AD532JD/+

Overview

The AD532JD is a monolithic, internally trimmed analog multiplier and divider manufactured by Analog Devices. It operates with a rated supply voltage of ±15 V and supports an operating range from ±10 V to ±18 V. The device features differential X and Y inputs with a transfer function of (X1 − X2)(Y1 − Y2)/10 V. It guarantees a maximum multiplying error of ±2% at 25°C and ±2.5% across the commercial temperature range of 0°C to 70°C. Key electrical specifications include a small-signal bandwidth of 1 MHz, a slew rate of 45 V/µs, and a settling time of 1 µs to 2%. The output voltage swing reaches ±13 V, while quiescent supply current is typically 6 mA.

Feature Summary

• Internally laser-trimmed monolithic construction eliminates the need for external trimming resistors or output operational amplifiers.
• Differential X and Y inputs provide high common-mode rejection and flexibility for algebraic computation and transducer instrumentation.
• Capable of four-quadrant multiplication, two-quadrant division, squaring, and square rooting functions within a single chip.

Applications

• Multiplication, division, squaring, and square rooting operations
• Algebraic computation and modulation applications
• Power measurements and trigonometric calculations
• Instrumentation applications utilizing transducer-generated input signals

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and temperature grade. The AD532JD variant corresponds to the commercial temperature range and ceramic DIP packaging. Ensure compatibility with existing designs requiring pin-for-pin replacement of multipliers that previously utilized external trim networks. Confirm RoHS compliance status if required by system specifications.

Selection Notes

Select the AD532JD for applications requiring simplified design through internal trimming and reduced component count. This model is suitable for commercial environments operating between 0°C and 70°C. Consider the AD532S grade if extended temperature operation up to 125°C is necessary. Evaluate the trade-off between the guaranteed ±2% total error and the cost benefits of the monolithic architecture compared to hybrid modular solutions.

Part Context

The AD532 series represents a family of precision analog multipliers designed to replace complex hybrid circuits. The JD designation identifies the commercial grade version housed in a 14-lead side-brazed ceramic dual in-line package. This component integrates high-impedance input amplifiers and a Gilbert cell multiplier core on a single silicon die, offering advantages in size, reliability, and economy over traditional discrete implementations.

Replacement Considerations

The AD532JD serves as a direct pin-for-pin replacement for IC multipliers requiring external trim networks. To simplify connections, ground the X2, Y2, and VOS terminals when unused. Verify that the new application respects the restricted denominator polarity requirements for division mode to prevent positive feedback conditions.
