ADC122S021CIMM [Texas Instruments]

The ADC122S021 is a low-power, two-channel 12-bit ADC based on a successive-approximation register architecture with an internal track-and-hold circuit. It accepts one or two input signals at IN1 and IN2, operates with a single 2.7V-5.25V supply, and features variable power management. Normal power consumption is 2.2 mW at +3V and 7.9 mW at +5V, reducing to 0.14 µW (shutdown) at +3V and 0.32 µW at +5V. The output serial data is straight binary and compatible with SPI, QSPI, MICROWIRE, and common DSP interfaces. Packaged in an 8-lead VSSSOP package, it operates over the industrial temperature range of -40°C to +85°C.
