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.
