Description

The ADC082S021 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 ADC082S021 is fully specified over a sample rate range of 50 kSPS to 200 kSPS. 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™, MICROW- IRE, and many common DSP serial interfaces. The ADC082S021 operates with a single supply that can range from +2.7V to +5.25V. Normal power consumption using a +3V or +5V supply is 1.6 mW and 5.8 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 ADC082S021 is packaged in an 8-lead MSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.
