General Description
The MAX1060/MAX1064 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. The devices
operate with a single +5V analog supply and feature a
V
LOGIC
pin that allows them to interface directly with a
+2.7V to +5.5V digital supply.
Power consumption is only 10mW (V
DD
= V
LOGIC
) at a
400ksps max sampling rate. Two software-selectable
power-down modes enable the MAX1060/MAX1064 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 MAX1060 has
eight input channels and the MAX1064 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 MAX1060 is available in a 28-pin QSOP package,
while the MAX1064 comes in a 24-pin QSOP. For pin-
compatible +3V, 10-bit versions, refer to the MAX1061/
MAX1063 data sheet.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
