ADC121S101/ADC101S101/ADC081S101  
1MSPS, 12-/10-/8-Bit A/D Converters in SOT-23 & LLP  
General Description  
Features  
n Variable power management  
The ADC121S101, ADC101S101, and ADC081S101 are low  
power, monolithic CMOS 12-, 10- and 8-bit analog-to-digital  
converters that operate at 1 MSPS. Each device is based on  
a successive approximation register architecture with inter-  
nal track-and-hold. The serial interface is compatible with  
n Packaged in 6-lead SOT-23 (ADC081S101 also  
available in a 6-Lead LLP package)  
n Power supply used as reference  
n Single +2.7V to +5.25V supply operation  
several standards, such as SPI , QSPI , MICROWIRE  
and many common DSP serial interfaces.  
,
n SPI /QSPI /MICROWIRE /DSP compatible  
The ADC121S101/101S101/081S101 uses the supply volt-  
age as a reference. This enables the devices to operate with  
a full-scale input range of 0 to VDD. The conversion rate is  
determined from the serial clock (SCLK) speed. These con-  
verters offer a shutdown mode, which can be used to trade  
throughput for power consumption. The ADC121S101/  
101S101/081S101 are operated with a single supply that  
can range from +2.7V to +5.25V. Normal power consumption  
during continuous conversion, using a +3V or +5V supply, is  
2 mW or 10 mW, respectively. The power down feature,  
which is enabled by a chip select (CS) pin, reduces the  
power consumption to under 5 µW using a +5V supply. All  
three converters are available in a 6-lead SOT-23 package,  
which provides an extremely small footprint for applications  
where space is a critical consideration. The ADC081S101 is  
also available in a 6-lead LLP package. These products are  
designed for operation over the industrial temperature range  
of −40˚C to +85˚C, with some parameters specified to  
+125˚C for the ADC121S101.
