Beschreibung von ADS8862
The ADS8862 is a 16-bit, 680-kSPS, single-ended 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. An optional busy-indicator bit makes synchronizing with the digital host easy.
The device supports unipolar single-ended analog inputs in the 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 ADS8862 excellent for lower-speed applications.
