The ADC081S051 is a low-power, single channel CMOS 8-bit analog-to-digital converter with a high-speed serial in-terface. Unlike the conventional practice of specifying per-formance at a single sample rate only, the ADC081S051 is fully specified over a sample rate range of 200 kSPS to 500 kSPS. The converter is based on 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(TM), QSPI(TM), MICROWIRE, and many common DSP serial interfaces.

The ADC081S051 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 2.9 mW and 10.5 mW, respec-tively.The power-down feature reduces the power consump-tion to as low as 2.6 W using a +5V supply.

The ADC081S051 is packaged in an 6-lead LLP package.

Operation over the industrial temperature range of -40?C to +85?C is guaranteed.
