General DescriptionThe ADC121S101,ADC101S101, and ADC081S101are low
power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital
converters that operateat1 MSPS. Each deviceis basedon successive approximation register architecture with inter-
nal track-and-hold. The serial interfaceis compatible with
several standards, suchas SPI™, QSPI™, MICROWIRE™,
and many common DSP serial interfaces.
The ADC121S101/101S101/081S101 uses the supply volt-
ageasa reference. This enablesthe devicesto operate with full-scale input rangeof0to VDD. The conversion rateis
determined from the serial clock (SCLK) speed. These con-
verters offera shutdown mode, which canbe usedto trade
throughput for power consumption. The ADC121S101/
101S101/081S101 are operated witha single supply that
can range from +2.7Vto +5.25V. Normal power consumption
during continuous conversion, usinga +3Vor +5V supply,is mWor10 mW, respectively. The power down feature,
whichis enabledbya chip select (CS) pin, reduces the
power consumptionto under5 µW usinga +5V supply.All
three converters are availableina 6-lead SOT-23 package,
which providesan extremely small footprintfor applications
where spaceisa critical consideration. The ADC081S101is
also availableina 6-lead LLP package. These products are
designedfor operation overthe industrial temperature range −40˚Cto +85˚C, with some parameters specifiedto
+125˚Cfor the ADC121S101.
