MAX1245  
________________Ge n e ra l De s c rip t io n  
____________________________Fe a t u re s  
The MAX1245 12-bit data-acquisition system combines  
an 8-channel multiplexer, high-bandwidth track/hold, and  
serial interface with high conversion speed and ultra-low  
power consumption. It operates from a single +2.375V to  
+3.3V supply, and its analog inputs are software config-  
urable for unipolar/bipolar and single-ended/differential  
operation.  
♦ Single +2.375V to +3.3V Operation  
♦ 8-Channel Single-Ended or 4-Channel  
Differential Analog Inputs  
♦ Low Power: 0.8mA (100ksps)  
10µA (1ksps)  
1µA (power-down mode)  
The 4-wire serial interface directly connects to SPI™,  
QSPI™, and Microwire™ devices without external logic.  
A s e ria l s trob e outp ut a llows d ire c t c onne c tion to  
TMS320-family digital signal processors. The MAX1245  
works with an external reference, and uses either the  
internal clock or an external serial-interface clock to  
perform successive-approximation analog-to-digital  
conversions.  
♦ Internal Track/Hold, 100kHz Sampling Rate  
♦ SPI/QSPI/Microwire/TMS320-Compatible  
4-Wire Serial Interface  
♦ Software-Configurable Unipolar or Bipolar Inputs  
♦ 20-Pin DIP/SSOP Packages  
________________Ord e rin g In fo rm a t io n  
This device provides 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  
conversion. Accessing the serial interface powers up  
the MAX1245, and the quick turn-on time allows it to be  
shut down between conversions. This technique can  
cut supply current to under 10µA at reduced sampling  
rates.

The MAX1245 is available in a 20-pin DIP package and  
an SSOP that occupies 30% less area than an 8-pin DIP.  
For supply voltages from +2.7V to +5.25V, use the pin-  
compatible MAX147.
