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 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 +3.
6V or +5.
25V supply is 1.
6 mW and 8.
5 mW, respectively.
The power-down feature reduces the power consumption to as low as 2.
6 µW using a +5.
25V supply.
The ADC081S051 is packaged in 6-lead WSON and SOT-23 packages.
Operation over the industrial temperature range of −40°C to +85°C is ensured.
