The ADC081S101 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 ADC081S101 is fully specified over a sample rate range of 500 ksps to 1 Msps. The converter is based upon 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 ADC081S101 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 2.0 mW and 10.0 mW, respectively. The power-down feature reduces the power consumption to just 2.5 μW using a +5V supply.
The ADC081S101 is packaged in an 6-lead WSON and SOT-23 packages. Operation over the industrial temperature range of ?40°C to +85°C is ensured.
