AD8073JRZ

Overview

The AD8073JRZ is a triple current feedback video amplifier manufactured by Analog Devices Inc. It operates on a single 5 V to 12 V supply or dual supplies up to ±6 V, consuming 3.5 mA per amplifier. The device features a 100 MHz bandwidth and 500 V/µs slew rate at a gain of +2. It delivers 30 mA output current with an output swing within 1.3 V of the rails on a 5 V supply. The unit is housed in a 14-lead narrow-body SOIC package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Triple channel configuration integrated into a single 14-lead narrow-body SOIC package for compact designs.
• Optimized for driving back-terminated 150 Ω video loads while maintaining low power consumption.
• Provides high-speed performance including 100 MHz bandwidth and fast settling time suitable for general-purpose applications.

Applications

• Video line driver circuits
• Computer video plug-in boards
• RGB or S-video amplifiers in component systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm that the requested part matches the commercial temperature range requirements. Ensure compatibility with the 14-lead narrow-body SOIC footprint during PCB layout planning.

Selection Notes

Select this component when multiple independent amplification channels are required in a space-constrained environment. It is suitable for cost-sensitive applications needing solid video performance. Consider the 150 Ω load drive capability and single-supply operation flexibility when designing the power stage.

Part Context

This device belongs to the AD8072/AD8073 family of low-cost current feedback amplifiers designed for high-volume consumer electronics. While the AD8072 provides two channels, the AD8073 integrates three amplifiers in one package. Both share similar electrical characteristics optimized for driving standard video impedances efficiently.

Replacement Considerations

The AD8072JRZ serves as a dual-channel alternative within the same product family. Verify pinout compatibility and ensure the application does not require the third amplifier channel provided by the AD8073 variant.
