ADC124S021
4 Channel, 200 kSPS, 12-Bit A/D Converter
General Description
TheADC124S021 is a low-power, four-channel CMOS 12-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 ADC124S021 is fully speci-
fied 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
, MICROW-
IRE, and many common DSP serial interfaces.
The ADC124S021 operates with a single supply that can
range from +2.7V to +5.25V. Normal power consumption
using a +3V or +5V supply is 2.2 mW and 7.9 mW, respec-
tively. The power-down feature reduces the power consump-
tion to just 0.14 μW using a +3V supply, or 0.32 μW using a
+5V supply.
The ADC124S021 is packaged in a 10-lead MSOP package.
Operation over the industrial temperature range of 40C to
+85C is guaranteed.
