AD633JN

Overview

The AD633JN is a functionally complete four-quadrant analog multiplier manufactured by Analog Devices Inc. in an 8-lead PDIP package. It provides high impedance differential X and Y inputs and a high impedance summing input (Z). The output voltage is scaled by a nominal 10 V reference generated by a buried Zener diode, with the transfer function defined as W = ((X1 - X2) * (Y1 - Y2) / 10V) + Z. The device operates on supply voltages ranging from ±8 V to ±18 V with a quiescent current of 4 mA typical. It features a small signal bandwidth of 1 MHz, a slew rate of 20 V/µs, and a total error within 2% of full scale.

Feature Summary

• Laser-trimmed accuracy and stability ensuring a guaranteed total error within 2% of full scale.
• High impedance differential X and Y inputs minimize signal source loading.
• Complete design requiring no external components for basic operation.
• Accessible high impedance unity-gain summing input allows for output addition or gain adjustment.

Applications

• Multiplication, division, and squaring operations
• Modulation and demodulation circuits
• Voltage-controlled amplifiers and attenuators
• Phase detection applications

Procurement Notes

Verify that the specific component matches the AD633JN designation, which corresponds to the commercial temperature grade operating range of 0°C to 70°C. Confirm the package type is the 8-lead Plastic Dual In-Line Package (PDIP). Ensure the supplier provides documentation confirming the laser calibration status and adherence to the specified electrical characteristics for the J grade variant.

Selection Notes

Select the AD633JN when a cost-effective, monolithic four-quadrant multiplier is required for commercial temperature environments. This part is suitable for applications where simplicity and low external component count are priorities. Consider the industrial grade AD633AN if operation below 0°C is necessary. Verify that the system power supply remains within the ±8 V to ±18 V range to maintain specified performance levels.

Part Context

The AD633 series represents a family of low-cost analog multipliers designed for general-purpose signal processing. The AD633JN specifically denotes the commercial grade version housed in a through-hole PDIP package. It shares core architectural features with other variants like the SOIC packaged AD633JR but differs in thermal characteristics and physical form factor. It is widely utilized in instrumentation and control systems requiring precise analog computation.

Replacement Considerations

For equivalent functionality, consider the AD633JR for surface mount applications or the AD633AN for extended temperature ranges. Cross-reference with legacy parts such as the AD534 if pin compatibility or specific historical design constraints apply, though functional differences may exist.
