DESCRIPTION
The ADC082S101 is a low-power, two-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
ADC082S101 is fully specified over a sample rate range of 500 ksps to 1 Msps. The converter is based on a
successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to
accept one or two input signals at inputs IN1 and IN2.
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 ADC082S101 operates with a single supply that can range from +2.7V to +5.25V. Normal power
consumption using a +3V or +5V supply is 3.2 mW and 9.6 mW, respectively. The power-down feature reduces
the power consumption to just 0.12 µW using a +3V supply, or 0.35 µW using a +5V supply.
The ADC082S101 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of
−40°C to +85°C is guaranteed.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
