AD835AN

Overview

The AD835AN is a complete four-quadrant, voltage output analog multiplier fabricated on an advanced dielectrically isolated complementary bipolar process. It generates the linear product of X and Y inputs with a -3 dB bandwidth of 250 MHz. The device operates from ±5 V supplies (4.5 V to 5.5 V range) and features high differential input impedance (100 kΩ || 2 pF). It settles to 0.1% of full scale in 20 ns and provides low noise performance at 50 nV/√Hz.

Feature Summary

• Provides simple basic multiplication function W = XY + Z with minimal external components required
• Features very fast settling time to 0.1% of full scale in 20 ns
• Offers DC-coupled voltage output simplifying use
• Maintains high differential input impedance for X, Y, and Z inputs

Applications

• Very fast multiplication, division, squaring
• Wideband modulation and demodulation
• Phase detection and measurement
• Sinusoidal frequency doubling
• Video gain control and keying

Procurement Notes

Verify the specific ordering suffix 'AN' corresponds to the 8-lead Plastic Dual In-Line Package (PDIP) when sourcing. Confirm RoHS compliance status by checking for the 'Z' suffix designation if environmental regulations require it. Ensure supply voltages remain within the specified ±4.5 V to ±5.5 V range for optimal performance.

Selection Notes

Select this component for applications requiring state-of-the-art speed and low noise levels compared to earlier products like the AD534 or AD734. The Z input allows operation with voltage gains up to approximately ×10. Consider the industrial temperature range of −40°C to +85°C for suitability in various environments.

Part Context

The AD835 series includes variants such as the AD835AR in an 8-lead SOIC package. Both packages are specified to operate over the same industrial temperature range. The AD835 represents a monolithic solution designed to be easy to use and cost-effective for signal processing applications previously requiring hybrid or board-level solutions.
