The ADC081S021 is a low-power, single channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. It 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 +2.7V to +5.25V. Normal power consumption using a +3.6V or +5.25V supply is 1.3 mW and 7.7 mW, respectively.
The ADC081S021 is an 8-bit successive-approximation register architecture A/D converter featuring an internal track-and-hold circuit. It supports sample rates ranging from 50 ksps to 200 ksps and offers compatibility with SPI, QSPI, MICROWIRE, and common DSP serial interfaces.
The device operates on a single power supply voltage between +2.7V and +5.25V. Power consumption is optimized for low-power applications, drawing as little as 1.3 mW at +3.6V in normal mode or reducing to 2.6 pW in power-down mode using a +5.25V supply. It is available in 6-lead LLP and SOT-23 packages with guaranteed operation over an industrial temperature range of -40°C to +85°C.
