AD811JRZ-REEL

Overview

The AD811JRZ-REEL is a high-speed current feedback video amplifier manufactured by Analog Devices Inc. It features a single channel in an SOIC-8 surface-mount package. Key electrical parameters include a 140 MHz -3 dB bandwidth at unity gain and a 2500 V/µs slew rate. The device operates within a supply voltage range of ±4.5 V to ±18 V, with a typical quiescent current of 16.5 mA. It exhibits low input offset voltage (3 mV max) and low voltage noise density (1.9 nV/√Hz). The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Optimized for broadcast-quality video systems with excellent differential gain and phase accuracy.
• High-speed current feedback architecture providing wide bandwidth and fast settling times.
• Low power consumption suitable for driving back-terminated cables.
• Flexible operation across standard dual supply voltages.

Applications

• Video crosspoint switchers
• Multimedia broadcast systems
• HDTV compatible systems

Procurement Notes

Verify the specific reel quantity and tape-and-reel packaging configuration against the manufacturer's official documentation before procurement. Confirm that the suffix indicates the correct reel format. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and availability status.

Selection Notes

Select this component when designing circuits requiring high-speed video signal processing with minimal distortion. The current feedback topology is ideal for applications demanding fast transient response and wide bandwidth independent of gain settings. Consider the ±4.5 V to ±18 V supply range compatibility with existing system power rails. Evaluate the thermal performance within the specified operating temperature range for long-term reliability.
