SMP18FSZ

Special Purpose Amplifiers Overview

The SMP18FSZ is a high-speed sampling and hold integrated circuit manufactured by Analog Devices Inc. It features eight independent channels housed in a 16-SOIC surface-mount package. The device operates on supply voltages ranging from 5 V to 12 V single-ended or ±2.5 V to ±6 V dual-supply configurations. Key electrical specifications include a slew rate of 7 V/µs, an input bias current of 500 nA, and an input offset voltage of 2.5 mV. Power consumption is characterized by a supply current of 6 mA per channel, with an output current capability of 1.2 mA per channel. The component functions reliably within an industrial temperature range of -40°C to +85°C.

Special Purpose Amplifiers Feature Summary

• Integrates eight independent sampling and hold circuits within a single compact package for multi-channel signal acquisition.
• Provides high-speed signal capture capabilities suitable for demanding data conversion front-ends.
• Operates with low power consumption while maintaining precision through low input bias and offset characteristics.

Special Purpose Amplifiers Applications

• Data acquisition systems requiring simultaneous multi-channel signal sampling
• Analog-to-digital converter front-end conditioning
• Industrial process control monitoring

Special Purpose Amplifiers Procurement Notes

Verify the specific suffix 'REEL' when ordering, as it indicates tape-and-reel packaging rather than tube packaging. Confirm that the 16-SOIC footprint matches your PCB design constraints. Ensure supply voltage rails align with the specified 5 V to 12 V single or ±2.5 V to ±6 V dual ranges. Check for any recent product change notices regarding pinout or electrical parameter updates before finalizing procurement.

Special Purpose Amplifiers Selection Notes

Select this component when multiple channels require synchronized sampling within a limited board area. The 16-SOIC package offers a balance between pin count and physical size. Consider the 7 V/µs slew rate against your signal bandwidth requirements. Verify that the 500 nA input bias current meets your source impedance limitations. Compare against other SMP18 variants if through-hole mounting or different channel counts are required.

Special Purpose Amplifiers Part Context

The SMP18 series represents a family of high-performance sampling and hold amplifiers designed for precision analog signal processing. The FSZ variant specifically denotes the surface-mount SOIC package option, distinguishing it from through-hole DIP versions like the SMP18FPZ. This family is engineered for applications demanding fast acquisition times and low droop rates across multiple channels simultaneously.

Special Purpose Amplifiers Replacement Considerations

The SMP18FPZ is listed as a similar alternative but utilizes a 16-PDIP through-hole package. Verify mechanical compatibility and pinout correspondence before substitution. No other direct functional replacements are confirmed in available documentation.
