ADC081S021 Single Channel, 50 to 200 ksps, 8-Bit A/D Converter
General Description
The ADC081S021 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 ADC081S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The converter is based upon a successiveapproximation register architecture with an internal trackand-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 power-down feature reduces the power consumption to as low as 2.6 µW using a +5.25V supply. The ADC081S021 is packaged in 6-lead LLP and SOT-23 packages. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.
