The ADC081S051 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 200 ksps to 500 ksps and is based on a successive-approximation register architecture with an internal track-and-hold circuit. The output serial data is straight binary and compatible with several standards. The ADC081S051 operates with a single supply ranging from +2.7V to +5.25V. Power consumption ranges from 1.6 mW to 8.5 mW depending on the supply voltage. The power-down feature reduces power consumption to as low as 2.6 µW. The ADC081S051 is available in 6-lead LLP and SOT-23 packages and is suitable for operation over the industrial temperature range of -40°C to +85°C.
