DESCRIPTION

The ADC104S021/ADC104S021Q is a low-power,

four-channel CMOS 10-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

ADC104S021/ADC104S021Q is fully specified over a sample rate range of 50 ksps to 200 ksps. The

converter is based on 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 ADC104S021/ADC104S021Q operates with a single supply, that can range from +2.7V to +5.25V.

Normal power consumption using a +3V or +5V

supply is 1.94 mW and 6.9 mW, respectively. The

power-down feature reduces the power consumption

to just 0.12 μW using a +3V supply, or 0.47 μW using

a +5V supply.

The ADC104S021/ADC104S021Q is packaged in a 10-lead VSSOP package. Operation over the

industrial temperature range of −40°C to +85°C is

ensured.
