RC4200AMT

Overview

The RC4200AMT is a four-quadrant analog multiplier manufactured by Fairchild Semiconductor, housed in an 8-SOIC surface-mount package. It provides complete nonlinearity compensation across the full temperature range to ensure high accuracy and low distortion. The device integrates three onboard operational amplifiers specifically designed for use in multiplier logging circuits, offering optimized AC response. Key electrical specifications include a bandwidth of 4 MHz and a signal-to-noise ratio of 94 dB. The component operates with a maximum supply current of 4 mA and supports functions such as multiplication, division, squaring, square rooting, and RMS conversion.

Feature Summary

• Four-quadrant analog multiplication capability with integrated nonlinearity compensation over the full temperature range
• Three onboard frequency-compensated operational amplifiers designed for optimum AC response in logging circuits
• Supports multiple mathematical functions including multiply, divide, square, square root, and RMS-to-DC conversion

Applications

• Low distortion audio modulation circuits
• Automatic gain control (AGC) systems
• Modulation and demodulation applications

Procurement Notes

Verify the specific manufacturer source, as distribution records indicate fulfillment by Rochester Electronics, LLC rather than direct Fairchild Semiconductor shipment. Confirm the RoHS status, which is listed as not applicable in available documentation. Ensure compatibility with the 8-SOIC package dimensions and moisture sensitivity level 3 requirements during handling and assembly processes.

Selection Notes

Select this component when high accuracy and wide bandwidth are required for analog signal processing tasks. The integrated op-amps simplify circuit design for logarithmic applications. Consider the SOIC package for surface-mount assembly needs. Verify that the commercial temperature range and bipolar technology align with the system's environmental and power constraints.

Part Context

The RC4200 series represents a family of analog multipliers originally developed by Raytheon and later produced by Fairchild Semiconductor. Variants include the through-hole RC4200AN and RC4200ANB. The RC4200AMT specifically denotes the surface-mount version in an 8-SOIC package, maintaining the core functionality of the series while adapting to modern PCB mounting standards.

Replacement Considerations

Direct substitutes within the same family include the RC4200AN and RC4200ANB, though these utilize different PDIP packages requiring layout adjustments.
