High-Voltage, Single 8-to-1/
Dual 4-to-1 Cal-Multiplexers
General Description
The MAX4578/MAX4579 are high-voltage, 8-channel
CMOS multiplexers. The MAX4578 and dual 4-channel
MAX4579 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 volt-
age, accurate to 15 bits, and 1/2(V+) 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
MAX4578/MAX4579 have enable inputs and address
latching. All digital inputs have 0.8V and 2.4V logic
thresholds, ensuring both TTL- and CMOS-logic com-
patibility when using a single +12V or dual ±15V sup-
plies. Protection diodes at all inputs provide >2kV ESD
rating.
The MAX4578/MAX4579 operate from a single +4.5V to
+36V supply or from dual supplies of ±4.5V to ±20V.
On-resistance (350Ω max) is matched between switch-
es to 15Ω max. Each switch can handle Rail-to-Rail
®
analog signals. The off-leakage current is 20pA at T
A
=
+25°C and 1.25nA at T
A
= +85°C.
The MAX4578/MAX4579 are available in small 20-pin
SSOP, SO, and DIP packages.
