General Description
The MAX1266/MAX1268 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 +5V analog supply.
Power consumption is only 10mW at the maximum sam-
pling rate of 420ksps. Two software-selectable power-
down modes enable the MAX1266/MAX1268 to be shut
down between conversions; accessing the parallel
interface returns them to normal operation. Powering
down between conversions can reduce supply below
10A at lower sampling rates.
Both devices offer software-configurable analog inputs for
unipolar/bipolar and single-ended/pseudo-differential
operation. In single-ended mode, the MAX1266 has six
input channels and the MAX1268 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
MAX1266 is offered in a 28-pin QSOP package, while the
MAX1268 is available in a 24-pin QSOP. For pin-compati-
ble +3V, 12-bit versions, see the MAX1265/MAX1267.
