Overview
The PI3A2268ZMEX is a dual SPDT analog switch manufactured by Diodes Incorporated in a 10-UQFN package. It operates on a single supply voltage ranging from 1.65V to 4.2V. The device features an on-resistance (RON) of 0.45Ω at 4.2V and 0.55Ω at 3.0V, with a maximum channel-to-channel match of 0.25Ω. Dynamic performance includes a 3dB bandwidth of 79MHz at 3.0V and 84MHz at 4.2V, turn-on time of 15ns, and turn-off time of 20ns. Leakage current is limited to 1μA, while charge injection measures 35pC at 3.0V and 50pC at 4.2V.
Feature Summary
- Dual SPDT configuration supporting independent signal routing
- Low on-resistance for minimal signal attenuation
- High isolation and low crosstalk for signal integrity
- Compatible with standard logic control levels
Applications
- Portable equipment requiring low power consumption
- Cellular phones and handheld devices
- Laptop computers and peripherals
- Video and audio signal switching
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors before procurement. Ensure the component meets environmental directives applicable to your region.
Selection Notes
Select this component when a dual SPDT switch with low on-resistance and high bandwidth is required. Verify that the operating voltage range aligns with the system's power supply. Consider the UQFN package size for space-constrained designs. Check thermal requirements and ensure adequate heat dissipation if continuous current limits are approached.
Part Context
The PI3A2268 belongs to Diodes Incorporated's family of small plastic package analog switches. It is designed for applications requiring efficient signal routing in portable electronics. The ZMEX suffix indicates a tape and reel packaging format within the 10-contact Ultra-thin Quad Flat No-Lead (UQFN) housing.
Replacement Considerations
Consult official substitution guides for verified alternatives. Generic replacements may not match the specific on-resistance, bandwidth, or package dimensions. Verify pin compatibility and electrical characteristics before integrating substitute components into existing designs.
