AD828ARZ

Overview

The AD828ARZ is a dual, high-speed, low-power video amplifier manufactured by Analog Devices Inc. It features a gain-bandwidth product of 100 MHz and a -3dB bandwidth of 130 MHz. The device operates with a supply voltage range from 5 V to 36 V and draws a typical operating supply current of 14 mA per channel. Key electrical specifications include an input bias current of 6.6 uA, an input offset voltage of 2 mV, a common-mode rejection ratio (CMRR) of 82 dB, and a power supply rejection ratio (PSRR) of 80 dB. It is housed in an 8-lead SOIC package.

Feature Summary

• Dual-channel architecture providing two independent high-speed amplification paths within a single component.
• High-speed performance characterized by a 100 MHz gain-bandwidth product for rapid signal processing.
• Low-power operation designed to minimize energy consumption while maintaining high bandwidth capabilities.
• Wide supply voltage tolerance allowing flexibility in various power supply configurations.

Applications

• Video signal processing circuits
• High-speed data acquisition systems
• Sensor signal conditioning

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when dual-channel high-speed amplification is required with moderate power constraints. Ensure the application demands a 100 MHz bandwidth and can accommodate the specified 14 mA quiescent current per channel. Verify that the system power supply falls within the 5 V to 36 V operational range and that the SOIC-8 package fits the board layout constraints.

Part Context

The AD828ARZ belongs to the AD828 series of video amplifiers from Analog Devices. This series is engineered for applications requiring fast transient response and wide bandwidth. The 'ARZ' designation indicates a lead-free, RoHS-compliant variant packaged in an 8-lead Small Outline Integrated Circuit (SOIC) body suitable for surface-mount assembly.

Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. Do not assume functional equivalence based solely on pinout compatibility. Verify that any alternative part meets or exceeds the 100 MHz gain-bandwidth product and 36 V maximum supply voltage requirements.
