The ADC084S021 is a low-power, four-channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface. The ADC084S021 is fully specified over a sample rate range of 50 kSPS to 200 kSPS. 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 +2.7V to +5.25V. Normal power consumption using a +3V or +5V 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 +3V supply, or 0.35 µW using a +5V supply. The ADC084S021 is packaged in a 10-lead MSOP package. Operation over the industrial temperature range of −40˚C to +85˚C is guaranteed.
The ADC084S021 is a low‑power, four‑channel CMOS 8‑bit analog‑to‑digital converter with a serial interface. It operates from a single supply voltage of +2.7 V to +5.25 V and supports sample rates from 50 kSPS up to 200 kSPS. The device is offered in a 10‑lead MSOP package and is rated for industrial temperature operation from –40 °C to +85 °C.
