MAX4540 Low-Voltage / Single 8-to-1 and Dual 4-to-1 Cal-Multiplexers

The MAX4539/MAX4540 low-voltage, CMOS 8-channel (MAX4539) and dual 4-channel (MAX4540) multiplexers are ideal for precision ADC calibration and system selfmonitoring applications. These calibration multiplexers (cal-muxes) have precision resistor-dividers to generate accurate voltage ratios from an .
