The ADS8685IPWR from Texas Instruments is a 16-bit, 500 kSPS successive-approximation register (SAR) analog-to-digital converter (ADC) with a single input channel. It incorporates a programmable gain amplifier (PGA) and supports both single-ended and pseudo-differential input configurations via a SPI interface.
The device offers software-programmable bipolar input ranges of ±12.288V, ±10.24V, ±6.144V, ±5.12V, and ±2.56V, as well as unipolar ranges from 0V to 12.288V, 0V to 10.24V, 0V to 6.144V, and 0V to 5.12V. It operates from a 4.75V to 5.25V analog supply and a 1.65V to 5.25V digital I/O supply, and includes an on-chip 4.096V reference.
Typical AC performance includes a signal-to-noise ratio (SNR) of 92 dB, total harmonic distortion (THD) of –107 dB, and DC specifications of ±0.4 LSB DNL and ±0.5 LSB INL. Power consumption is 29 mW typical. Additional features include an integrated oscillator, input over-voltage protection up to ±20V, and a multiSPI interface with daisy-chain support.
The device is housed in a 16-TSSOP (0.173", 4.40mm width) surface-mount package and is specified over the extended industrial temperature range of –40°C to +125°C.
