The ADC122S051 is a low-power, two-channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface. It operates within a sample rate range of 200 kSPS to 500 kSPS. The converter utilizes a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept one or two input signals. The output serial data is straight binary and compatible with multiple standards such as SPI™, QSPI™, MICROWIRE, and common DSP serial interfaces. The ADC122S051 can be powered by a single supply ranging from +2.7V to +5.25V. Normal power consumption is 3.0 mW with a +3V supply or 10 mW with a +5V supply. The power-down feature reduces power consumption to just 0.14 µW with a +3V supply or 0.32 µW with a +5V supply. The ADC122S051 is packaged in an 8-lead MSOP package and operates over the industrial temperature range of -40˚C to +85˚C.
