PI5A125
Single Wide Bandwidth Analog Switch
Features
Description
• Single-SupplyOperation(+2Vto+6V)
The PI5A125 is a single analog switch designed for single-supply
operation. This high-precision device is ideal for low-distortion
audio, video, signal switching and routing.
• Rail-to-RailAnalogSignalDynamicRange
• LowOn-Resistance(6-Ohmtypicalwith5Vsupply)
Minimizes Distortion and Error Voltages
ThePI5A125isasingle-polesingle-throw(SPST),normallyclosed
(NC) switch. The switch is open when OE is HIGH.
• On-Resistance Flatness, 3-Ohm typical
• LowChargeInjectionReducesGlitchErrors.
Q=4pC(typical)
This switch conducts current equally well in either direction when
on. When off, it blocks voltages up toVCC
.
• Replaces Mechanical Relays
ThePI5A125isfullyspecifiedwith+5V, and+3.3Vsupplies. With
+5V,itguarantees<10-ohmsON-resistance.ON-resistanceflatness
is less than 5-ohms over the specified range. The switch also
guarantees fast switching speeds (tON <20ns).
• High Speed: tON = 10ns typical
• Wide –3dB Bandwidth: 300 MHz (typical)
• High-CurrentChannelCapability:>100mA
• TTL/CMOSLogicCompatible
This product is available in a 5-pin SOT23 plastic package for
operation over the industrial (–40°C to +85°C) temperature range.
• LowPowerConsumption(0.5µWtypical)
• Small outline transistor package minimizes board area

Notes:
1. The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in
this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design
4. ∆R =R max-R min

5. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.
7. Off Isolation = 20log V / V . See Figure 3.
