AD830ARZ

Overview

The AD830ARZ is a high-speed video differential amplifier manufactured by Analog Devices Inc. It features an 85 MHz gain-bandwidth product and a 360 V/µs slew rate, designed for accurate amplification of fully differential signals while rejecting common-mode noise. The device operates on supply voltages ranging from 8 V to 33 V with a typical quiescent current of 14.5 mA. It provides a minimum output drive of ±50 mA and maintains a 90 dB common-mode rejection ratio. Packaged in an 8-lead SOIC, it supports operation between -40°C and +85°C.

Feature Summary

• Provides high-speed differential amplification with wide common-mode voltage range
• Features low input offset voltage and high common-mode rejection ratio
• Delivers high output drive capability suitable for direct interfacing

Applications

• Differential line receiver circuits
• High-speed level shifting applications
• Differential to single-ended signal conversion

Procurement Notes

Verify the specific package variant against the datasheet, as suffixes like REEL7 indicate tape-and-reel packaging compared to the standard tube configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage requirements align with the specified 8 V to 33 V operational range for reliable performance.

Selection Notes

Select this component when high-frequency differential signal integrity is critical. The 85 MHz bandwidth supports video frequency applications requiring fast settling times. Consider the ±50 mA output drive for driving low-impedance loads without external buffering. Verify thermal management requirements for the SOIC-8 package under maximum operating conditions.

Part Context

This part belongs to the AD830 series of wideband difference amplifiers. It is engineered for video frequencies but applicable to other high-speed analog signal processing tasks. The series emphasizes improved high-frequency common-mode rejection over discrete solutions, offering a compact integrated alternative for precision differential signaling.

Replacement Considerations

The AD830AN is a documented equivalent within the same family. Verify pinout compatibility and electrical parameter alignment before substitution.
