ADC082S021CIMM
2 Channel, 200 KSPS, 8-Bit A/D Converter
ADC082S021 Channel, 200 KSPS, 8-Bit A/D Converter
General DescriptionThe ADC082S021isa low-power, two-channel CMOS 8-bit
analog-to-digital converter witha high-speed serial interface.
Unlike the conventional practiceof specifying performancea single sample rate only, the ADC082S021is fully speci-
fied overa sample rate rangeof50 kSPSto 200 kSPS. The
converteris basedona successive-approximation register
architecture withan internal track-and-hold circuit.It canbe
configuredto accept oneor two input signalsat inputs IN1
and IN2.
The output serial datais straight binary, andis compatible
with several standards, suchas SPI™, QSPI™, MICROW-
IRE, and many common DSP serial interfaces.
The ADC082S021 operates witha single supply that can
range from +2.7Vto +5.25V. Normal power consumption
usinga +3Vor +5V supplyis 1.6 mW and5.8 mW, respec-
tively. The power-down feature reducesthe power consump-
tionto just 0.12 µW usinga +3V supply,or 0.35 µW usinga
+5V supply.
The ADC082S021is packagedinan 8-lead MSOP package.
Operation overthe industrial temperature rangeof −40˚Cto
+85˚Cis guaranteed.
Features Specified overa rangeof sample rates. Two input channels Variable power management Single power supply with 2.7V- 5.25V range
