The ADS8681IPW is a 16-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It integrates a complete analog front-end including a programmable gain amplifier (PGA), a sample-and-hold circuit, and an on-chip 4.096 V reference. The device supports software-programmable bipolar input ranges of ±12.288 V, ±10.24 V, ±6.144 V, ±5.12 V, and ±2.56 V, as well as unipolar ranges from 0 V to 12.288 V.
Key electrical specifications include a typical signal-to-noise ratio (SNR) of 90.5 dB, a total harmonic distortion (THD) of -107 dB, and a typical power consumption of 42 mW. The ADC offers a constant resistive input impedance of at least 1 MΩ and provides input overvoltage protection up to ±20 V. It communicates via an Enhanced SPI or standard SPI interface and supports daisy-chain configurations.
The ADS8681IPW is housed in a 16-pin TSSOP package and operates over an extended industrial temperature range of -40°C to +125°C. It requires a 4.75 V to 5.25 V analog supply and a 1.65 V to 5.25 V digital I/O supply. This device is suitable for precision data acquisition systems in industrial control, test and measurement, and automation applications.
