ADS8887IDGSR Datasheet PDF - TI

●The ADS8887 is an 18-bit, 100-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.

●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 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 ADS8887 excellent for lower-speed applications.
