ADS8860 Analog-to-Digital Converter

ADS8860 Analog-to-Digital Converter

Texas Instruments' ADS8860 is a 16-bit, 1 MSPS, single-ended input, analog-to-digital converter (ADC). The device operates with a 2.5 V to 5 V external reference, offering a wide selection of signal ranges without additional input signal scaling. The reference voltage setting is independent of, and can exceed, the analog supply voltage (AVDD).

The device offers an SPI-compatible serial interface that also supports daisy-chain operation for cascading multiple devices. An optional busy-indicator bit makes synchronizing with the digital host easy.
