Detailed Description
The MAX4947 triple DPDT and the MAX4948 hex SPDT
analog switches operate from a single +1.8V to
+5.5V supply. These devices are fully specified for +3V
applications.
The MAX4947/MAX4948 have a guaranteed 4
Ω (typ) on-
resistance and a low 30pF (typ) capacitance that makes
the switch ideal for data switching applications. The
MAX4947 has three logic inputs to control two switches in
pairs and the MAX4948 has one logic control input and
an enable input (
EN) to disable the switches.
Applications Information
Digital Control Inputs
The MAX4947/MAX4948 provide a digital control logic
input, CB_. CB_ controls the position of the switches as
shown in the
Pin Configurations/Truth Tables. Driving
CB_ rail-to-rail minimizes power consumption.
The MAX4948 features an
EN input to turn all switches
on or off. When
EN is driven high, CB is disabled, and
the analog inputs enter a high-impedance state. Drive
EN low to turn the switches on and enable CB.
Analog Signal Levels
The on-resistance of the MAX4947/MAX4948 is very low
and stable as the analog input signals are swept
from ground to VCC (see the Typical Operating
Characteristics). These switches are bidirectional, allow-
ing NO_, NC_, and COM_ to be configured as either
inputs or outputs.
Power-Supply Biasing
Power-supply bypassing improves noise margin and
prevents switching noise to propagate from VCC supply
to other components. A 0.1F capacitor connected
from V+ to GND is adequate for most applications.
Power-Supply Sequencing
CMOS devices require proper power-supply sequencing.
Always apply VCC before the analog signals, especially
if the input signal is not current limited.
