Overview
The AD7512DITE/883B is a dual SPDT analog switch manufactured by Analog Devices Inc. under the MIL-STD-883 qualification standard. It features CMOS technology with protected inputs and provides two independent switches per package. Key electrical parameters include a maximum on-resistance of 100 Ohms, a maximum supply voltage of +/- 15 V, and switching times with a maximum on-time of 1 us and off-time of 1 us. The device operates within a temperature range up to +125 C and is housed in a CDIP-14 ceramic package.
Feature Summary
- Dual single-pole double-throw (SPDT) switch configuration
- MIL-STD-883 qualified for military and aerospace reliability
- CMOS construction with input protection
- Low on-resistance of 100 Ohms maximum
Applications
- Military communication systems requiring high-reliability signal routing
- Aerospace instrumentation for precise analog signal switching
- Harsh environment data acquisition systems
- Defense electronics utilizing dual-channel multiplexing
Procurement Notes
Verify that the specific suffix /883B confirms compliance with MIL-STD-883 testing requirements for your application. Confirm the package type matches your PCB footprint, as ceramic dual in-line packages have distinct mechanical constraints compared to plastic variants. Ensure the supplier provides traceability documentation consistent with defense procurement standards.
Selection Notes
Select this component when dual isolated signal paths are required in a single package. The 100 Ohm on-resistance suits applications where moderate signal loss is acceptable. Verify that the +/- 15 V supply capability aligns with your system's power rails. Consider the thermal performance of the ceramic package if operating near the upper temperature limit.
Part Context
This part belongs to the AD7512 family of CMOS analog switches. The /883B suffix denotes a specific military-grade variant processed according to MIL-STD-883 standards, distinguishing it from commercial or industrial grade versions. It serves as a robust solution for critical switching tasks where failure is not an option.
Replacement Considerations
Publicly confirmed substitutes are not available in the provided source material. Direct replacement requires verifying pin compatibility and ensuring the alternative meets the same MIL-STD-883 qualification level. Cross-reference with other dual SPDT switches only if the military qualification requirement can be waived.
