MAX734CSA

Overview

The MAX734CSA is a high-speed, four-quadrant analog multiplier manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides the transfer function W = XY/U with a low-impedance voltage output. The device features a full power bandwidth of 10 MHz and a slew rate of 450 V/µs. Total static error is typically 0.1% of full scale. Distortion is guaranteed to be less than -80 dBc from any input. The X, Y, and Z inputs are fully differential with low capacitance. An internal scaling denominator voltage of 10 V is derived from a buried-Zener reference, though an external denominator can be substituted for division applications.

Feature Summary

• High accuracy with typical total static error of 0.1% of full scale
• High speed performance including 10 MHz full power bandwidth and 450 V/µs slew rate
• Low distortion characteristics guaranteed at less than -80 dBc from any input
• Fully differential low-capacitance X, Y, and Z inputs

Applications

• Analog signal processing requiring precise multiplication
• Frequency mixing and modulation circuits
• Automatic gain control systems
• Direct division mode applications using external denominator substitution

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to potential availability constraints. Confirm package integrity upon receipt. Ensure storage conditions meet specified requirements to maintain electrical performance. Review current datasheet revisions for any updates to pin configurations or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed analog multiplication with low distortion is required. The internal 10 V denominator simplifies design by reducing external component count. Consider the fully differential inputs for noise immunity in sensitive applications. Evaluate the 10 MHz bandwidth against system frequency requirements. Verify that the SOIC-8 package fits the available PCB space constraints.

Part Context

The MAX734 series belongs to Analog Devices' portfolio of precision analog multipliers. It serves as a pin-compatible alternative to industry-standard devices like the AD534. The CSA suffix indicates a commercial temperature range and SOIC-8 package. This family targets applications demanding high linearity and speed in signal processing tasks.

Replacement Considerations

The AD734 is a direct pin-compatible replacement offering identical functionality. Verify that substitute components match the specific package type and temperature rating requirements of the original design.
