AD834ARZ

Overview

The AD834ARZ is a broadband analog multiplier and frequency divider manufactured by Analog Devices Inc. It operates within an input frequency range of 0 Hz to 500 MHz. The device requires a single supply voltage of 9 V and draws a typical operating current of 35 mA. Electrical specifications include a maximum output current of 4 mA, an output voltage of 400 mV, and a power dissipation rating of 500 mW. It is housed in an 8-SOIC package designed for surface mount installation. The component supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports high-frequency signal processing with an input bandwidth extending up to 500 MHz
• Provides differential output capability for improved signal integrity
• Functions as both a four-quadrant multiplier and a frequency divider

Applications

• Frequency synthesis systems
• Phase-locked loop (PLL) circuits
• Amplitude modulation generation

Procurement Notes

Verify the specific suffix 'ARZ' against the manufacturer's datasheet to confirm the commercial temperature grade (-40°C to +85°C) and tube packaging format. Confirm RoHS compliance status directly with the supplier or official documentation prior to procurement. Availability may be restricted; check current stock levels with authorized distributors before finalizing design-in decisions.

Selection Notes

Select this component when a wide bandwidth up to 500 MHz is required for multiplication or division tasks. Ensure the system can provide a stable 9 V supply, as the device is specified for this voltage level. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the 400 mV output swing meets the input requirements of subsequent stages in the signal chain.

Part Context

The AD834 belongs to the AD834 series of broadband multipliers from Analog Devices. This family includes variants such as the AD834JRZ, which differs primarily in temperature grade and packaging. The AD834ARZ represents the commercial grade version optimized for general-purpose high-speed analog signal processing applications requiring precise mathematical operations on RF signals.

Replacement Considerations

The AD834JRZ is a verified substitute offering identical electrical performance but with a commercial temperature range of 0°C to 70°C. Other family members like the AD835 offer different specifications and should not be assumed interchangeable without detailed parameter comparison.
