250ksps, +3V, 8-/4-Channel, 12-Bit ADCs

with +2.5V Reference and Parallel Interface

General Description

Features

The MAX1261/MAX1263 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, byte-wide parallel interface. They operate

Power consumption is only 5.7mW (V

the maximum sampling rate of 250ksps. Two software-

selectable power-down modes enable the MAX1261/

MAX1263 to be shut down between conversions;

accessing the parallel interface returns them to normal

operation. Powering down between conversions can

cut supply current to under 10µA at reduced sampling

rates.

Both devices offer software-configurable analog inputs

for unipolar/bipolar and single-ended/pseudo-differen-

tial operation. In single-ended mode, the MAX1261 has

eight input channels and the MAX1263 has four input

channels (four and two input channels, 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.
