AD835ARZ-REEL

Overview

The AD835ARZ-REEL is a four-quadrant voltage output analog multiplier in an 8-SOIC package. It provides the linear product of X and Y inputs with a Z summing input, following the function W = XY + Z. The device features a 250 MHz small signal bandwidth and a typical settling time of 20 ns to 0.1%. It operates on ±4.5 V to ±5.5 V supplies with a quiescent current of 16 mA. Inputs are differential with high impedance (100 kΩ||2 pF), while the low impedance output can drive loads as low as 25 Ω.

Feature Summary

• Provides complete four-quadrant multiplication with a dedicated summing input for versatile signal processing.
• Features very fast dynamic response with a 250 MHz bandwidth and 20 ns settling time.
• Maintains high differential input impedance to minimize source loading effects.
• Delivers low multiplier noise density suitable for precision applications.

Applications

• Wideband modulation and demodulation
• Phase detection and measurement
• Sinusoidal frequency doubling
• Video gain control and keying

Procurement Notes

Verify that the ordering suffix REEL indicates tape and reel packaging rather than tube. Confirm the RoHS compliant status associated with the Z suffix. Ensure the specific SOIC package dimensions match the design footprint requirements. Check for any recent revision history updates in the datasheet that may affect pinout or electrical characteristics.

Selection Notes

Select this component when high-speed analog multiplication is required within a compact surface-mount form factor. The integrated summing input simplifies circuit topology compared to discrete solutions. Verify that the supply voltage range aligns with the system power rails. Consider the thermal resistance of the SOIC package for heat dissipation in dense layouts.

Part Context

This part belongs to the AD835 family of monolithic multipliers fabricated on a complementary bipolar process. It serves as a high-performance alternative to older hybrid or board-level multiplier solutions. The device integrates essential scaling and biasing internally, reducing external component count.

Replacement Considerations

The AD835ARZ-REEL7 is a compatible variant available in the same package and temperature range. Both parts share identical electrical specifications and pin configurations.
