MAX4539, 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 self-monitoring applications. These calibration multiplexers (cal-muxes) have precision resistor-dividers to generate accurate voltage ratios from an input reference voltage. The reference ratios include 15/4096 and 4081/4096 of the external reference voltage, accurate to 15 bits, and 1/2V+ and 5/8(V+ - V-), accurate to 8 bits. The external reference voltage as well as ground CAN also be switched to the output. The MAX4539 MAX4540 have enable inputs and address latching. All digital inputs have 0.8V and 2.4V Logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using a 5V or a single +5V supply. Protection Diodes at all inputs provide an ESD rating >2kV.
The MAX4539 MAX4540 operate from a single +2.7V to +12V supply, or from dual supplies of 2.7V to 6V. On-resistance (100 max) is matched between switches to 6 max. Each Switch CAN handle Rail-to-Rail Analog signals. The off leakage current is 0.1nA at TA = +25C and 2nA at TA = +85C.
The MAX4539 MAX4540 are available in small 20-pin DIP, SO, and SSOP packages.
