Special Purpose Amplifiers Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than standard distribution channels. Ensure that any sourced units are verified for authenticity and storage history due to the end-of-life status. Cross-reference with replacement options if long-term supply stability is required for new designs.

Special Purpose Amplifiers Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. While it offers integrated octal sampling capabilities, newer alternatives may provide improved performance or availability. Review the original datasheet for pin compatibility if considering direct replacements. Evaluate whether the specific multiplexed input features are necessary or if discrete solutions offer better lifecycle management.

Special Purpose Amplifiers Part Context

The SMP18 belongs to the SMP18 family of octal sample-and-hold amplifiers from Analog Devices. It serves as a specialized linear amplifier solution for analog-to-digital conversion front ends. The FQ suffix denotes the ceramic dual in-line package variant. This series was widely used in industrial and scientific applications requiring simultaneous multi-channel signal conditioning before digitization.
