Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA2683IDR is determined by strict alignment of electrical and mechanical parameters within the current feedback amplifier category. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

• Amplifier Type: Current Feedback (mandatory)
• Number of Circuits: 2 (mandatory)
• Package / Case: 8-SOIC form factor (mandatory for direct PCB compatibility)
• Mounting Type: Surface Mount (mandatory)
• Operating Temperature Range: -40°C to 85°C (mandatory)
• Voltage Supply Span: Minimum 5V, Maximum 12V (mandatory for power supply compatibility)

Secondary Compatibility Parameters:

• Slew Rate: 540V/µs or higher (performance preservation)
• Current - Output / Channel: 150 mA or higher (load-driving capability)
• Current - Input Bias: 3 µA or lower (input impedance characteristics)
• Voltage - Input Offset: 1.5 mV or lower (DC accuracy)

Substitute parts are classified into two categories: MFR Recommended (manufacturer-validated alternatives) and Direct Manufacturer (same-family variants with identical electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

OPA2683ID (Direct Manufacturer Substitute)

The OPA2683ID is the primary substitute for the OPA2683IDR. Both devices are manufactured by Texas Instruments and share identical electrical specifications: 540V/µs slew rate, 200 MHz gain bandwidth product, 3 µA input bias current, 1.5 mV input offset voltage, and 150 mA output current per channel. The OPA2683ID is classified as Active product status, ensuring long-term availability and manufacturing support. Both parts are ROHS3 compliant and operate across the -40°C to 85°C temperature range. The primary difference is packaging: OPA2683IDR is supplied in Bulk packaging, while OPA2683ID is supplied in Tube packaging. This variant is recommended for applications requiring exact electrical performance matching and Texas Instruments product continuity.

LMH6724MA/NOPB and LMH6724MAX/NOPB (MFR Recommended Substitutes)

The LMH6724MA/NOPB and LMH6724MAX/NOPB are National Semiconductor current feedback amplifiers with enhanced performance characteristics. Both devices feature 600V/µs slew rate (11% improvement over OPA2683IDR), 370 MHz bandwidth, and 2 µA input bias current. Output current per channel is 110 mA, which is lower than the OPA2683IDR's 150 mA specification. These devices operate across -40°C to 85°C and are housed in 8-SOIC packages. Minimum supply voltage is 4.5V, providing broader supply compatibility. Both LMH6724 variants are classified as Active product status. These substitutes are suitable for applications where higher slew rate and bandwidth are beneficial and output current requirements do not exceed 110 mA per channel.

EL5263ISZ-T7 (Alternative Substitute)

The EL5263ISZ-T7 is a Renesas Electronics current feedback amplifier with exceptional performance: 4000V/µs slew rate and 500 MHz bandwidth. Input bias current is 2 µA and input offset voltage is 1.5 mV. Output current per channel is 100 mA. The device operates across -40°C to 85°C and is housed in 8-SOIC package. EL5263ISZ-T7 is classified as Obsolete product status. This device is suitable for high-speed applications where maximum slew rate and bandwidth are critical, provided that output current requirements do not exceed 100 mA per channel and long-term availability is not a primary concern.

Compliance and Certification Alignment

All substitute parts maintain ROHS3 compliance and operate within the -40°C to 85°C industrial temperature range. Supply voltage compatibility spans 4.5V to 12V across all substitutes, with the OPA2683IDR and OPA2683ID requiring minimum 5V. Selection should prioritize Active product status devices (OPA2683ID, LMH6724MA/NOPB, LMH6724MAX/NOPB) for production applications requiring long-term component availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the LMH6724MA/NOPB directly replace the OPA2683IDR without circuit modification?

A: The LMH6724MA/NOPB is pin-compatible and operates within the same 8-SOIC package footprint. However, output current per channel is 110 mA versus 150 mA for the OPA2683IDR. If the application requires output current exceeding 110 mA per channel, external buffering or load impedance adjustment is necessary. Slew rate and bandwidth are superior in the LMH6724MA/NOPB, which may require PCB layout review for high-frequency applications to prevent oscillation.

Q: What is the difference between OPA2683IDR and OPA2683ID?

A: Both devices are manufactured by Texas Instruments and have identical electrical specifications. The difference is packaging: OPA2683IDR is supplied in Bulk packaging, while OPA2683ID is supplied in Tube packaging. Electrical performance, temperature range, and supply voltage specifications are identical. Selection depends on procurement and handling requirements.

Q: Is the EL5263ISZ-T7 suitable for production applications?

A: The EL5263ISZ-T7 is classified as Obsolete product status. While it offers superior slew rate (4000V/µs) and bandwidth (500 MHz), obsolete status indicates limited future availability and potential manufacturing discontinuation. For production applications requiring long-term component supply, Active status devices (OPA2683ID, LMH6724MA/NOPB, LMH6724MAX/NOPB) are recommended.

Q: What are the key electrical differences between substitute parts?

A: Slew rate ranges from 540V/µs (OPA2683IDR, OPA2683ID) to 4000V/µs (EL5263ISZ-T7). Bandwidth ranges from 200 MHz (OPA2683IDR, OPA2683ID) to 500 MHz (EL5263ISZ-T7). Output current per channel ranges from 100 mA (EL5263ISZ-T7) to 150 mA (OPA2683IDR, OPA2683ID). Input bias current ranges from 2 µA (LMH6724MA/NOPB, LMH6724MAX/NOPB, EL5263ISZ-T7) to 3 µA (OPA2683IDR, OPA2683ID). All devices maintain identical operating temperature range (-40°C to 85°C) and 8-SOIC package form factor.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. OPA2683IDR, OPA2683ID, and EL5263ISZ-T7 are explicitly ROHS3 compliant. Compliance status for LMH6724MA/NOPB and LMH6724MAX/NOPB is not specified in the provided data; verification with National Semiconductor documentation is recommended for applications with strict RoHS compliance requirements.

Q: What is the minimum supply voltage for each substitute?

A: OPA2683IDR, OPA2683ID, and EL5263ISZ-T7 require minimum 5V supply. LMH6724MA/NOPB and LMH6724MAX/NOPB operate at minimum 4.5V, providing broader supply compatibility. Maximum supply voltage is 12V across all devices.

Q: Which substitute offers the best performance for high-speed applications?

A: The EL5263ISZ-T7 provides the highest slew rate (4000V/µs) and bandwidth (500 MHz), making it optimal for high-speed signal conditioning. However, output current per channel is limited to 100 mA. The LMH6724MA/NOPB and LMH6724MAX/NOPB offer balanced performance with 600V/µs slew rate and 370 MHz bandwidth while maintaining 110 mA output current per channel and Active product status.
