AD539SD

Overview

The AD539SD is a monolithic analog multiplier and divider integrated circuit manufactured by Analog Devices Inc. It features two-quadrant multiplication and division capabilities with dual signal channels. The device operates within a supply voltage range of ±4.5 V to ±18 V and draws a typical supply current of 10.2 mA. It supports an input bandwidth of up to 60 MHz for the IOUT channel and 5 MHz for the linear control channel. The unit is housed in an 18-SBDIP package and functions reliably across an industrial temperature range from -55 °C to +125 °C.

Feature Summary

• Provides two-quadrant analog multiplication and division functionality on a single chip
• Features dual independent signal channels for high-speed processing applications
• Includes factory calibration to ensure low distortion and high accuracy

Applications

• Automatic gain control (AGC) systems requiring precise amplitude modulation
• Voltage-controlled amplifier (VCA) circuits for dynamic signal adjustment
• Video signal processing tasks involving luminance or chrominance control

Procurement Notes

Verify the specific suffix SD against official Analog Devices documentation to confirm the 18-SBDIP package configuration. Confirm RoHS compliance status as historical data may vary. Check current availability through authorized distributors, as this component may be subject to limited stock or discontinuation notices. Ensure the operating environment matches the specified temperature range before finalizing procurement.

Selection Notes

Select the AD539SD when designing circuits that require high-bandwidth analog multiplication with minimal external calibration. Compare its 60 MHz signal bandwidth against lower-speed alternatives if high-frequency performance is critical. Consider the 18-lead SBDIP package constraints during PCB layout planning. Evaluate power consumption requirements against the 10.2 mA typical supply current draw to ensure thermal management compatibility.

Part Context

This component belongs to the AD539 family of precision analog multipliers designed for demanding signal processing applications. It serves as a specialized amplifier IC capable of performing mathematical operations on analog signals with high linearity. The device integrates multiple functional blocks into a single semiconductor die to reduce system complexity and improve reliability compared to discrete solutions.

Replacement Considerations

The AD539KDZ is a documented alternative offering identical electrical performance in a 16-CDIP package. Verify pinout compatibility between the 18-SBDIP and 16-CDIP packages before substitution. Ensure the replacement part meets the same temperature and voltage specifications required by the original design.
