General Description
The MAX1290/MAX1292 low-power, 12-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. The devices
operate with a single +5V analog supply and feature a
VLOGIC pin that allows them to interface directly with a
+2.7V to +5.5V digital supply.
Power consumption is only 10mW (VDD = VLOGIC) at a
400ksps max sampling rate. Two software-selectable
power-down modes enable the MAX1290/MAX1292 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 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 MAX1290 has
eight input channels and the MAX1292 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 MAX1290/MAX1292 tri-states INT when CS goes
high. Refer to MAX1262/MAX1264 if tri-stating INT is not
desired.
The MAX1290 is available in a 28-pin QSOP package,
while the MAX1292 comes in a 24-pin QSOP. For pin-
compatible +3V, 12-bit versions, refer to the MAX1291/
MAX1293 data sheet.
