AD811AN Equivalent & Substitute Parts

Part Overview

The AD811AN is a linear current feedback amplifier manufactured by Analog Devices Inc., designed for video amplification applications. This integrated circuit operates as a single-channel current feedback amplifier in an 8-pin DIP package. The AD811AN is classified as an obsolete product, necessitating identification of active equivalent parts for continued system support and new design implementations. The availability of substitute parts ensures design continuity and procurement flexibility for applications requiring current feedback amplification with specified electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD811AN is determined by electrical and mechanical parameter equivalence. The primary substitution criteria include identical -3dB bandwidth (140 MHz), slew rate (2500 V/µs), supply current (16.5 mA), output current per channel (100 mA), supply voltage range (±4.5V ~ 18V), and package configuration (8-DIP through-hole mounting). The base product number AD811 identifies the core device family, with packaging and product status variations distinguishing individual part numbers within this series.

The AD811ANZ represents an active equivalent that maintains all critical electrical specifications while differing in packaging format (tube versus unspecified packaging for the main part) and product lifecycle status. Both parts are manufactured by Analog Devices Inc. and classified within the linear amplifier category for current feedback applications.

Parameter Comparison

Engineering Selection Recommendations

The AD811ANZ is a direct functional equivalent to the AD811AN, maintaining identical electrical performance across all specified parameters including bandwidth, slew rate, supply current, output current, and supply voltage range. The primary distinction is product lifecycle status: the AD811AN is obsolete while the AD811ANZ is active.

For new designs and ongoing production requirements, the AD811ANZ is the appropriate selection due to its active product status and continued manufacturer support. The AD811ANZ carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for modern applications. Both parts share identical moisture sensitivity classification (MSL 1, Unlimited) and ECCN designation (EAR99), ensuring equivalent handling and export compliance characteristics.

The packaging format difference (tube for AD811ANZ) represents a distribution variation rather than a functional distinction. Both parts utilize identical 8-PDIP through-hole package configuration suitable for PCB assembly in equivalent footprints.

Frequently Asked Questions (FAQ)

Q: Can the AD811ANZ directly replace the AD811AN in existing designs?

A: Yes. The AD811ANZ provides identical electrical specifications across all critical parameters: -3dB bandwidth (140 MHz), slew rate (2500 V/µs), supply current (16.5 mA), output current (100 mA), and supply voltage range (±4.5V ~ 18V). Both parts use the 8-DIP through-hole package with identical pin configuration and footprint.

Q: What is the significance of the product status difference between AD811AN and AD811ANZ?

A: The AD811AN is classified as obsolete, indicating discontinued manufacturing and limited availability. The AD811ANZ is active, ensuring ongoing production, manufacturer support, and availability for procurement. For new designs and production continuity, the active AD811ANZ is the recommended selection.

Q: Are there packaging considerations when substituting AD811AN with AD811ANZ?

A: Both parts are supplied in 8-DIP through-hole packages with identical physical dimensions (0.300", 7.62mm). The AD811ANZ is distributed in tube packaging, while the AD811AN packaging format is unspecified. This represents a distribution method variation with no impact on PCB assembly or electrical performance.

Q: Do the AD811AN and AD811ANZ have different compliance certifications?

A: The AD811ANZ carries explicit RoHS3 compliance and REACH unaffected status certifications. Both parts share identical ECCN (EAR99) and moisture sensitivity level (MSL 1, Unlimited) classifications. The AD811ANZ provides documented regulatory compliance suitable for modern procurement requirements.

Q: What applications are suitable for the AD811AN and AD811ANZ?

A: Both parts are specified for current feedback amplifier applications, including video amplification. The 140 MHz bandwidth and 2500 V/µs slew rate support high-speed signal processing requirements. Identical electrical specifications ensure equivalent performance in all current feedback amplifier circuit topologies.
