Overview
The ADS8866IDRCR is a 16-bit, 100-kSPS (kilosamples per second), single-ended input, analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for low-power, high-accuracy applications and features a wide operating range and excellent AC and DC performance. The ADS8866 operates with a 2.7-V to 3.6-V analog supply voltage (AVDD) and a 1.65-V to 3.6-V digital supply voltage (DVDD), with an external reference voltage range of 2.5 V to 5 V. It is available in VSON-10 and VSSOP-10 packages, making it suitable for space-constrained designs.
