PI5A100
Precision, Wide-Bandwidth
Quad SPDT Analog Switch
Description
The PI5A100 is an improved Quad Single-pole double-throw
(4SPDT) CMOS analog switch designed to operate with a single
+2V to +6V power supply. The EN pin may be used to place all
switches in a high-impedance state. This high precision device
is ideal for low-distortion audio, video, and data switching and
routing.
Each switch conducts current equally well in either direction
when on. In the off state each switch blocks voltages up to the
power-supply rails.
ThePI5A100isfullyspecifiedwith+5V,and+3.3V supplies.With
+5V, it guarantees less than 10 On-Resistance. On-Resistance
matching between channels is within 2. On-Resistance flatness
is less than 4 over the specified range. The PI5A100 guarantees
fast switching speeds (tON < 12ns).
The PI5A100 is available in the narrow-body SOIC and QSOP
packages for operation over the industrial (-40°C to +85°C) tem-
perature range.
