Overview
The AD7512DIJP is a single-channel analog switch featuring a Single Pole Double Throw (SPDT) configuration housed in a 20-PLCC package. It operates with dual supplies up to ±15V and provides a maximum on-resistance of 100 ohms with a channel-to-channel matching of 1 ohm. The device exhibits typical switching times of 180ns for turn-on and 350ns for turn-off, alongside off-channel capacitances of 8pF and 1pF respectively. Designed for surface mount installation, it supports an operating temperature range from 0°C to 70°C.
Feature Summary
- Single SPDT analog switching circuit
- Low on-resistance with tight channel matching
- Fast switching performance
- Surface mount PLCC packaging
Applications
- Signal routing in data acquisition systems
- Multiplexing applications requiring low distortion
- Industrial control signal switching
- Test and measurement equipment front ends
Procurement Notes
This component is officially listed as obsolete by Analog Devices Inc., with discontinuation notices dating back to October 2011. Availability is restricted to surplus or secondary market channels. Verification of part authenticity and storage history is critical due to the age of remaining stock. Designers should initiate replacement qualification immediately to ensure long-term supply chain stability.
Selection Notes
Select this device when a single SPDT switch is required within a 20-pin PLCC footprint. It is suitable for applications demanding moderate speed and low on-resistance under dual supply conditions. Consider the AD7510 family variants if different pin counts or SPST configurations are needed. Evaluate thermal constraints carefully as the commercial grade version lacks extended temperature ratings.
Part Context
The AD7512DIJP belongs to the AD7510/AD7512 family of CMOS analog switches manufactured by Analog Devices Inc. These devices utilize complementary metal-oxide-semiconductor technology to provide high isolation and low power consumption. The DIJP suffix specifically denotes the industrial/commercial temperature range variant packaged in a 20-lead Plastic Leadless Chip Carrier format.
Replacement Considerations
Public documentation confirms that the AD7510DIKN is a related component within the same discontinued family. Engineers must verify pin compatibility and functional equivalence before substitution. Since the entire family is obsolete, alternative modern solutions from other manufacturers may offer better availability and updated features.
