Description

The ADS8863 is a 16-bit, 680-kSPS, true-differential 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. The device supports unipolar, true-differential analog input signals with a differential input swing of –VREFto +VREF. This true-differential analog input structure allows for a common-mode voltage of any value in the range of 0 V to +VREF(when both inputs are within the operating input range of –0.1 V to VREF+ 0.1 V). Device operation is optimized for very low-power operation. Power consumption directly scales with speed. This feature makes the ADS8863 excellent for lower-speed applications.
