Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

Select LMH6702MA/NOPB or LMH6702MAX/NOPB when electrical specifications must remain unchanged from the original LMH6702MA design. Both parts maintain identical slew rate, bandwidth, and supply voltage requirements. LMH6702MAX/NOPB offers significantly higher inventory (17085 pcs) compared to LMH6702MA/NOPB (1320 pcs), making it the preferred choice for volume production. Both parts are Active status and ROHS3 compliant.

For Higher Performance Applications:

The AD8009ARZ family (AD8009ARZ, AD8009ARZ-REEL, AD8009ARZ-REEL7) provides enhanced slew rate performance (5500 V/µs versus 3100 V/µs) and higher output current capability (175 mA versus 80 mA). These parts are suitable for applications requiring faster transient response and greater output drive capability. Trade-offs include reduced bandwidth (1 GHz versus 1.7 GHz), higher input bias current (50 µA versus 6 µA), and wider supply voltage tolerance (5-12 V versus 10-12 V). AD8009ARZ-REEL7 provides the highest inventory availability (15100 pcs) within this family.

For Low-Power Applications:

The MAX4224ESA+T is optimized for reduced power consumption (6 mA supply current versus 12.5 mA) and lower input bias current (4 µA). This part is suitable for battery-powered or thermally constrained designs. Performance trade-offs include lower slew rate (1700 V/µs), reduced bandwidth (600 MHz), and narrower supply voltage range (5.7-11 V). Inventory is limited (1100 pcs).

Compliance Considerations:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Frequently Asked Questions (FAQ)

Q1: Can LMH6702MA/NOPB be used as a direct replacement for LMH6702MA?

A: Yes. LMH6702MA/NOPB is electrically identical to LMH6702MA with identical slew rate (3100 V/µs), bandwidth (1.7 GHz), and supply voltage requirements (10-12 V). The difference is packaging format (Tube versus original specification). Both are 8-SOIC surface mount packages with identical pinout and electrical performance.

Q2: What are the key differences between LMH6702MA and AD8009ARZ?

A: The primary differences are: (1) Slew Rate: AD8009ARZ is 5500 V/µs versus LMH6702MA at 3100 V/µs; (2) Bandwidth: LMH6702MA is 1.7 GHz versus AD8009ARZ at 1 GHz; (3) Input Bias Current: AD8009ARZ is 50 µA versus LMH6702MA at 6 µA; (4) Output Current: AD8009ARZ is 175 mA versus LMH6702MA at 80 mA; (5) Supply Voltage Range: AD8009ARZ operates from 5-12 V versus LMH6702MA from 10-12 V. Selection depends on whether higher slew rate or higher bandwidth is required for the application.

Q3: Is MAX4224ESA+T suitable for high-frequency applications?

A: No. MAX4224ESA+T has reduced bandwidth (600 MHz) and lower slew rate (1700 V/µs) compared to LMH6702MA (1.7 GHz bandwidth, 3100 V/µs slew rate). MAX4224ESA+T is optimized for lower power consumption and lower input bias current, making it suitable for low-frequency or DC-coupled applications where power efficiency is prioritized over bandwidth performance.

Q4: What is the difference between AD8009ARZ, AD8009ARZ-REEL, and AD8009ARZ-REEL7?

A: All three parts are electrically identical with identical electrical specifications. The differences are packaging formats: AD8009ARZ is supplied in Tube packaging, AD8009ARZ-REEL is supplied in Cut Tape & Digi-Reel format, and AD8009ARZ-REEL7 is also supplied in Cut Tape & Digi-Reel format. Inventory availability differs: AD8009ARZ-REEL7 has the highest stock (15100 pcs), followed by AD8009ARZ (8702 pcs), and AD8009ARZ-REEL (3400 pcs).

Q5: Can I use LMH6702MAX/NOPB in a design originally specified for LMH6702MA?

A: Yes. LMH6702MAX/NOPB is electrically and functionally identical to LMH6702MA. The manufacturer is National Semiconductor instead of Texas Instruments, but electrical specifications, pinout, package type (8-SOIC), and operating temperature range (-40°C to 85°C) are identical. LMH6702MAX/NOPB offers superior inventory availability (17085 pcs) for production applications.

Q6: What supply voltage range must be considered when selecting a substitute?

A: The original LMH6702MA requires 10-12 V supply voltage. LMH6702MA/NOPB and LMH6702MAX/NOPB maintain this requirement. AD8009ARZ family accepts wider range (5-12 V), allowing operation in lower voltage systems. MAX4224ESA+T operates from 5.7-11 V, which is narrower than LMH6702MA. Verify that the substitute part's supply voltage range is compatible with your power supply design.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (LMH6702MA/NOPB, LMH6702MAX/NOPB, AD8009ARZ, AD8009ARZ-REEL, AD8009ARZ-REEL7, and MAX4224ESA+T) are ROHS3 compliant. All parts are also REACH unaffected and classified as EAR99 for export control purposes.

Q8: Which substitute offers the best inventory availability?

A: LMH6702MAX/NOPB offers the highest inventory (17085 pcs), followed by AD8009ARZ-REEL7 (15100 pcs). If direct electrical equivalence is required, LMH6702MAX/NOPB is the optimal choice for volume production. If higher performance is acceptable, AD8009ARZ-REEL7 provides excellent availability with enhanced slew rate capability.
