AD813ARZ-14-REEL7

Overview

The AD813ARZ-14-REEL7 is a triple low-power, internally feedback video amplifier manufactured by Analog Devices Inc. It features three independent channels within an SOIC-14 package, designed for high-speed signal processing in video and data applications. Key electrical specifications include a -3 dB bandwidth of 125 MHz per channel and a slew rate of 100 V/µs. The device operates on supply voltages ranging from 2.4 V to 36 V, with a maximum power dissipation of 1 W. It exhibits an input offset voltage of 5 mV, input bias current of 1.7 µA, and a common-mode rejection ratio (CMRR) of 54 dB. The output type is rail-to-rail, supporting operation across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Triple-channel architecture providing three independent internally feedback amplifiers in a single compact package.
• Rail-to-rail output capability allowing full dynamic range utilization across the specified supply voltage range.
• Internal feedback structure simplifies external component requirements while maintaining high speed and stability.
• Wide single-supply voltage compatibility ranging from 2.4 V to 36 V for flexible system integration.

Applications

• Video signal buffering and distribution in multi-channel display systems
• General-purpose amplification for analog signal conditioning circuits
• High-speed data acquisition front-end stages requiring multiple isolated channels

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging upon order confirmation. Ensure the SOIC-14 footprint matches the target PCB design. Confirm the industrial temperature grade (-40°C to +85°C) aligns with environmental requirements. Cross-reference the manufacturer part number AD813ARZ-14-REEL7 with official Analog Devices documentation to validate revision status before finalizing procurement.

Selection Notes

Select this component when a design requires three independent high-speed amplifiers with rail-to-rail outputs in a space-constrained layout. It is suitable for applications needing moderate bandwidth (125 MHz) and wide supply voltage flexibility. Consider alternative packages if higher pin counts or different thermal profiles are required. Evaluate the 1.7 µA input bias current against source impedance limitations to ensure acceptable offset errors in precision applications.

Part Context

This part belongs to the AD813 series of video amplifiers from Analog Devices, characterized by internal feedback loops that reduce external component count. The AD813 family is engineered for cost-effective video and general-purpose amplification tasks. The -14 variant specifically denotes the 14-lead SOIC package configuration, distinguishing it from other pinout options within the same functional family.

Replacement Considerations

Direct replacements may include other triple video amplifiers from Analog Devices such as the AD813AR-14. Verify pin compatibility and electrical parameters like bandwidth and slew rate when substituting with generic triple op-amps. Ensure any alternative maintains the rail-to-rail output characteristic and similar supply voltage ranges.
