General Description
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 switch-
es to 6
max. Each switch can handle Rail-to-Rail
analog signals. The off leakage current is 0.1nA at
T
A
= +25°C and 2nA at T
A
= +85°C.
The MAX4539/MAX4540 are available in small 20-pin
DIP, SO, and SSOP packages.
