Engineering Selection Recommendations

Primary Substitutes (Voltage Feedback Topology):

LMH6655MA/NOPB and LMH6655MAX/NOPB are direct functional equivalents manufactured by Texas Instruments with active product status and ROHS3 compliance. Both devices maintain the voltage feedback amplifier architecture with 2 circuits in 8-SOIC packaging. The LMH6655MAX/NOPB variant is supplied in Tape & Reel packaging with higher inventory availability (2787 pcs). These parts are suitable for applications where the CLC2000ISO8X output current requirement of 1A can be reduced to 120mA per channel.

LMH6658MA/NOPB, manufactured by National Semiconductor, provides enhanced slew rate performance (700V/µs) and rail-to-rail output capability. This part extends the minimum supply voltage to 3V and maintains active product status. Selection of this part is appropriate for applications requiring improved transient response and lower supply voltage operation.

LMH6682MAX/NOPB offers the highest slew rate (940V/µs) among voltage feedback substitutes with active product status and ROHS3 compliance. This part is recommended for applications prioritizing high-speed signal conditioning with reduced output current requirements (85mA per channel).

LMH6672MAX/NOPB provides extended operating temperature range (-40°C to 150°C) with active product status. This part is suitable for applications requiring thermal performance beyond standard industrial range, though with reduced bandwidth (90 MHz) and slew rate (135V/µs).

Secondary Substitute (General Purpose Amplifier):

OPA2822U/2K5 is a general purpose amplifier with active product status and ROHS3 compliance. This part provides higher gain bandwidth product (240 MHz) and -3dB bandwidth (400 MHz) compared to most voltage feedback substitutes. Selection of this part requires circuit design verification due to the change in amplifier topology from voltage feedback to general purpose architecture.

All recommended substitutes are available in active product status with current manufacturing support and regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can LMH6655MA/NOPB directly replace CLC2000ISO8X in existing PCB designs?

A: Yes, LMH6655MA/NOPB is pin-compatible and maintains the same 8-SOIC package footprint (0.154", 3.90mm width). However, the output current per channel is reduced from 1A to 120mA. Circuit designs must be verified to confirm that load current requirements do not exceed 120mA per channel.

Q: What is the primary difference between LMH6655MA/NOPB and LMH6655MAX/NOPB?

A: Both parts are electrically identical with identical electrical specifications. The primary difference is packaging format: LMH6655MA/NOPB is supplied in Tube packaging, while LMH6655MAX/NOPB is supplied in Tape & Reel (TR) format. LMH6655MAX/NOPB has higher current inventory availability (2787 pcs vs. 1205 pcs).

Q: Why does LMH6658MA/NOPB have a lower gain bandwidth product (140 MHz) than the CLC2000ISO8X?

A: LMH6658MA/NOPB is optimized for rail-to-rail output operation and single-supply applications, resulting in different frequency response characteristics. The -3dB bandwidth specification of 270 MHz indicates adequate bandwidth for most signal conditioning applications despite the lower gain bandwidth product metric.

Q: Is OPA2822U/2K5 suitable as a substitute for CLC2000ISO8X?

A: OPA2822U/2K5 is functionally compatible in terms of package, pin count, and operating temperature range. However, this part is classified as a general purpose amplifier rather than voltage feedback topology. Circuit designs must be re-evaluated for stability and frequency response characteristics before substitution.

Q: What is the moisture sensitivity level (MSL) requirement for these substitute parts?

A: LMH6655MA/NOPB, LMH6655MAX/NOPB, LMH6672MAX/NOPB, and LMH6682MAX/NOPB all have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. OPA2822U/2K5 has MSL rating of 2 (1 Year), requiring controlled storage conditions.

Q: Are all substitute parts ROHS3 compliant?

A: LMH6655MA/NOPB, LMH6655MAX/NOPB, LMH6672MAX/NOPB, LMH6682MAX/NOPB, and OPA2822U/2K5 are all ROHS3 compliant. LMH6658MA/NOPB compliance status is not specified in the provided data.

Q: Which substitute part offers the best high-temperature performance?

A: LMH6672MAX/NOPB provides extended operating temperature range from -40°C to 150°C, compared to the standard -40°C to 85°C range of other substitutes. This part is recommended for applications requiring operation above 85°C.

Q: What is the supply voltage compatibility range for all substitute parts?

A: All substitute parts operate within the 5V to 12V supply range of the original CLC2000ISO8X. LMH6658MA/NOPB and LMH6682MAX/NOPB extend the minimum supply voltage to 3V, providing additional flexibility for low-voltage applications.
