AD810AN Equivalent & Substitute Parts

Part Overview

The AD810AN is a linear current feedback amplifier manufactured by Analog Devices Inc., housed in an 8-DIP through-hole package. This integrated circuit functions as a video amplifier with a single feedback circuit, delivering 80 MHz bandwidth and 1000V/µs slew rate. The AD810AN is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support, redesigns, and new production applications. Substitute parts must maintain functional compatibility within the specified electrical and mechanical parameters while accommodating the obsolete status of the original component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD810AN are categorized based on functional compatibility and electrical parameter alignment. The primary substitution criterion is the maintenance of current feedback amplifier topology with compatible bandwidth, slew rate, supply voltage range, and 8-DIP package configuration.

Direct Substitutes maintain identical electrical specifications and are sourced from the same manufacturer base product line:

• AD810ANZ: Active product status with identical electrical parameters and packaging

Similar Substitutes operate within the same amplifier category but with variations in specific electrical characteristics:

• LT1228CN8#PBF and LT1228IN8#PBF: Current feedback amplifiers with higher bandwidth (100 MHz) and slew rate (3500V/µs), compatible supply voltage ranges, and identical packaging
• LT1252CN8#PBF: Current feedback video amplifier with significantly higher bandwidth (282 MHz) and lower slew rate (125V/µs), compatible supply voltage ranges, and identical packaging
• LT1122CCN8#PBF and LT1122DCN8#PBF: J-FET amplifiers with lower bandwidth (13 MHz) and slew rate (75V/µs), compatible supply voltage ranges, and identical packaging

All substitute parts share the 8-DIP through-hole package, single circuit configuration, and MSL 1 rating. Substitution suitability depends on application-specific bandwidth and slew rate requirements.

Parameter Comparison

Engineering Selection Recommendations

AD810ANZ is the primary direct substitute for AD810AN. Both parts maintain identical electrical specifications, including 80 MHz bandwidth, 1000V/µs slew rate, and supply voltage ranges. AD810ANZ holds active product status and carries ROHS3 compliance certification, making it suitable for new designs and production continuity. The transition from AD810AN (tube packaging) to AD810ANZ (tube packaging) requires no circuit redesign.

LT1228CN8#PBF and LT1228IN8#PBF serve as functional substitutes for applications requiring higher bandwidth (100 MHz) and slew rate (3500V/µs) performance. Both maintain current feedback topology and 8-DIP packaging. LT1228IN8#PBF provides higher output current capability (125 mA) compared to the AD810AN (60 mA). Both parts are active and ROHS3 compliant. Operating temperature ranges differ: LT1228CN8#PBF operates 0°C to 70°C, while LT1228IN8#PBF operates -40°C to 85°C.

LT1252CN8#PBF is suitable for applications requiring significantly higher bandwidth (282 MHz) with reduced slew rate (125V/µs). This part operates within a narrower supply voltage range (4V to 28V single supply, ±2V to ±14V dual supply) compared to AD810AN. LT1252CN8#PBF is active and ROHS3 compliant.

LT1122CCN8#PBF and LT1122DCN8#PBF are J-FET amplifiers with substantially lower bandwidth (13 MHz) and slew rate (75V/µs). These parts are suitable only for applications where the AD810AN's performance specifications exceed system requirements. Both are active and ROHS3 compliant, with LT1122DCN8#PBF supporting extended operating temperature range (-40°C to 85°C).

All substitute parts are manufactured by Analog Devices Inc., share the 8-DIP through-hole package, and carry MSL 1 rating. Selection must be based on specific application bandwidth, slew rate, supply voltage, and output current requirements.

Frequently Asked Questions (FAQ)

Q: Can AD810ANZ be used as a direct replacement for AD810AN?

A: Yes. AD810ANZ maintains identical electrical specifications including 80 MHz bandwidth, 1000V/µs slew rate, 6.8 mA supply current, 60 mA output current, and supply voltage ranges (5V to 36V single supply, ±2.5V to ±18V dual supply). Both use 8-DIP through-hole packaging. AD810ANZ is active and ROHS3 compliant, whereas AD810AN is obsolete.

Q: What are the key differences between LT1228 variants and AD810AN?

A: LT1228CN8#PBF and LT1228IN8#PBF provide higher bandwidth (100 MHz versus 80 MHz) and significantly higher slew rate (3500V/µs versus 1000V/µs). LT1228IN8#PBF offers higher output current (125 mA versus 60 mA). Both maintain current feedback topology and 8-DIP packaging. Operating temperature ranges differ between variants.

Q: When should LT1252CN8#PBF be selected over AD810AN?

A: LT1252CN8#PBF is selected when applications require bandwidth exceeding 80 MHz, specifically 282 MHz. However, LT1252CN8#PBF operates at lower slew rate (125V/µs versus 1000V/µs) and narrower supply voltage range (4V to 28V single supply, ±2V to ±14V dual supply). Circuit redesign may be necessary to accommodate these parameter differences.

Q: Are LT1122 parts suitable substitutes for AD810AN?

A: LT1122CCN8#PBF and LT1122DCN8#PBF are J-FET amplifiers with substantially lower performance specifications: 13 MHz bandwidth and 75V/µs slew rate. These parts are suitable only for applications where AD810AN performance exceeds system requirements. They share 8-DIP packaging and supply voltage compatibility (10V to 36V).

Q: What packaging considerations apply to all substitute parts?

A: All substitute parts use 8-DIP (0.300", 7.62mm) through-hole packages, maintaining identical PCB footprint and mounting compatibility with AD810AN. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute parts carry RoHS compliance?

A: AD810ANZ, LT1228CN8#PBF, LT1228IN8#PBF, LT1252CN8#PBF, LT1122CCN8#PBF, and LT1122DCN8#PBF all carry ROHS3 compliance certification. The original AD810AN does not specify RoHS status.

Q: How do supply voltage ranges compare across substitute options?

A: AD810AN and AD810ANZ support 5V to 36V (single supply) or ±2.5V to ±18V (dual supply). LT1228 variants support 4V to 36V (single supply). LT1252CN8#PBF supports 4V to 28V (single supply) or ±2V to ±14V (dual supply). LT1122 variants support 10V to 36V (single supply). Verify supply voltage compatibility before substitution.
