MAX14777
Quad Beyond-the-Rails -15V to +35V
Analog Switch
General Description
The MAX14777 quad SPST switch supports analog
signals above and below the rails with a single 3.0V to
5.5V supply. The device features a selectable -15V/+35V
or -15V/+15V analog signal range for all switches. Each
switch has a separate control input to allow independent
switching, making the device an alternative to opto-relays
in applications that do not need galvanic isolation.
The IC features 10Ω (max) on-resistance, and 9mΩ (typ)
R_ON flatness, along with a low 50nA (max at +85°C) on-
leakage. For maximum signal integrity, the device keeps
this performance over the entire common-mode voltage
range. Each switch can carry up to 60mA (max) of con-
tinuous current in either direction.
The MAX14777 is available in a 20-pin (4mm x 4mm)
TQFN package and is specified over the -40°C to +105°C
temperature range.
