SMP18FPZ

Special Purpose Amplifiers Overview

The SMP18FPZ is an obsolete octal sample-and-hold integrated circuit manufactured by Analog Devices Inc. It features eight independent channels housed in a 16-pin plastic dual in-line package (PDIP). Designed for data acquisition systems, this component provides fast acquisition capabilities with a capture time of 3.5 microseconds. It operates within a supply voltage range of 5 V to 12 V or ±2.5 V to ±6 V and supports a working temperature range from -40°C to +85°C.

Special Purpose Amplifiers Feature Summary

• Integrates eight independent sample-and-hold channels into a single monolithic device
• Provides multiplexed input capability for efficient signal routing
• Features fast acquisition speed suitable for high-speed data conversion applications

Special Purpose Amplifiers Applications

• Data acquisition systems requiring multi-channel signal conditioning
• Industrial process control instrumentation
• Test and measurement equipment

Special Purpose Amplifiers Procurement Notes

Verify the obsolete status of the SMP18FPZ before procurement planning. The component was officially declared End-of-Life on July 13, 2016. Current availability is limited to existing stock or surplus markets. Confirm that any available units are genuine Analog Devices products and check for potential shelf-life limitations associated with long-term storage.

Special Purpose Amplifiers Selection Notes

Select the SMP18FSZ variant if surface-mount technology is required instead of through-hole mounting. Consider the SMP18FRUZ-REEL7 for reel-packaged surface-mount solutions. Ensure the application design accounts for the discontinued status of the original part number and validates compatibility with the recommended replacement options provided by the manufacturer.

Special Purpose Amplifiers Part Context

The SMP18FPZ belongs to the SMP18 family of octal sample-and-hold amplifiers. This series is designed to interface directly with analog-to-digital converters in multi-channel environments. The FPZ suffix indicates a 16-pin PDIP package configuration. The component serves as a critical front-end stage for capturing analog signals prior to digitization in precision measurement systems.

Special Purpose Amplifiers Replacement Considerations

The SMP18FSZ is a confirmed similar substitute part number offered by Analog Devices Inc. This alternative maintains the same functional specifications but utilizes a different package type.
