illustrate

The ADC104S021 is a low power, quad CMOS with a high speed serial interface to a 10-bit analog-to-digital converter. Unlike the usual practice of specifying performance at a single sample rate, the ADC104S021 is specified within a sample rate range of 200 ksps that is perfectly over 50 ksps. The converter is a successive approximation register structure based on an internal tracking and holding circuitry. It can be configured to accept four input signals via IN4 to IN1.

THE SERIAL DATA OUTPUT IS BINARY AND COMPATIBLE WITH SEVERAL STANDARD SPI, QSPI,™ MICROWIRE,™ AND SERIAL INTERFACES WITH MANY GENERAL-PURPOSE DSPS.

The ADC104S021 operates with a single supply and can range from +2.7 V to +5.25 V. The power consumption of a normal +3 V or +5 V supply is 1.94 MW and 6.9 MW, respectively. The power-down feature reduces power consumption by only 0.12 microwatts using a +3 V supply, or 0.47 μW using a +5 V supply.

The ADC104S021 is packaged in a 10-lead MSOP package. Operation in the industrial temperature range is guaranteed from -40 °C to +85 °C.
