General Description The MAX1402 evaluation system (EV system) is a com- plete, multichannel data-acquisition system consisting of a MAX1402 evaluation kit (EV kit), Maxim 68HC16 micro- controller (µC) module, and USBT0232. The MAX1402 is a low-power, multichannel, serial-output analog to digital converter (ADC).

Calibration Tool The MAX1402 EV kit software can average the mea- surements from the calibration channels and use the measured values to correct the voltage displays. The calibration algorithm assumes that the CALOFF inputs are externally connected together, and that the CALGAIN inputs are externally connected to the refer- ence voltage (VREF).
