1 / 13 page ADC081S051 Single Channel, 500 kSPS, 8-Bit A/D Converter General Description 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™, QSPI™, 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 µW 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.
