The ADS8867IDGS is a 16-bit true-differential input Analog-to-digital Converter (ADC) operates with a 2.5 to 5V external reference. It is 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. The device supports unipolar, true-differential analog input signals with a differential input swing of -VREF to +VREF. This true-differential analog input structure allows for a common-mode voltage of any value in the range of 0V to +VREF. Device operation is optimized for very low-power operation. Power consumption directly scales with speed. This feature makes the ADS8867 excellent for lower-speed applications.
