PI5A127
Dual, Wide Bandwidth Analog Switches
Features
Description
• Single-Supply Operation (+2V to +6V)
• Rail-to-Rail Analog Signal Dynamic Range
• Low On-Resistance (7.2-ohm with 5V supply)
Minimizes Distortion and Error Voltages
• On-Resistance Flatness, 3-ohm typ.
• Low Charge Injection Reduces Glitch Errors. Q = 1.6pC typ.
• High Speed. tON = 7ns typ.
• Wide –3dB Bandwidth: 326 MHz
• High-Current Channel Capability: >100mA
• TTL/CMOS Logic Compatible
• Low Power Consumption (5μW typ.)
• Packaging (Pb-free & Green Available)
— 8-pin, 118 mil plastic MSOP (U)
The PI5A127 is a dual SPST (single-pole single-throw)
analog switches designed for single supply operation.
These high-precision devices are ideal for low-distortion audio,
video, signal switching and routing.
The PI5A127 is a normally closed (NC) switch.
Each switch conducts current equally well in either direction
when on. When off, they block voltages up to V+.
These switches are fully specified with +5V and +3.3V supplies.
With +5V, they guarantee <10 -ohm ON-resistance. On-resistance
matching between channels is within 2-ohm. On-resistance flatness
is less than 5-ohm over the specified range. These switches also
guarantee fast switching speeds (tON < 20ns).
These products are available in 8-pin SOIC and MSOP plastic
packages for operation over the industrial temperature range
(–40oC to +85oC).
