DESCRIPTION

Variable Power Management  
The ADCS7476, ADCS7477, and ADCS7478 are low  
power, monolithic CMOS 12-, 10- and 8-bit analog-to-  
digital converters that operate at 1 MSPS. The  
ADCS7476/77/78 are drop-in replacements for  
Analog Devices' AD7476/77/78. Each device is based  
on a successive approximation register architecture  
with internal track-and-hold. The serial interface is  
compatible with several standards, such as SPI™,  
QSPI™, MICROWIRE™, and many common DSP  
serial interfaces.  
Packaged in 6-Lead, SOT-23 and WSON  
Power Supply used as Reference  
Single +2.7V to +5.25V Supply Operation  
SPI™/QSPI™/MICROWIRE™/DSP Compatible  
APPLICATIONS  
Automotive Navigation  
FA/ATM Equipment  
The ADCS7476/77/78 uses the supply voltage as a  
reference, enabling 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 converters offer a shutdown mode, which can  
be used to trade throughput for power consumption.  
The ADCS7476/77/78 is 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 and in a 6-lead WSON, both of which  
provide an extremely small footprint for applications
