The MAX1246/MAX1247 12-bit data-acquisition systems  
c omb ine a 4-c ha nne l multip le xe r, hig h-b a nd wid th  
track/hold, and serial interface with high conversion  
speed and low power consumption. The MAX1246 oper-  
ates from a single +2.7V to +3.6V supply; the MAX1247  
operates from a single +2.7V to +5.25V supply. Both  
devices’ analog inputs are software configurable for  
unipolar/bipolar and single-ended/differential operation.  
4-Channel Single-Ended or 2-Channel  
Differential Inputs  
Single-Supply Operation:  
+2.7V to +3.6V (MAX1246)

Internal 2.5V Reference (MAX1246)  
Low Power: 1.2mA (133ksps, 3V supply)  
54µA (1ksps, 3V supply)  
The 4-wire serial interface connects directly to SPI™/  
QSPIand Microwire™ devices without external logic. A  
serial strobe output allows direct connection to TMS320-  
family digital signal processors. The MAX1246/MAX1247  
use either the internal clock or an external serial-interface  
clock to perform successive-approximation analog-to-  
digital conversions.

4-Wire Serial Interface  
Software-Configurable Unipolar or Bipolar Inputs  
16-Pin QSOP Package (same area as 8-pin SO)  
The MAX1246 has an internal 2.5V reference, while the  
MAX1247 requires an external reference. Both parts have  
a re fe re nc e -b uffe r a mp lifie r with a ± 1.5% volta g e -  
adjustment range.  
______________Ord e rin g In fo rm a t io n  
These devices provide a hard-wired SHDN pin and a  
s oftwa re -s e le c ta b le p owe r-d own, a nd c a n b e p ro-  
grammed to automatically shut down at the end of a con-  
version. Accessing the serial interface automatically  
powers up the MAX1246/MAX1247, and the quick turn-on  
time allows them to be shut down between all conver-  
sions. This technique can cut supply current to under  
60µA at reduced sampling rates.
