The AD7985 is a 16-bit, 2.5 MSPS successive approximationanalog-to-digital converter (SAR ADC). It contains a low power,high speed, 16-bit sampling ADC, an internal conversion clock,an internal reference (and buffer), error correction circuits, anda versatile serial interface port. On the rising edge of CNV, theAD7985 samples an analog input, IN+, between 0 V and REFwith respect to a ground sense, IN−. The AD7985 features avery high sampling rate turbo mode (TURBO is high) and areduced power normal mode (TURBO is low) for low powerapplications where the power is scaled with the throughput.
In normal mode (TURBO is low), the SPI-compatible serial interfacealso features the ability, using the SDI input, to daisy-chainseveral ADCs on a single 3-wire bus and provide an optional busyindicator. It is compatible with 1.8 V, 2.5 V, and 2.7 V suppliesusing the separate VIO supply.
The AD7985 is available in a 20-lead LFCSP with operationspecified from −40°C to +85°C.
