Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD818ANZ is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Pin count and footprint alignment

Functional Compatibility:

• Amplifier type: Voltage Feedback
• Number of circuits: 1
• Supply voltage range overlap with system requirements
• Output current capability sufficient for load requirements

Electrical Performance Boundaries:

• Slew rate: Substitute must meet or exceed application slew rate demands
• Bandwidth: Substitute must support required frequency response
• Supply current: Substitute power consumption must fit system budget
• Output current per channel: Substitute must deliver required load current

The LT1354CN8#PBF qualifies as a substitute based on identical mechanical packaging, matching voltage feedback amplifier topology, single-circuit configuration, and compatible through-hole mounting. Both parts are manufactured by Analog Devices Inc., maintain Active product status, and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: AD818ANZ

The AD818ANZ is the specified component for applications requiring 130 MHz bandwidth, 500 V/µs slew rate, 50 mA output current per channel, and supply voltage operation to 36V single supply. This part is Active in production status with established supply availability (2810 units in stock). ROHS3 compliance and unlimited moisture sensitivity rating support deployment in standard manufacturing and storage environments.

Substitute Part: LT1354CN8#PBF

The LT1354CN8#PBF serves as a substitute where the following conditions are met:

• Application bandwidth requirement does not exceed 12 MHz (Gain Bandwidth Product specification)
• Slew rate requirement is satisfied by 400 V/µs performance
• Output current requirement does not exceed 30 mA per channel
• Supply voltage operation within 5V to 30V range is acceptable
• Lower supply current consumption (1 mA versus 7 mA) is beneficial for power-constrained designs

Both parts maintain identical mechanical compatibility, identical amplifier topology classification, and equivalent regulatory compliance status. The LT1354CN8#PBF is Active in production with 1761 units in current inventory stock.

Selection Criteria:

Choose the AD818ANZ when high-speed performance (130 MHz bandwidth, 500 V/µs slew rate) and higher output current capability (50 mA) are required. Choose the LT1354CN8#PBF when lower power consumption and reduced output current demands align with application specifications, provided bandwidth and slew rate requirements are satisfied by the lower performance envelope.

Frequently Asked Questions (FAQ)

Q: Can the LT1354CN8#PBF directly replace the AD818ANZ in existing PCB designs?

A: Yes, from a mechanical and electrical interface perspective. Both parts use identical 8-DIP (0.300", 7.62mm) through-hole packaging with matching pin configurations for voltage feedback amplifier operation. PCB footprints and board layouts require no modification. However, circuit performance will differ due to reduced bandwidth (12 MHz versus 130 MHz), lower slew rate (400 V/µs versus 500 V/µs), and reduced output current capability (30 mA versus 50 mA). Verify that application performance requirements are satisfied by the LT1354CN8#PBF specifications before substitution.

Q: What are the key performance differences between these parts?

A: The AD818ANZ provides higher bandwidth (130 MHz), faster slew rate (500 V/µs), and greater output current per channel (50 mA). The LT1354CN8#PBF offers significantly lower supply current consumption (1 mA versus 7 mA) and operates within a narrower maximum supply voltage range (30V versus 36V). The LT1354CN8#PBF is optimized for lower-power applications with less demanding frequency response and output current requirements.

Q: Are there any supply voltage compatibility issues between these parts?

A: The LT1354CN8#PBF maximum supply voltage is 30V, while the AD818ANZ supports up to 36V single supply. If your application requires operation above 30V, the AD818ANZ is the only suitable choice. Both parts support minimum supply voltage of 5V and are compatible with dual supply configurations within their respective ranges.

Q: Do both parts have identical regulatory compliance?

A: Yes. Both the AD818ANZ and LT1354CN8#PBF are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control purposes, and carry identical HTSUS commodity codes (8542.33.0001). Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the inventory status for each part?

A: The AD818ANZ has 2810 units in current stock. The LT1354CN8#PBF has 1761 units in current stock. Both parts maintain Active production status with Analog Devices Inc.

Q: Can I use the LT1354CN8#PBF in a high-frequency video amplification circuit?

A: The LT1354CN8#PBF is not suitable for high-frequency video amplification applications. Its 12 MHz gain bandwidth product is insufficient for video signal processing, which typically requires bandwidth in the range of 50 MHz to 200 MHz. The AD818ANZ, with 130 MHz bandwidth, is the appropriate choice for video amplifier applications.
