Overview
19-2229; Rev 0; 10/01 Low-Power, 16-Bit Multichannel DAS with Internal Reference,10-Bit DACs, and RTC General Description The MAX1407/MAX1408/MAX1409/MAX1414 are lowpower, general-purpose, multichannel data-acquisition systems (DAS).
These devices are optimized for lowpower 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.
