Overview
The AD7511DIJN is a monolithic CMOS analog switch featuring four independent single-pole single-throw normally-closed circuits. It operates with dual supplies up to ±15 V or a single supply of +30 V. Key electrical characteristics include an on-state resistance of 100 Ω, channel-to-channel matching of 1 Ω, and charge injection of 30 pC. The device supports switching times of 350 ns (on) and 180 ns (typical off), with leakage current limited to 5 nA.
Feature Summary
- Four independent SPST normally-closed analog switches
- CMOS technology for low power consumption
- Integrated overvoltage protection
- High input impedance
Applications
- Data acquisition systems
- Sample-and-hold circuits
- Automatic test equipment
- Instrumentation
Procurement Notes
Verify component status as obsolete or limited availability may apply. Confirm package type matches the DIP-14 specification. Ensure compliance with RoHS directives if required by the application. Check for military-grade variants such as the DISQ/883B if extended temperature ranges are necessary. Validate supplier authenticity due to potential obsolescence.
Selection Notes
Select this part for applications requiring normally-closed signal paths. Compare against the AD7512 series if normally-open functionality is needed instead. Consider the AD7510 for single-pole single-throw normally-open configurations. Evaluate thermal performance within the specified operating temperature range. Verify pin compatibility with existing PCB layouts.
Part Context
This component belongs to the Analog Devices AD751x family of protected analog switches. It shares architectural similarities with the AD7511DISQ and AD7512DIJN but differs in contact state configuration. The DIJN suffix indicates a plastic DIP-14 package suitable for through-hole mounting.
Replacement Considerations
Public confirmed substitutes include the AD7511DISQ/883B for ceramic DIP packaging and extended temperature ranges. The AD7512DIJN serves as a functional alternative if normally-open contacts are acceptable. Cross-reference pinouts to ensure compatibility before substitution.
