Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8014ARTZ-REEL is determined by compatibility across the following critical parameters: package type (SOT-23-5), mounting configuration (surface mount), operating temperature range (-40°C to 85°C), supply voltage span (4.5 V to 12 V), and functional classification (single-circuit amplifier).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Amplifier Type): AD8014ARTZ-REEL7 maintains identical electrical specifications and amplifier topology (Current Feedback), differing only in product status (Active vs. Obsolete) and packaging format (Digi-Reel® vs. standard reel).

Functional Alternatives (Different Amplifier Type): MAX4105EUK+T and LMH6714MFX/NOPB provide comparable performance within the same package footprint and operating envelope, though with variations in amplifier feedback topology, bandwidth, slew rate, and supply current characteristics. These alternatives are suitable when the specific feedback architecture is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: AD8014ARTZ-REEL7

The AD8014ARTZ-REEL7 is the direct equivalent substitute for the obsolete AD8014ARTZ-REEL. This part maintains identical electrical performance specifications, including slew rate (4600 V/µs), bandwidth (480 MHz), and supply current characteristics. The AD8014ARTZ-REEL7 is classified as Active product status, ensuring long-term availability and supply chain continuity. The part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. The only functional difference is packaging format (Digi-Reel® vs. standard reel), which does not affect circuit performance or pin compatibility.

Secondary Recommendation: MAX4105EUK+T

The MAX4105EUK+T is suitable for applications where voltage feedback topology is acceptable and lower supply current is beneficial (20 mA vs. 1.15 mA). This part is Active, ROHS3 Compliant, and REACH Unaffected. The MAX4105EUK+T operates within the required temperature range (-40°C to 85°C) and maintains SOT-23-5 package compatibility. Trade-offs include reduced slew rate (1400 V/µs vs. 4600 V/µs) and slightly lower bandwidth (410 MHz vs. 480 MHz), with higher input bias current (32 µA vs. 5 µA).

Tertiary Recommendation: LMH6714MFX/NOPB

The LMH6714MFX/NOPB maintains Current Feedback topology and SOT-23-5 package compatibility. This part is Active and suitable for applications where moderate slew rate (1800 V/µs) and bandwidth (400 MHz) are acceptable. The LMH6714MFX/NOPB exhibits higher supply current (5.6 mA) compared to the primary part. Supply voltage compatibility requires verification for dual-supply configurations (±4 V to ±6.25 V or 8 V to 12.5 V single supply).

Frequently Asked Questions (FAQ)

Q: Can AD8014ARTZ-REEL7 be used as a direct replacement for AD8014ARTZ-REEL?

A: Yes. The AD8014ARTZ-REEL7 is electrically and functionally identical to the AD8014ARTZ-REEL. Both parts feature identical slew rate (4600 V/µs), bandwidth (480 MHz), supply current (1.15 mA), and operating temperature range (-40°C to 85°C). The parts are pin-compatible in SOT-23-5 packages. The primary difference is product status (Active vs. Obsolete) and packaging format (Digi-Reel® vs. standard reel).

Q: What are the key differences between Current Feedback and Voltage Feedback amplifiers?

A: Current Feedback amplifiers (AD8014ARTZ-REEL, AD8014ARTZ-REEL7, LMH6714MFX/NOPB) and Voltage Feedback amplifiers (MAX4105EUK+T) differ in feedback topology and performance characteristics. The AD8014ARTZ-REEL and AD8014ARTZ-REEL7 deliver higher slew rate (4600 V/µs) and lower input bias current (5 µA). The MAX4105EUK+T, as a voltage feedback device, provides lower slew rate (1400 V/µs) but may offer different stability characteristics in specific circuit configurations. Selection depends on application requirements for transient response and input impedance.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts (AD8014ARTZ-REEL7, LMH6714MFX/NOPB, MAX4105EUK+T) are housed in SOT-23-5 packages with identical pin configurations (SC-74A, SOT-753). PCB footprints are mechanically and electrically compatible without modification.

Q: What is the significance of the Digi-Reel® packaging format in AD8014ARTZ-REEL7?

A: Digi-Reel® is a packaging and delivery format that does not affect electrical performance or pin compatibility. The format impacts supply chain logistics and handling procedures but does not alter circuit functionality or performance characteristics.

Q: Does the MAX4105EUK+T require different circuit design considerations?

A: The MAX4105EUK+T uses Voltage Feedback topology rather than Current Feedback. This difference may require circuit design adjustments, particularly in feedback network configuration and stability compensation. The higher input bias current (32 µA vs. 5 µA) and lower slew rate (1400 V/µs vs. 4600 V/µs) must be evaluated against application requirements. Supply voltage range (7 V to 11 V) is narrower than the primary part (4.5 V to 12 V).

Q: What compliance certifications are relevant for new designs?

A: AD8014ARTZ-REEL7 and MAX4105EUK+T are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for new product designs. The LMH6714MFX/NOPB compliance status is not specified in available documentation.

Q: How does supply current affect component selection?

A: The AD8014ARTZ-REEL and AD8014ARTZ-REEL7 require 1.15 mA supply current, the lowest among available substitutes. The LMH6714MFX/NOPB requires 5.6 mA, and the MAX4105EUK+T requires 20 mA. Higher supply current increases power dissipation and thermal load. Selection depends on power budget constraints and thermal management capabilities of the application.

Q: Can LMH6714MFX/NOPB operate with single supply voltages below 8 V?

A: The LMH6714MFX/NOPB is specified for single supply operation from 8 V to 12.5 V or dual supply operation from ±4 V to ±6.25 V. This part is not suitable for applications requiring operation below 8 V single supply. The AD8014ARTZ-REEL and AD8014ARTZ-REEL7 support lower supply voltages (4.5 V minimum).
