Texas Instruments ADS8885
The ADS8885 is an 18-bit, 400-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).| Part No. | ADS8885 |
