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

with +2.5V Reference and Parallel Interface

General Description

The MAX1291/MAX1293 low-power, 12-bit analog-to-dig-

ital converters (ADCs) feature a successive-approxima-

tion 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 with a

single +3V analog supply and feature a V

LOGIC

pin that

allows them to interface directly with a +1.8V to +5.5V

digital supply.

Power consumption is only 5.7mW (V

= V

LOGIC

) at the

maximum sampling rate of 250ksps. Two software-selec-

table power-down modes enable the MAX1291/

MAX1293 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 MAX1291 has

eight input channels and the MAX1293 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.

The MAX1291/MAX1293 tri-states

INT

when

goes

high. Refer to MAX1261/MAX1263 if tri-stating

INT

is not

desired.

The MAX1291 is available in a 28-pin QSOP package,

while the MAX1293 is available in a 24-pin QSOP. For

pin-compatible +5V, 12-bit versions, refer to the

MAX1290/MAX1292 data sheet.
