General Description

The MAX1061/MAX1063 low-power, 10-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

pin that allows them to interface directly with a +1.8V to

+3.6V digital supply.

the maximum sampling rate of 250ksps. Two software-

selectable power-down modes enable the MAX1061/

MAX1063 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 MAX1061 has

eight input channels and the MAX1063 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 MAX1061 is available in a 28-pin QSOP package,

while the MAX1063 is available in a 24-pin QSOP. For

pin-compatible +5V, 10-bit versions, refer to the

MAX1060/MAX1064 data sheet.
