Part Number : ADS8887
Function : 18-Bit, 100-kSPS, Serial Interface, microPower, Miniature, True-Differential Input, SAR Analog-to-Digital Converter / Packages: MSOP-10 and SON-10
Manufacturers : Texas Instruments
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 –V ref to +V ref. 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).
