General Description
The MAX1091/MAX1093 low-power, 10-bit analog-to-
digital converters (ADCs) feature a successive-approxi-
mation ADC, automatic power-down, fast wake-up
(2s), 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-selec-
table power-down modes enable the MAX1091/
MAX1093 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 10A 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 MAX1091 has
eight input channels and the MAX1093 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 MAX1091/MAX1093 tri-states INT when CS goes
high. Refer to MAX1061/MAX1063 if tri-stating INT is not
desired.
The MAX1091 is available in a 28-pin QSOP package,
while the MAX1093 is available in a 24-pin QSOP. For
pin-compatible +5V, 10-bit versions, refer to the
MAX1090/MAX1092 data sheet.
