Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The OP496GSZ is the direct equivalent of the OP496GS, manufactured by Analog Devices Inc. This part maintains identical electrical specifications and package configuration. The OP496GSZ is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Selection of OP496GSZ is appropriate for direct replacement in existing designs without circuit modification.

Active Substitute Parts (Functional Compatibility):

The following parts are active products suitable for substitution based on parameter alignment:

LMP7704MA/NOPB and LMP7704MAX/NOPB (Texas Instruments): These general-purpose amplifiers provide rail-to-rail output in 14-SOIC packaging with enhanced input bias current performance (0.2 pA). Both parts are ROHS3 compliant and operate across the required temperature range. The LMP7704 series exhibits higher slew rate (1.1V/µs) and gain bandwidth product (2.5 MHz) compared to the OP496GS, making them suitable for applications requiring improved frequency response.

LMP7709MA/NOPB and LMP7709MAX/NOPB (Texas Instruments): These general-purpose amplifiers offer superior performance characteristics with slew rate of 5.9V/µs and gain bandwidth product of 15 MHz. Both maintain rail-to-rail output, 14-SOIC packaging, and full temperature range operation. ROHS3 compliance is confirmed. The LMP7709 series is appropriate for designs requiring higher bandwidth performance within the same package footprint.

LM6584MA/NOPB and LM6584MAX/NOPB (Texas Instruments): These video amplifiers provide four circuits in 14-SOIC packaging with significantly enhanced output current capability (75 mA per channel). Slew rate is 15V/µs and gain bandwidth product is 24 MHz. Both parts are ROHS3 compliant. The LM6584 series is suitable for applications requiring higher output drive capability and bandwidth performance.

Frequently Asked Questions (FAQ)

Q: Can OP496GSZ be used as a direct replacement for OP496GS?

A: Yes. The OP496GSZ is manufactured by Analog Devices Inc. and maintains identical electrical specifications, package configuration, and operating parameters as the OP496GS. The primary difference is product status: OP496GSZ is active while OP496GS is obsolete. No circuit modifications are required for substitution.

Q: What is the key difference between the LMP7704 and LMP7709 series?

A: Both series are four-circuit rail-to-rail amplifiers in 14-SOIC packaging. The LMP7709 series provides higher performance with slew rate of 5.9V/µs and gain bandwidth product of 15 MHz, compared to the LMP7704 series at 1.1V/µs and 2.5 MHz respectively. Selection depends on application bandwidth requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed (OP496GSZ, LMP7704MA/NOPB, LMP7704MAX/NOPB, LMP7709MA/NOPB, LM6584MA/NOPB, LM6584MAX/NOPB, and TS934AIYDT) are ROHS3 compliant. The original OP496GS does not specify RoHS status.

Q: What is the operating temperature limitation of TS934AIYDT?

A: The TS934AIYDT operates from -40°C to 105°C, which is narrower than the OP496GS range of -40°C to 125°C. Applications requiring operation above 105°C must use alternative substitutes.

Q: Why does LM6584 have higher output current capability?

A: The LM6584 series is designed for video amplifier applications and provides 75 mA output current per channel compared to 4 mA for the OP496GS. This higher drive capability makes the LM6584 suitable for applications requiring greater output current, though it is not required for direct replacement in low-current designs.

Q: Can TS934AIYDT be used in all OP496GS applications?

A: The TS934AIYDT meets the core substitution criteria of four circuits, rail-to-rail output, and 14-SOIC packaging. However, its lower slew rate (0.05V/µs) and gain bandwidth product (100 kHz) make it unsuitable for applications requiring the OP496GS performance level. Verify application bandwidth and slew rate requirements before selection.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (MA/NOPB variants), Tape & Reel (MAX/NOPB variants), Cut Tape & Digi-Reel (TS934AIYDT), and Bulk (LMP7709MAX/NOPB). Select packaging based on procurement and assembly requirements.

Q: Are all substitute parts available in the same 14-SOIC package dimensions?

A: Yes. All substitute parts are specified for 14-SOIC (0.154", 3.90mm Width) package configuration, ensuring mechanical compatibility with existing PCB layouts and assembly processes.
