265ksps, +3V, 6-/2-Channel, 12-Bit ADCs

with +2.5V Reference and Parallel Interface

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.
