400ksps, +5V, 8-/4-Channel, 12-Bit ADCs

with +2.5V Reference and Parallel Interface

General Description

The MAX1262/MAX1264 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. The devices

operate with a single +5V analog supply and feature a

LOGIC

pin that allows them to interface directly with a

+2.7V to +5.5V digital supply.

Power consumption is only 10mW (V

= V

LOGIC

) at a

400ksps max sampling rate. Two software-selectable

power-down modes enable the MAX1262/MAX1264 to

be shut down between conversions; accessing the par-

allel 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 MAX1262 has

eight input channels and the MAX1264 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 MAX1262 is available in a 28-pin QSOP package,

while the MAX1264 comes in a 24-pin QSOP. For pin-

compatible +3V, 12-bit versions, refer to the MAX1261/

MAX1263 data sheet.
