Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPA2683IDRG4 is determined by the following mandatory criteria:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB footprint compatibility and automated assembly compatibility.

Amplifier Architecture: All substitutes must be current feedback amplifier topologies with dual-channel (2 circuit) configuration to maintain functional equivalence.

Operating Temperature Range: All substitutes must support the -40°C to 85°C operating temperature range to ensure thermal compatibility across specified environmental conditions.

Supply Voltage Range: Substitute parts must operate within or encompass the 5 V to 12 V supply voltage span. Parts with minimum supply voltage below 5 V or maximum supply voltage below 12 V are acceptable if the overlap region includes the full 5 V to 12 V range.

Output Configuration: Differential output configuration is preferred for direct pin-level compatibility; however, parts with unspecified output type may be substituted if all other electrical and mechanical parameters are met.

Electrical Performance: Substitute parts must meet or exceed the slew rate (540 V/µs minimum), gain bandwidth product (200 MHz minimum), and output current capability (150 mA per channel minimum) to ensure signal integrity and load-driving capability.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

OPA2683ID is the primary direct replacement for OPA2683IDRG4. Both parts are manufactured by Texas Instruments, share identical electrical specifications (540 V/µs slew rate, 200 MHz gain bandwidth product, 150 mA output current per channel), and operate across the -40°C to 85°C temperature range. The OPA2683ID is classified as active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 2, 1 Year). The primary difference is packaging format: OPA2683IDRG4 is supplied in tape and reel format, while OPA2683ID is supplied in tube format. This substitution requires no circuit redesign or performance verification.

Performance-Enhanced Substitutes (Higher Bandwidth and Slew Rate):

LMH6724MA/NOPB and LMH6724MAX/NOPB (National Semiconductor) provide enhanced performance with 600 V/µs slew rate and 370 MHz bandwidth, exceeding OPA2683IDRG4 specifications. Both maintain the 8-SOIC package, dual-channel configuration, and -40°C to 85°C operating temperature range. Supply current is reduced to 1 mA per channel (versus 1.88 mA), and input bias current is improved to 2 µA. However, output current per channel is reduced to 110 mA, which may limit applications requiring the full 150 mA output capability of the original part. Both LMH6724 variants are active products with confirmed inventory availability.

AD8008ARZ-REEL (Analog Devices Inc.) offers the highest performance envelope with 1000 V/µs slew rate and 500 MHz bandwidth. This part exceeds all OPA2683IDRG4 electrical specifications and is ROHS3 compliant with superior moisture sensitivity (MSL 1, Unlimited). However, supply current increases to 9 mA per channel, and output current per channel is 130 mA. This substitute is appropriate for applications requiring maximum bandwidth and slew rate performance where increased power consumption is acceptable.

MAX4227ESA+ (Analog Devices Inc./Maxim Integrated) provides the highest slew rate (1700 V/µs) and bandwidth (600 MHz) among all substitutes. Input offset voltage is minimized at 500 µV, and moisture sensitivity is MSL 1 (Unlimited). Supply current is 6 mA per channel. Output current per channel is 80 mA, which falls below the OPA2683IDRG4 specification of 150 mA. Supply voltage maximum is 11 V, which is below the 12 V maximum of the original part. This substitute is suitable for applications where maximum bandwidth and slew rate are prioritized and output current requirements do not exceed 80 mA.

Compliance and Regulatory Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original OPA2683IDRG4. All parts carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can OPA2683ID be used as a direct replacement for OPA2683IDRG4 without circuit modification?

A: Yes. OPA2683ID is electrically and functionally identical to OPA2683IDRG4. Both parts share the same slew rate (540 V/µs), gain bandwidth product (200 MHz), output current capability (150 mA per channel), and operating temperature range (-40°C to 85°C). The only difference is packaging format (tube versus tape and reel). No circuit redesign or performance verification is required. Both parts are ROHS3 compliant and carry identical moisture sensitivity levels.

Q: What is the primary reason to substitute OPA2683IDRG4?

A: OPA2683IDRG4 is classified as obsolete product status. OPA2683ID, the direct replacement, is classified as active and ensures continued availability for new production and long-term supply chain stability. Substitution is necessary to avoid future supply discontinuation and to maintain design continuity.

Q: Are the LMH6724MA/NOPB and LMH6724MAX/NOPB interchangeable with OPA2683IDRG4?

A: Both LMH6724 variants are pin-compatible and package-compatible substitutes with enhanced performance specifications. They provide higher slew rate (600 V/µs versus 540 V/µs) and bandwidth (370 MHz versus 200 MHz). However, output current per channel is reduced to 110 mA compared to the original 150 mA. These substitutes are appropriate for applications where the reduced output current is acceptable and enhanced bandwidth is beneficial.

Q: What are the key differences between AD8008ARZ-REEL and OPA2683IDRG4?

A: AD8008ARZ-REEL exceeds OPA2683IDRG4 across all performance metrics: slew rate is 1000 V/µs (versus 540 V/µs), bandwidth is 500 MHz (versus 200 MHz), and input offset voltage is 500 µV (versus 1.5 mV). However, supply current increases to 9 mA per channel (versus 1.88 mA), and output current per channel is 130 mA (versus 150 mA). This substitute is suitable for high-performance applications where increased power consumption is acceptable.

Q: Is MAX4227ESA+ suitable for all applications using OPA2683IDRG4?

A: MAX4227ESA+ provides the highest slew rate (1700 V/µs) and bandwidth (600 MHz) among all substitutes. However, output current per channel is limited to 80 mA, which is below the OPA2683IDRG4 specification of 150 mA. Additionally, maximum supply voltage is 11 V, which is below the original 12 V maximum. This substitute is appropriate only for applications where output current does not exceed 80 mA and supply voltage does not exceed 11 V.

Q: Do all substitute parts maintain the same package footprint as OPA2683IDRG4?

A: Yes. All substitute parts listed use the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring identical PCB footprint compatibility and automated assembly compatibility with OPA2683IDRG4 designs.

Q: Are there any compliance or regulatory differences between OPA2683IDRG4 and its substitutes?

A: No. All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. Regulatory equivalence is maintained across all substitutes.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across the -40°C to 85°C temperature range, identical to OPA2683IDRG4. This ensures thermal compatibility across all specified environmental conditions.

Q: Which substitute part provides the best balance of performance and power consumption?

A: LMH6724MA/NOPB and LMH6724MAX/NOPB provide enhanced performance (600 V/µs slew rate, 370 MHz bandwidth) with reduced supply current (1 mA per channel versus 1.88 mA). These substitutes are appropriate for applications where bandwidth improvement is desired and output current requirements do not exceed 110 mA per channel.

Q: Can substitute parts with lower output current capability be used in designs requiring 150 mA per channel?

A: No. Substitute parts with output current specifications below 150 mA per channel (LMH6724 variants at 110 mA, MAX4227ESA+ at 80 mA) cannot be used in applications requiring the full 150 mA output capability. AD8008ARZ-REEL at 130 mA is also below specification. Only OPA2683ID maintains the full 150 mA per channel output current capability.
