LMH6723MA Equivalent & Substitute Parts

Part Overview

The LMH6723MA is a current feedback amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating limited availability from the original manufacturer. The LMH6723MA delivers high-speed amplification with a 370 MHz bandwidth and 600V/µs slew rate, suitable for applications requiring fast signal processing in compact form factors.

Due to Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term supply chain planning. Substitute parts must maintain compatibility across electrical performance parameters, mechanical packaging, and operating conditions.

Substitution Categories:

Category 1: Direct Texas Instruments Variants LMH6723MA/NOPB and LMH6723MAX/NOPB are packaging variants of the same base product (LMH6723). These parts maintain identical electrical specifications and differ only in packaging format (Tube vs. Tape & Reel). Both are Active status products with higher inventory availability than the Last Time Buy LMH6723MA.

Category 2: Analog Devices AD8014 Series AD8014ARZ, AD8014ARZ-REEL, and AD8014ARZ-REEL7 are current feedback amplifiers from Analog Devices Inc. with enhanced performance characteristics. These parts share the same 8-SOIC package and supply voltage range. Performance parameters exceed the LMH6723MA specification in slew rate (4600V/µs vs. 600V/µs) and bandwidth (480 MHz vs. 370 MHz), while maintaining compatibility with the same mechanical and thermal requirements.

Category 3: Analog Devices LT1395 Series LT1395CS8#PBF and LT1395CS8#TRPBF are current feedback amplifiers with intermediate performance characteristics. These parts operate within the same 8-SOIC package and 4.5V to 12V supply range. Operating temperature range is 0°C to 70°C, which is narrower than the LMH6723MA. Slew rate (800V/µs) and bandwidth (400 MHz) fall between the LMH6723MA and AD8014 specifications.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

LMH6723MA/NOPB and LMH6723MAX/NOPB are the primary substitutes when electrical specifications must remain unchanged. Both parts maintain 100% compatibility with the original LMH6723MA across all electrical parameters. LMH6723MA/NOPB is available in Tube packaging, while LMH6723MAX/NOPB is supplied in Tape & Reel format. Selection between these variants depends on assembly process requirements. Both parts carry Active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy LMH6723MA.

For Enhanced Performance Applications:

The AD8014ARZ series (AD8014ARZ, AD8014ARZ-REEL, AD8014ARZ-REEL7) provides superior performance characteristics with 4600V/µs slew rate and 480 MHz bandwidth. These parts are suitable for applications where higher speed and bandwidth margins are beneficial. All three variants maintain the same electrical specifications and differ only in packaging format. The AD8014ARZ series operates within the same -40°C to 85°C temperature range and 4.5V to 12V supply voltage range as the LMH6723MA. Output current capability is reduced to 50 mA per channel compared to 110 mA for the LMH6723MA, which must be evaluated against circuit requirements.

For Intermediate Performance with Extended Supply Range:

The LT1395CS8 series (LT1395CS8#PBF and LT1395CS8#TRPBF) offers balanced performance with 800V/µs slew rate and 400 MHz bandwidth. These parts support operation at supply voltages as low as 4V, compared to 4.5V minimum for other candidates. Operating temperature range is limited to 0°C to 70°C, which is narrower than the LMH6723MA specification. Supply current is higher at 4.6 mA compared to 1 mA for the LMH6723MA. Selection of LT1395CS8 variants is appropriate when lower supply voltage operation is required and the narrower temperature range is acceptable.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the LMH6723MA. All parts carry EAR99 export classification and are REACH Unaffected, ensuring regulatory compatibility across manufacturing and distribution channels.

Frequently Asked Questions (FAQ)

Q: Can LMH6723MA/NOPB and LMH6723MAX/NOPB be used interchangeably with LMH6723MA?

A: Yes. LMH6723MA/NOPB and LMH6723MAX/NOPB are functionally identical to LMH6723MA across all electrical specifications. The differences are packaging format only: LMH6723MA/NOPB is supplied in Tube packaging, while LMH6723MAX/NOPB is supplied in Tape & Reel format. Selection depends on assembly process compatibility. Both parts are Active status products with superior supply availability compared to the Last Time Buy LMH6723MA.

Q: What are the key differences between the LMH6723MA and AD8014ARZ series?

A: The AD8014ARZ series provides enhanced performance with 4600V/µs slew rate and 480 MHz bandwidth compared to 600V/µs and 370 MHz for the LMH6723MA. Input bias current is higher at 5 µA versus 2 µA. Output current per channel is reduced to 50 mA versus 110 mA. Both families operate within the same -40°C to 85°C temperature range and 4.5V to 12V supply voltage range. The AD8014ARZ series is suitable for applications requiring higher speed performance.

Q: Can the LT1395CS8 series replace the LMH6723MA in all applications?

A: The LT1395CS8 series shares the same 8-SOIC package and current feedback amplifier topology. However, operating temperature range is limited to 0°C to 70°C, which is narrower than the LMH6723MA specification of -40°C to 85°C. Supply current is significantly higher at 4.6 mA compared to 1 mA. Output current per channel is 80 mA versus 110 mA. The LT1395CS8 series is suitable only for applications where the narrower temperature range and higher supply current are acceptable.

Q: Are all substitute parts available in both Tube and Tape & Reel packaging?

A: No. LMH6723MA/NOPB is available in Tube packaging only. LMH6723MAX/NOPB, AD8014ARZ-REEL, AD8014ARZ-REEL7, and LT1395CS8#TRPBF are available in Tape & Reel format. AD8014ARZ and LT1395CS8#PBF are available in Tube packaging. Packaging selection must align with assembly equipment capabilities and production volume requirements.

Q: What is the significance of the Last Time Buy status for LMH6723MA?

A: Last Time Buy status indicates that Texas Instruments has discontinued or will discontinue production of the LMH6723MA. This status limits future availability and increases supply risk. Transitioning to Active status alternatives such as LMH6723MA/NOPB, LMH6723MAX/NOPB, or other substitute parts ensures long-term design continuity and supply chain stability.

Q: Do all substitute parts meet the same compliance requirements as the LMH6723MA?

A: Yes. All substitute parts listed maintain ROHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, EAR99 export classification, and REACH Unaffected status. Regulatory and environmental compliance is consistent across all candidates.

Q: Which substitute part offers the best performance-to-power-consumption ratio?

A: The AD8014ARZ series provides the highest performance (4600V/µs slew rate, 480 MHz bandwidth) with minimal supply current increase (1.15 mA versus 1 mA for LMH6723MA). The LT1395CS8 series offers intermediate performance with significantly higher supply current (4.6 mA), making it less efficient for power-sensitive applications. For applications prioritizing performance efficiency, the AD8014ARZ series is the optimal choice.
