DESCRIPTION

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.
