ADC121S051 Datasheet | National Semiconductor

Description The ADC081S051 is a low-power, single channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the ADC081S051 is fully specified over a sample rate range of 200 k SPS to 500 k SPS. The converter is based on a successiveapproximation register architecture with an internal trackand-hold circuit. The output serial data is straight binary, and is patible with several standards, such as SPI™, QSPI™, MICROWIRE, and many mon 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 m W and 10.5 m W, respectively. The power-down feature reduces the power consumption 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.
