General Description
The MAX1295/MAX1297 low-power, 12-bit analog-to-
digital converters (ADCs) feature a successive-approxi-
mation ADC, automatic power-down, fast wake-up
(2s), 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 MAX1295/MAX1297 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 10A 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 MAX1295 has
six input channels and the MAX1297 has two (three
input channels and one input channel, respectively,
when in pseudo-differential mode).
Excellent dynamic performance and low power, combined
with ease of use and small package size, make these con-
verters ideal for battery-powered and data-acquisition
applications or for other circuits with demanding power-
consumption and space requirements.
The MAX1295/MAX1297 tri-states INT when CS goes high.
Refer to MAX1265/MAX1267 if tri-stating INT is not desired.
The MAX1295 is offered in a 28-pin QSOP package, while
the MAX1297 comes in a 24-pin QSOP. For pin-compati-
ble +5V, 12-bit versions, refer to the MAX1294/MAX1296
data sheet.
