AD813ANZ

Overview

The AD813ANZ is a triple low-power inverting feedback video amplifier manufactured by Analog Devices. It features three independent channels within a single package, offering a 3dB bandwidth of 125 MHz and a voltage gain of 70 dB. The device operates on a supply voltage range from 2.4 V to 36 V with a maximum power dissipation of 1.6 W. Key electrical specifications include an input bias current of 1.7 uA, an input offset voltage of 5 mV, a common-mode rejection ratio of 54 dB, and a power supply rejection ratio of 76 dB typical. It is housed in a 14-pin PDIP package and supports operating temperatures from -40°C to +85°C.

Feature Summary

• Triple-channel architecture providing three independent amplifiers in one component
• Internal feedback structure designed for high-speed video signal processing
• Low power consumption suitable for portable and battery-operated systems
• Wide single-supply voltage operation capability

Applications

• Video signal distribution and buffering
• General-purpose amplification circuits
• Portable instrumentation requiring multiple signal paths

Procurement Notes

Verify the specific suffix ANZ indicates lead-free and RoHS compliance when sourcing. Confirm the PDIP-14 through-hole package matches the target PCB footprint. Check manufacturer documentation for any recent product change notices or lifecycle status updates to ensure long-term availability for production designs.

Selection Notes

Select this component when multiple isolated video channels are required without increasing board space. The 125 MHz bandwidth supports standard definition video applications. Ensure the design accommodates the 1.7 uA input bias current and 5 mV offset voltage for precision requirements. Compare against single-channel alternatives if only one path is needed to optimize cost and complexity.

Part Context

This part belongs to the AD813 series of video amplifiers from Analog Devices. It is categorized under general-purpose amplifiers and video amplifier ICs. The device utilizes bipolar technology to achieve its specified speed and power characteristics within the industrial temperature range.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional equivalence with other video amplifiers based solely on pinout compatibility.
