The ADC121S021 device is a low-power, singlechannel CMOS 12-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 ADC121S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. 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 ADC121S021 operates with a single supply that can range from 2.7 V to 5.25 V. Normal power consumption using a 3.6-V or 5.25-V supply is 1.5 mW and 7.9 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6 µW using a 5.25-V supply. The ADC121S021 is packaged in 6-pin WSON and SOT-23 packages. Operation over the industrial temperature range of –40°C to 85°C is ensured.
