- Ultra-low power consumption suitable for battery-operated portable devices
Applications
- Cell phones
- PDAs
- Portable instrumentation
- Computer peripherals
- Dual SIM card switching
Procurement Notes
Verify the specific ordering suffix 'ZTAEX' against the manufacturer's official documentation to confirm the package type and tape-and-reel configuration. Ensure that the procurement channel is authorized to guarantee product authenticity and compliance with RoHS directives. Cross-reference the document number DS40939 Rev 3-2 to ensure access to the most current technical specifications and reliability data.
Selection Notes
Select this component when designing circuits requiring dual-channel signal routing with minimal insertion loss. The wide supply voltage range allows flexibility in system power architectures. Verify that the required on-resistance and bandwidth meet the specific signal integrity requirements of the application. Consider the small form factor for space-constrained designs in mobile or handheld electronics.
Part Context
This part belongs to the PI3A3899 family of high-speed analog switches produced by Diodes Incorporated. The ZTAEX designation indicates a 16-pin UQFN package supplied in a tape-and-reel format. It is designed for applications demanding fast switching speeds and low power consumption in portable electronic devices.
Replacement Considerations
Consult the manufacturer's official documentation for verified substitute part numbers. Do not assume functional equivalence with other analog switches without verifying pinout compatibility, electrical characteristics, and package dimensions.
