Parameter Comparison

Engineering Selection Recommendations

The OPA726AID is the direct substitute for the obsolete OPA726AIDRG4. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product status: OPA726AIDRG4 is obsolete, while OPA726AID maintains active status with Texas Instruments.

Selection of OPA726AID ensures:

• Full electrical parameter equivalence across all specified ranges
• Identical 8-SOIC surface mount package compatibility
• Continued compliance with ROHS3 and REACH requirements
• Active product support and procurement availability
• Equivalent moisture sensitivity classification (MSL 2)

The substitute part is suitable for direct replacement in existing designs without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can OPA726AID directly replace OPA726AIDRG4 in existing PCB designs?

A: Yes. Both components feature identical electrical parameters, output type (rail-to-rail), slew rate (30 V/µs), gain bandwidth product (20 MHz), and 8-SOIC package dimensions. No circuit redesign is required.

Q: What is the difference between OPA726AIDRG4 and OPA726AID?

A: The components are electrically and mechanically identical. The primary difference is product status: OPA726AIDRG4 is obsolete, while OPA726AID is active. The packaging differs (OPA726AIDRG4 uses tape/reel; OPA726AID uses tube), but the die and electrical performance are equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 2, 1 Year). Regulatory and environmental certifications are equivalent.

Q: What supply voltage range does this amplifier support?

A: Both OPA726AIDRG4 and OPA726AID operate across a 4 V to 12 V supply span, supporting single or dual supply configurations within this range.

Q: Is the 8-SOIC package footprint identical between both parts?

A: Yes. Both components use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints and land patterns are identical.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 125°C, suitable for industrial and commercial temperature environments.

Q: Can I use OPA726AID in new designs?

A: Yes. OPA726AID is the active equivalent and is suitable for new design implementations. It provides the same electrical performance and package compatibility as the obsolete OPA726AIDRG4.
