Low-Power, 16-Bit Multichannel DAS with

Internal Reference,10-Bit DACs, and RTC

General Description

Features

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.

ꢀ +2.7V to +3.6V Supply Voltage Range in Standby,

Idle, and Run Mode (Down to 1.8V in Sleep Mode)

ꢀ 1.15mA Run Mode Supply Current

ꢀ 2.5µA Sleep Mode Supply Current (Wake-Up, RTC,

and Voltage Monitor Active)

ꢀ Multichannel 16-Bit Sigma-Delta ADC

1.5 ꢀSB (typ) Integral ꢁonlinearity

30Hz or 60Hz Continuous Conversion Rate

Buffered or Unbuffered Mode

Gain of +1/3, +1, or +2V/V

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.
