________________General Description
The MAX4528 low-voltage, CMOS analog IC is config-
ured as a phase-reversal switch and optimized for high-
speed applications such as chopper amplifiers. It
operates from a +2.7V to +12V single supply or from
2.7V to 6V dual supplies.
On-resistance (110
max) is matched between switch-
es to 7
(max). Each switch can handle Rail-to-Rail
analog signals. The leakage current is only 0.5nA at
+25C and 20nA at +85C. All digital inputs have 0.8V
to 2.4V logic thresholds, ensuring both TTL- and
CMOS-logic compatibility.
For higher voltage operation, see the MAX4526/
MAX4527 data sheet.
