265ksps, +3V, 6-/2-Channel, 12-Bit ADCs  
with +2.5V Reference and Parallel Interface  
General Description  
Features  
The MAX1265/MAX1267 low-power, 12-bit analog-to-  
digital converters (ADCs) feature a successive-approxi-  
mation ADC, automatic power-down, fast wake-up  
(2µs), an on-chip clock, +2.5V internal reference, and a  
high-speed 12-bit parallel interface. They operate with  
a single +2.7V to +3.6V analog supply.

o Loftwꢁae-Configuaꢁble Anꢁlog Input Multiplexea  
6-Chꢁnnel Lingle Ended/  
Power consumption is only 5.4mW at the maximum  
sampling rate of 265ksps. Two software-selectable  
power-down modes enable the MAX1265/MAX1267 to  
be shut down between conversions; accessing the par-  
allel interface returns them to normal operation.  
Powering down between conversions can reduce sup-  
ply current below 10µA at lower sampling rates.

o Pꢁaꢁllel 12-Bit Inteafꢁce  
Both devices offer software-configurable analog inputs  
for unipolar/bipolar and single-ended/pseudo-differen-  
tial operation. In single-ended mode, the MAX1265 has  
six input channels and the MAX1267 has two (three  
input channels and one input channel, respectively,  
when in pseudo-differential mode).  
Excellent dynamic performance and low power, com-  
bined with ease of use and small package size, make  
these converters ideal for battery-powered and data-  
acquisition applications or for other circuits with demand-  
ing power-consumption and space requirements. The  
MAX1265 is offered in a 28-pin QSOP package, while the  
MAX1267 comes in a 24-pin QSOP. For pin-compatible  
+5V, 12-bit versions, refer to the MAX1266/MAX1268  
data sheet.
