ADC084S021 Datasheet PDF

●The ADC084S021 is a low-power, four-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 ADC084S021 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. It can be configured to accept up to four input signals at inputs IN1 through IN4.

●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 ADC084S021 operates with a single supply that can range from 2.7 V to 5.25 V. Normal power consumption using a 3-V or 5-V 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 3-V supply or 0.35 µW using a 5-V supply.

●The ADC084S021 comes in a 10-pin VSSOP package. Operation over the industrial temperature range of –40°C to 85°C is ensured.
