges: Bipolar ±2.56/5.12/10.24V, Unipolar 5.12/10.24V 5V Analogue Supply, 1.65-5.0V I/O Supply Constant resistive input impedance of 1 MΩ Input overvoltage protection up to ±20 V On-chip 4.096 V low-drift reference voltage 500-ksps aggregate throughput Low power consumption: 65 mW SPI compatible I/F with Daisy-chain capability
