MAX1414

19-2229; Rev 0; 10/01 MAX1407/MAX1408/MAX1409/MAX1414 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 d...
