General Description
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.
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.
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.
