400ksps, +5V, 8-/4-Channel, 10-Bit ADCs
with +2.5V Reference and Parallel Interface
General Description
Features
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

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.
