JM38510/13901BCA

Overview

JM38510/13901BCA is a monolithic laser-trimmed four-quadrant multiplier and divider manufactured by Analog Devices Inc. It features fully differential, high-impedance inputs for X, Y, and Z channels, ensuring flexibility in signal processing applications. The device includes an on-chip thin-film resistor network and buried Zener reference for long-term stability and low temperature coefficients. The scale factor is pretrimmed to a standard value of 10.00 V but can be adjusted externally to values as low as 3 V using an external resistor.

Feature Summary

• Internally trimmed four-quadrant multiplication with guaranteed accuracy without external trimming
• Fully differential, high-impedance operation on all inputs including the Z-input
• Low noise design with excellent supply rejection and long-term stability
• Adjustable scale factor allowing gain up to X100 via external resistor

Applications

• High quality analog signal processing
• Differential ratio and percentage computations
• Algebraic and trigonometric function synthesis
• Accurate voltage controlled oscillators and filters

Procurement Notes

Verify that the specific suffix BCA corresponds to the required military qualification and package type (CDIP14) as defined in the MIL-M-38510 specification. Confirm RoHS compliance status if required for your assembly process, as historical military parts may not meet current environmental directives. Ensure the supplier provides traceability documentation consistent with MIL-PRF-38535 requirements for this class of microcircuit.

Selection Notes

Select this component when high precision analog multiplication or division is required in a monolithic form factor. It is suitable for applications demanding low offset error and high input impedance. Consider the adjustable scale factor feature if system gain requirements vary. Verify thermal management needs as the device operates within a specified military temperature range.

Part Context

The JM38510 series denotes a family of military-grade microcircuits produced under MIL-M-38510 specifications. This specific part is a variant of the AD534 precision multiplier. The 'JM' prefix indicates it is a JANS or similar qualified military version from Analog Devices. It replaces older hybrid multipliers with a cost-effective silicon solution while maintaining high performance standards.

Replacement Considerations

Direct replacements include other JM38510/13901 variants with different suffixes indicating package or temperature grade changes. Generic equivalents like the AD534 commercial grade may be considered if military qualification is not strictly required, though performance specs such as offset drift may differ.
