Engineering Selection Recommendations

Direct Replacement:

OP497GSZ is the recommended direct replacement for OP497GS. Both parts maintain identical electrical specifications across all measured parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range. Both support the full industrial temperature range of -40°C to 85°C. The primary difference is product status: OP497GSZ is Active, ensuring long-term availability and supply chain continuity. OP497GSZ is available in Tube packaging format and carries ROHS3 compliance and REACH Unaffected status.

Alternative Selection When Electrical Deviations Are Acceptable:

LT1058ISW, LT1058ISW#PBF, and LT1058ISW#TRPBF are J-FET amplifier alternatives that maintain the 4-circuit configuration and 16-SOIC package footprint. These parts feature significantly higher slew rate (13V/µs versus 0.15V/µs), higher gain bandwidth product (5 MHz versus 500 kHz), and lower input bias current (10 pA versus 60 pA). However, they require minimum supply voltage of 20V and maximum of 36V, which differs from the OP497GS range of 4V to 40V. LT1058ISW and LT1058ISW#PBF support -40°C to 85°C operation, while LT1058SW#PBF and LT1058SW#TRPBF are limited to 0°C to 70°C. All LT1058 variants are Active products with ROHS3 compliance.

LT1114IS and LT1114S are general purpose alternatives with improved slew rate (0.3V/µs) and gain bandwidth product (750 kHz) compared to OP497GS. These parts feature lower supply current (350µA versus 525µA) and support lower minimum supply voltage (2V versus 4V). However, the package width differs (0.154" versus 0.295"), which may impact PCB layout compatibility. LT1114IS supports -40°C to 85°C operation, while LT1114S is limited to 0°C to 70°C. Both are Active products with ROHS3 compliance.

LT1125CSW and LT1125CSW#PBF offer the highest performance among alternatives, with slew rate of 4.5V/µs and gain bandwidth product of 12.5 MHz. These parts maintain the 0.295" package width matching OP497GS. However, they require minimum supply voltage of 8V and are limited to 0°C to 70°C operation. Both are Active products with ROHS3 compliance.

The 16-SOIC package footprint is identical. No circuit modification is required.

Q: What is the primary reason to transition from OP497GS to OP497GSZ?

A: OP497GS is classified as obsolete, while OP497GSZ is Active. Transitioning to OP497GSZ ensures long-term availability, supply chain continuity, and compliance with modern manufacturing standards. OP497GSZ carries ROHS3 compliance and REACH Unaffected status.

Q: Can LT1058ISW replace OP497GS in all applications?

A: LT1058ISW shares the 4-circuit configuration and 16-SOIC package but differs significantly in electrical characteristics. LT1058ISW is a J-FET amplifier with 13V/µs slew rate and 5 MHz gain bandwidth product, compared to OP497GS general purpose design with 0.15V/µs slew rate and 500 kHz gain bandwidth product. Additionally, LT1058ISW requires minimum supply voltage of 20V, while OP497GS operates from 4V. Substitution is only appropriate when application requirements permit these electrical deviations.

Q: What is the difference between LT1058ISW and LT1058SW#PBF?

A: Both are J-FET amplifiers with identical electrical specifications. The primary difference is operating temperature range: LT1058ISW supports -40°C to 85°C (industrial range), while LT1058SW#PBF is limited to 0°C to 70°C (commercial range). Select LT1058ISW for applications requiring full industrial temperature operation.

Q: Are LT1114IS and LT1114S pin-compatible with OP497GS?

A: Both LT1114IS and LT1114S use 16-SOIC packaging and maintain the same pin count. However, the package width differs: LT1114 series uses 0.154" width while OP497GS uses 0.295" width. This difference may affect PCB layout compatibility and socket fit. Verify mechanical compatibility before substitution.

Q: What packaging options are available for OP497GSZ?

A: OP497GSZ is available in Tube packaging format. The original OP497GS packaging format is not specified in the provided data.
