ADS8675IPWR

具有可编程 ±12/±10/±6/±5/±2.5V 输入范围、+5V 电源的 14 位、500kSPS、单通道 SAR ADC 16-TSSOP -40 to 125

The ADS8671 and ADS8675 devices belong to a family of integrated data acquisition system based on a successive approximation SAR analog-to-digital converter ADC. The devices feature a high-speed, high-precision SAR ADC, integrated analog front-end AFE input driver circuit, overvoltage protection circuit up to ±20 V, and an on-chip 4.096-V reference with extremely low temperature drift.

The devices operate on a single 5-V analog supply, but support true bipolar input ranges of ±12.288 V, ±6.144 V, ±10.24 V, ±5.12 V, and ±2.56 V, as well as unipolar input ranges of 0 V to 12.288 V, 0 V to 10.24 V, 0 V to 6.144 V, and 0 V to 5.12 V. The gain and offset errors are accurately trimmed within the specified values for each input range to ensure high dc precision. The input range selection is done by software programming of the device internal registers. The devices offer a high resistive input impedance ≥ 1 MΩ irrespective of the selected input range.

The multiSPI digital interface is backward-compatible to the traditional SPI protocol. Additionally, configurable features simplify interface to a wide range of host controllers.
