0.4Ω, Low-Voltage, Single-Supply
SPST Analog Switches in SC70
Detailed Description
The MAX4715/MAX4716 are low on-resistance (RON),
low-voltage, single-pole/single-throw (SPST) analog
switches that operate from a +1.6V to +3.6V single sup-
ply. The MAX4715 is normally open (NO), and the
MAX4716 is normally closed (NC).
When powered from a +3V supply, their 0.4Ω RON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
Logic Inputs
The MAX4715/MAX4716 logic inputs can be driven up
to +3.6V regardless of the supply voltage. For example,
with a +3.3V supply, IN may be driven low to GND and
high to +3.6V. Driving IN Rail-to-Rail® minimizes power
consumption.
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.
