Overview
The ADS8860IDRCR, produced by Texas Instruments, is a 16-bit, 1-MSPS (mega-samples per second), single-ended input analog-to-digital converter (ADC). This device is designed to operate with a wide range of signal inputs and offers excellent AC and DC performance. It features a 2.5-V to 5-V external reference voltage, which is independent of the analog supply voltage (AVDD), allowing for a wide selection of signal ranges without additional input signal scaling. The ADS8860IDRCR is optimized for low-power operation, making it suitable for various applications requiring high precision and low energy consumption.
