PI5A100
Precision, Wide-Bandwidth
Quad SPDT Analog Switch
Features
Description
• Single Supply Operation (+2V to +6V)
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.
• Rail-to-Rail Analog Signal Dynamic Range
• Low On-Resistance (6Ω typ with 5V supply) Minimizes
Distortion and Error Voltages
• On-Resistance Matching Between Channels, 0.4Ω Typ.
• On-Resistance Flatness, <2Ω Typ.
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.
• Low Charge Injection Reduces Glitch Errors, Q = 6pC Typ.
• Replaces Mechanical Relays
ThePI5A100isfullyspecifiedwith+5V,and+3.3V supplies.With
+5V, it guarantees less than 10Ω On-Resistance. On-Resistance
matching between channels is within 2Ω. On-Resistance flatness
is less than 4Ω over the specified range. The PI5A100 guarantees
• High Speed. t , 8ns Typ.
ON
• Low Crosstalk: -100dB @ 10 MHz
• Low Off-Isolation: -57dB @ 10 MHz
• Wide -3dB Bandwidth: 230 MHz
• High-Current Channel Capability: >100mA
• TTL/CMOS Logic Compatible
fast switching speeds (t < 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.
• Low Power Consumption (0.5µW typ.)
• Packaging (Pb-free & Green Available):
-16-pin QSOP (Q)
-16-pin SOIC (W)
