The ADC081S021CIMF is a 1-channel 8-bit CMOS Analog-to-digital Converter (ADC) with a high-speed serial interface. 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 to 200 kSPS. The converter is based upon 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. It operates with a single supply that can range from 2.7 to 5.25V. The power-down feature reduces the power consumption to as low as 2.6μW using a 5.25V supply.
