MAX1407CAI-MAX1408CAI-MAX1409CAP
Low-Power / 16-Bit Multichannel DAS with Internal Reference /10-Bit DACs / and RTC
General Description
The MAX1407/MAX1408/MAX1409/MAX1414 are low-
power, general-purpose, multichannel data-acquisition
systems (DAS). These devices are optimized for low-
power applications. All the devices operate from a sin-
gle +2.7V to +3.6V power supply and consume a
maximum of 1.15mA in Run mode and only 2.5µA in
Sleep mode.
The MAX1407/MAX1408/MAX1414 feature a differential
8:1 input multiplexer to the ADC, a programmable
three-state digital output, an output to shutdown an
external power supply, and a data ready output from
the ADC. The MAX1408 has eight auxiliary analog
inputs, while the MAX1407/MAX1414 include four auxil-
iary analog inputs and two 10-bit force/sense DACs.
The MAX1414 features a 50mV trip threshold for the
signal-detect comparator while the others have a 0mV
trip threshold. The MAX1409 is a 20-pin version of the
DAS family with a differential 4:1 input multiplexer to the
ADC, one auxiliary analog input, and one 10-bit
force/sense DAC.
The MAX1407/MAX1408/MAX1414 are available in
space-saving 28-pin SSOP packages, while the
MAX1409 is available in a 20-pin SSOP package.

ABSOLUTE MAXIMUM RATINGS

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.
