AD830JR

Overview

The AD830JR is a high-speed video difference amplifier manufactured by Analog Devices Inc. It features an 85 MHz unity gain bandwidth 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 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 SOIC-8 surface-mount format, it supports operation between -40°C and +85°C.

Feature Summary

• Provides wideband differential amplification with high common-mode rejection at video frequencies
• Features fast dynamic performance including high slew rate and short settling time
• Offers flexible operation with high output drive capability and low distortion characteristics

Applications

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

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors. Ensure the ordering part number matches the required pinout and electrical specifications for your design.

Selection Notes

Select this component when high-speed video processing requires precise differential signal handling. Consider its 85 MHz bandwidth and 360 V/μs slew rate for applications demanding rapid signal transitions. Evaluate the SOIC-8 package constraints and power supply requirements relative to system voltage rails.

Part Context

This device belongs to the AD830 series of wideband differencing amplifiers. It is engineered for video frequency applications but remains suitable for various other high-frequency uses. The series emphasizes improvements over discrete difference amplifier approaches, particularly regarding high-frequency common-mode rejection capabilities.

Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference technical parameters such as bandwidth, slew rate, and package dimensions before implementing any substitute components.
