Unlike the conventional practice of specifying performance at a single sample rate only, the ADC081S021 is fully specified over a sample rate range of 50 ksps to 200 ksps.
The converter is based upon a successive-approximation register architecture with an internal track-and-hold circuit.
The output serial data is straight binary, and is compatible with several standards, such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.
The ADC081S021 operates with a single supply that can range from 2.
7 V to 5.
25 V.
Normal power consumption using a 3.
6-V or 5.
25-V supply is 1.
3 mW and 7.
7 mW, respectively.
The power-down feature reduces the power consumption to as low as 2.
6 µW using a 5.
25-V supply.
The ADC081S021 is packaged in 6-pin WSON and SOT-23 packages.
Operation over the industrial temperature range of −40°C to 85°C is ensured.
