General Description
The MAX1294/MAX1296 low-power, 12-bit analog-to-
digital converters (ADCs) feature a successive-approxi-
mation ADC, automatic power-down, fast wake-up
(2μs), on-chip clock, +2.5V internal reference, and
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 MAX1294/MAX1296 to be shut
down between conversions; accessing the parallel
interface returns them to normal operation. Powering
down between conversions can reduce supply below
10μA 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 MAX1294 has six
input channels and the MAX1296 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 MAX1294 is
offered in a 28-pin QSOP package, while the MAX1296
is available in a 24-pin QSOP. For pin-compatible +3V,
12-bit versions, see the MAX1295/MAX1297.
