AD534TD/883B

Overview

The AD534TD/883B is a monolithic, laser-trimmed four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within a military temperature range of -55°C to +125°C and utilizes a CDIP-20 package. The device features fully differential, high-impedance inputs for X, Y, and Z channels, ensuring flexibility in signal processing applications. It includes an on-chip thin-film resistor network and buried Zener reference for long-term stability. The scale factor is pretrimmed to 10.00 V, with external adjustment capabilities.

Feature Summary

• Monolithic construction with internal laser trimming for precision performance
• Fully differential, high-impedance inputs across all signal channels
• Integrated thin-film resistors and buried Zener reference for stability
• Adjustable scale factor via external resistor configuration

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 the specific suffix /883B indicates compliance with MIL-PRF-38534 Class K requirements for space-qualified die or equivalent military standards. Confirm that the CDIP-20 through-hole package matches the target board layout. Ensure the operating environment remains within the specified -55°C to +125°C range to maintain guaranteed accuracy specifications without external trimming.

Selection Notes

Select this component when high-precision four-quadrant multiplication or division is required in harsh environments. The fully differential input architecture simplifies circuit design by eliminating common-mode noise issues. Consider the adjustable scale factor feature if gain variations beyond the standard 10.00 V setting are necessary for specific system requirements.
