Texas Instruments ADC081S021
The ADC081S021 device is a low-power, singlechannel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. 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.| Part No. | ADC081S021 |

DESCRIPTION
Unlike the conventional practice of specifying performance at a single sample rate only, the ADC081S021 is fully specified over a sample rate range of 50 ksps to 200 ksps. The ADC081S021 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 1.3 mW and 7.7 mW, respectively. The power-down feature reduces the power consumption to as low as 2.6 µW using a 5.25-V supply. The ADC081S021 is packaged in 6-pin WSON and SOT-23 packages.
