AD8073JN

Overview

The AD8073JN is a triple, low-cost 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 provides 30 mA output current and maintains 0.1 dB gain flatness to 10 MHz with differential gain and phase errors of 0.05% and 0.1°, respectively. Packaged in a 14-lead plastic DIP (N-14), it functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Triple channel configuration housed in a compact 14-lead package for space-constrained designs
• Optimized for driving back-terminated 150 Ω video loads with high output current capability
• Low power consumption suitable for battery-operated or thermally sensitive applications
• High-speed performance with fast settling time and wide bandwidth for general-purpose use

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 to confirm the package type and temperature rating. The 'J' designation indicates a commercial operating range of 0°C to 70°C. Confirm that the 'N' suffix corresponds to the 14-lead plastic DIP package required for your board layout. Ensure ESD precautions are observed during handling due to the sensitivity of the internal circuitry.

Selection Notes

Select this component when a cost-effective solution for multi-channel video signal processing is required. It is suitable for applications needing simultaneous amplification of multiple video signals without excessive power draw. Consider the 14-lead DIP package constraints if through-hole mounting is mandatory. Verify that the 150 Ω load optimization aligns with your system's termination requirements.

Part Context

This part belongs to the AD8072/AD8073 family of low-cost video amplifiers. While the AD8072 offers a dual-channel configuration, the AD8073 integrates three amplifiers into a single unit. Both share identical electrical characteristics and performance metrics, differing only in channel count and pinout configuration to accommodate their respective package styles.

Replacement Considerations

Direct replacements include other parts from the AD8072/AD8073 series, such as the AD8073JR in an SOIC package. Cross-referencing with other triple video amplifiers requires verifying matching bandwidth, slew rate, and supply voltage compatibility.
