Detailed Description
The MAX4699/MAX4701 are low-voltage CMOS analog
switches that operate from a single +1.8V to +5.5V
power supply. The MAX4702 requires an additional
logic supply that allows for setting lower logic thresh-
olds. The MAX4699/MAX4701 are double-pole/double-
throw (DPDT) devices. The MAX4702 is a quad
single-pole/double-throw (SPDT) device. These devices
feature a break-before-make switching, fast switching
speeds (with V+ = 5V: tON = 18ns max, tOFF = 9ns max
and with V+ = 3V: tON = 35ns, tOFF = 20) and rail-to-rail
signal handling. A logic input on the MAX4702 allows
for logic thresholds as low as 1.0V.
Applications Information
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in on-
resistance (see
Typical Operating Characteristics). The
switches are bidirectional, so the NO, NC, and COM pins
can be used as either inputs or outputs.
