3 Description
The ADS8860 is a 16-bit, 1-MSPS, 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 busyindicator
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 ADS8860 excellent for
lower-speed applications.
