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 single +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 auxiliary 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.
