MAX1407/MAX1408/MAX1409/MAX1414

Low-Power, 16-Bit Multichannel DAS with

Internal Reference,10-Bit DACs, and RTC

______________________________________________________________________________________ 27

The Data register contains the 16-bit result from the

most recently completed ADC conversion. The data for-

mat is binary for unipolar mode and two’s complement

for bipolar mode. After power-up, the DATA register

contains all zeros.
