Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8014ARTZ-R2 is determined by the following critical parameters: amplifier topology (current feedback), single-circuit configuration, package type (SOT-23-5), surface mount compatibility, and operating temperature range (-40°C to 85°C). Substitute parts must maintain electrical performance within acceptable ranges for slew rate, bandwidth, input bias current, input offset voltage, supply current, output current capability, and supply voltage specifications.

The substitute parts identified fall into two functional categories:

Category 1: Current Feedback Amplifiers (Direct Topology Match) Parts EL5161IWZ-T7, EL5161IWZ-T7A, and LMH6714MFX/NOPB maintain the current feedback topology. These devices operate within the same package and temperature specifications but exhibit reduced slew rate and bandwidth performance compared to the AD8014ARTZ-R2.

Category 2: Voltage Feedback Amplifier (Alternative Topology) Part MAX4105EUK+T employs voltage feedback topology rather than current feedback. This represents a functional alternative for applications where the feedback architecture can be adapted to accommodate voltage feedback operation.

All substitute parts are housed in SC-74A/SOT-753 packages suitable for surface mount assembly and operate across the -40°C to 85°C temperature range.

Engineering Selection Recommendations

For Direct Current Feedback Topology Replacement:

The EL5161IWZ-T7A represents the most suitable substitute when current feedback topology must be maintained. This Renesas Electronics device is active in production, ROHS3 compliant, and provides 140 mA output current capability, exceeding the AD8014ARTZ-R2 specification of 50 mA. The EL5161IWZ-T7A operates within the required temperature range and maintains identical input bias current (5 µA) and superior input offset voltage (1.6 mV versus 2 mV). Supply voltage compatibility spans 5 V to 10 V, which overlaps the AD8014ARTZ-R2 range of 4.5 V to 12 V. Slew rate and bandwidth are reduced (1700 V/µs and 200 MHz respectively), requiring circuit evaluation for timing-critical applications.

The EL5161IWZ-T7 provides identical electrical performance to the EL5161IWZ-T7A with reduced output current capability (not specified), suitable for applications not requiring the higher output current of the -T7A variant.

The LMH6714MFX/NOPB offers intermediate performance with 400 MHz bandwidth and 1800 V/µs slew rate, positioned between the reduced performance of the EL5161 series and the original AD8014ARTZ-R2. This device is active in production and provides 70 mA output current capability.

For Voltage Feedback Alternative:

The MAX4105EUK+T operates with voltage feedback topology and is ROHS3 compliant with unlimited moisture sensitivity (MSL 1). This device provides 410 MHz bandwidth and 70 mA output current. Supply voltage range (7 V to 11 V) is narrower than the AD8014ARTZ-R2 but overlaps the core operating range. Input bias current is elevated at 32 µA. This substitute requires circuit redesign to accommodate voltage feedback architecture and is suitable only when topology conversion is feasible.

All substitute parts maintain surface mount compatibility and the required operating temperature range. Selection should prioritize active production status and compliance certifications for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the EL5161IWZ-T7A directly replace the AD8014ARTZ-R2 without circuit modification?

A: The EL5161IWZ-T7A shares identical package, pinout, and current feedback topology with the AD8014ARTZ-R2. However, reduced slew rate (1700 V/µs versus 4600 V/µs) and bandwidth (200 MHz versus 480 MHz) require circuit evaluation. Applications dependent on the original slew rate or bandwidth specifications may require design adjustment. Supply voltage compatibility exists within the overlapping range of 5 V to 10 V.

Q: What is the primary difference between the EL5161IWZ-T7 and EL5161IWZ-T7A?

A: Both devices are manufactured by Renesas Electronics and provide identical electrical performance in slew rate, bandwidth, input bias current, and input offset voltage. The EL5161IWZ-T7A specifies 140 mA output current per channel, while the EL5161IWZ-T7 does not provide this specification. For applications requiring confirmed output current capability, the EL5161IWZ-T7A is the specified choice.

Q: Why is the MAX4105EUK+T listed as a substitute if it uses voltage feedback instead of current feedback?

A: The MAX4105EUK+T is included as a functional alternative for applications where circuit topology can accommodate voltage feedback operation. This device provides comparable bandwidth (410 MHz) and output current (70 mA) in the same package. Substitution requires circuit redesign and is not a direct pin-compatible replacement.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are housed in SC-74A/SOT-753 packages suitable for surface mount assembly. Packaging formats differ: EL5161IWZ-T7 and EL5161IWZ-T7A are supplied in Tape & Reel format; LMH6714MFX/NOPB is supplied in Bulk; MAX4105EUK+T is supplied in Tape & Reel format. Verify packaging compatibility with assembly requirements.

Q: What is the impact of reduced supply current in the EL5161 series compared to the AD8014ARTZ-R2?

A: The EL5161IWZ-T7 and EL5161IWZ-T7A consume 0.75 mA supply current versus 1.15 mA for the AD8014ARTZ-R2, representing a 35% reduction. This lower power consumption is beneficial for battery-powered or thermally constrained applications. No circuit modification is required to accommodate this difference.

Q: Which substitute part provides the closest performance match to the AD8014ARTZ-R2?

A: The LMH6714MFX/NOPB provides the closest performance match with 400 MHz bandwidth and 1800 V/µs slew rate, compared to the AD8014ARTZ-R2 specifications of 480 MHz and 4600 V/µs. This device maintains current feedback topology and provides 70 mA output current capability. Supply voltage range (8 V to 12.5 V single supply, ±4 V to ±6.25 V dual supply) overlaps the original specification.

Q: Are all substitute parts RoHS compliant?

A: EL5161IWZ-T7, EL5161IWZ-T7A, and MAX4105EUK+T are confirmed ROHS3 compliant. LMH6714MFX/NOPB RoHS status is not specified in the provided data. Verify RoHS compliance with the manufacturer or distributor if regulatory compliance is required.

Q: What is the moisture sensitivity consideration for long-term storage?

A: The AD8014ARTZ-R2 and MAX4105EUK+T have MSL 1 (Unlimited), allowing indefinite storage without moisture precautions. The EL5161IWZ-T7 and EL5161IWZ-T7A have MSL 2 (1 Year), requiring controlled storage conditions and moisture barrier packaging. LMH6714MFX/NOPB MSL is not specified. For applications with extended storage requirements, MSL 1 devices are preferred.
