Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8017AR is determined by electrical and mechanical compatibility across the following critical parameters: dual-circuit configuration, 8-SOIC surface-mount package, supply voltage range, output current capability, and operating temperature range. Substitute parts must maintain functional equivalence within the specified electrical performance envelope while meeting or exceeding the original part's operational requirements.

The AD8017AR has two substitute classifications:

Direct Substitute (Pin-Compatible, Electrical Equivalent): Parts that maintain identical electrical specifications and package footprint, enabling direct replacement without circuit modification.

Similar Substitute (Functional Equivalent, Package-Compatible): Parts that provide equivalent functionality within the same package form factor but with differing electrical characteristics, requiring design verification for specific application parameters.

Parameter Comparison

Engineering Selection Recommendations

AD8017ARZ (Direct Substitute): The AD8017ARZ is the primary equivalent for the obsolete AD8017AR. Both parts are manufactured by Analog Devices Inc. and share identical electrical specifications, including slew rate (1600 V/µs), gain-bandwidth product (105 MHz), -3dB bandwidth (160 MHz), input bias current (16 µA), input offset voltage (1.8 mV), supply current (7 mA per channel), output current (270 mA per channel), and supply voltage range (4.4 V to 12 V). The AD8017ARZ maintains the same 8-SOIC package footprint and operating temperature range (-40°C to 85°C). The critical distinction is product status: AD8017ARZ is active and carries RoHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory compliance. Packaging differs only in format (tube versus unspecified for the original), which does not affect electrical or mechanical compatibility. The AD8017ARZ is the recommended direct replacement for the AD8017AR.

LMH6672MA/NOPB (Similar Substitute): The LMH6672MA/NOPB, manufactured by National Semiconductor, provides functional equivalence as a dual-circuit operational amplifier in the 8-SOIC package. This part is active and suitable for applications where the AD8017AR specifications cannot be met. Key differences include lower slew rate (135 V/µs versus 1600 V/µs), reduced -3dB bandwidth (90 MHz versus 160 MHz), lower input bias current (8 µA versus 16 µA), significantly lower input offset voltage (100 µV versus 1.8 mV), higher output current capability (525 mA versus 270 mA per channel), and extended operating temperature range (-40°C to 150°C). The minimum supply voltage is 5 V (versus 4.4 V). The LMH6672MA/NOPB is classified as a voltage feedback amplifier rather than general purpose. Selection of this part requires design verification to confirm that reduced bandwidth and slew rate do not compromise application performance, while acknowledging benefits of improved offset voltage and output current capability.

Frequently Asked Questions (FAQ)

Q: Can the AD8017ARZ be used as a direct replacement for the AD8017AR without circuit modification?

A: Yes. The AD8017ARZ is electrically and mechanically identical to the AD8017AR across all specified parameters. Both parts feature identical slew rate, gain-bandwidth product, bandwidth, input bias current, input offset voltage, supply current, output current, and supply voltage range. The 8-SOIC package footprint is identical. No circuit modification is required for substitution.

Q: What are the key differences between the AD8017ARZ and LMH6672MA/NOPB?

A: The AD8017ARZ and LMH6672MA/NOPB differ in slew rate (1600 V/µs versus 135 V/µs), -3dB bandwidth (160 MHz versus 90 MHz), input bias current (16 µA versus 8 µA), input offset voltage (1.8 mV versus 100 µV), output current per channel (270 mA versus 525 mA), and operating temperature range (-40°C to 85°C versus -40°C to 150°C). Both are housed in 8-SOIC packages and support dual-circuit configurations. The LMH6672MA/NOPB is classified as a voltage feedback amplifier, while the AD8017ARZ is general purpose.

Q: Is the LMH6672MA/NOPB suitable for high-speed applications requiring 160 MHz bandwidth?

A: No. The LMH6672MA/NOPB has a -3dB bandwidth of 90 MHz, which is insufficient for applications requiring 160 MHz bandwidth. The AD8017ARZ maintains the full 160 MHz bandwidth specification of the original AD8017AR. Application requirements must be evaluated against the LMH6672MA/NOPB's reduced bandwidth before selection.

Q: What is the impact of the LMH6672MA/NOPB's lower slew rate on circuit performance?

A: The LMH6672MA/NOPB slew rate is 135 V/µs compared to 1600 V/µs for the AD8017AR and AD8017ARZ. Lower slew rate limits the rate of voltage change in the output signal, which may introduce distortion in high-frequency or high-amplitude signal applications. Applications sensitive to slew-rate-induced distortion require design verification before substituting the LMH6672MA/NOPB.

Q: Are there compliance or regulatory differences between the substitute parts?

A: The AD8017ARZ carries RoHS3 compliance and REACH unaffected certification, ensuring regulatory alignment with current environmental standards. The LMH6672MA/NOPB compliance status is not specified in the provided data. Regulatory requirements for the target application must be confirmed before final part selection.

Q: Can the AD8017AR be used in new designs?

A: No. The AD8017AR is classified as obsolete. New designs must use the AD8017ARZ (direct substitute) or evaluate the LMH6672MA/NOPB (similar substitute) based on application-specific electrical requirements. The AD8017ARZ is the recommended choice for designs requiring electrical equivalence to the original AD8017AR specification.

Q: What is the significance of the 8-SOIC package compatibility?

A: All three parts (AD8017AR, AD8017ARZ, and LMH6672MA/NOPB) are housed in 8-SOIC packages with identical physical dimensions (0.154" width, 3.90 mm). This ensures mechanical compatibility with existing printed circuit board layouts and assembly processes. No PCB redesign is required when substituting between these parts.

Q: How does the input offset voltage difference affect circuit design?

A: The AD8017AR and AD8017ARZ both specify 1.8 mV input offset voltage, while the LMH6672MA/NOPB specifies 100 µV. Lower input offset voltage reduces DC error in precision applications. If the application circuit includes offset nulling or is tolerant of 1.8 mV offset, both the AD8017ARZ and LMH6672MA/NOPB are acceptable. Precision applications requiring minimal offset should prioritize the LMH6672MA/NOPB.

Q: What is the maximum output current capability of each part?

A: The AD8017AR and AD8017ARZ both provide 270 mA output current per channel. The LMH6672MA/NOPB provides 525 mA output current per channel, nearly double the output current capability. Applications requiring high output current may benefit from the LMH6672MA/NOPB, provided bandwidth and slew rate requirements are satisfied.
