250ksps, +3V, 8-/4-Channel, 10-Bit ADCs
with +2.5V Reference and Parallel Interface
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
with a single +3V analog supply and feature a VLOGIC
pin that allows them to interface directly with a +1.8V to
+3.6V digital supply.
Power consumption is only 5.7mW (VDD = VLOGIC) at
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
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
