Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

The OP496GSZ-REEL is the recommended primary substitute for the OP496GS-REEL. This part maintains identical electrical specifications, package configuration, and operating parameters while offering active product status and ROHS3 compliance. The OP496GSZ-REEL differs only in packaging format (Cut Tape & Digi-Reel® versus reel configuration) and product status, making it a direct functional replacement with superior supply chain availability.

Alternative Substitutes (Performance-Dependent Selection):

The LMP7704MA/NOPB and LMP7704MAX/NOPB from Texas Instruments provide functional equivalence with enhanced input bias current performance (0.2 pA versus 10 nA) and extended supply voltage range (2.7V minimum). These devices are suitable for applications requiring lower input bias current characteristics while maintaining the 14-SOIC package format and rail-to-rail output configuration.

The LM6584MA/NOPB and LM6584MAX/NOPB offer significantly higher slew rate (15V/µs) and gain bandwidth product (24 MHz) compared to the OP496GS-REEL, making them appropriate for applications requiring enhanced frequency response and transient performance. These devices operate within the specified supply voltage range and maintain the 14-SOIC package format.

The TS934AIYDT from STMicroelectronics provides a low-power alternative with automotive-grade qualification (AEC-Q100) and reduced supply current consumption (20µA per 4 channels). This device operates within a maximum supply voltage of 10V and maximum operating temperature of 105°C, requiring verification against application temperature requirements.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and surface mount 14-SOIC package compatibility, ensuring PCB assembly process compatibility with the original OP496GS-REEL design.

Frequently Asked Questions (FAQ)

Q: Can the OP496GSZ-REEL directly replace the OP496GS-REEL in existing designs?

A: Yes. The OP496GSZ-REEL is electrically and functionally identical to the OP496GS-REEL, with matching specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, output current per channel, and supply voltage range. The only differences are packaging format and active product status. PCB layout and schematic connections require no modification.

Q: What are the key differences between the OP496GS-REEL and the LMP7704 series?

A: The LMP7704MA/NOPB and LMP7704MAX/NOPB offer superior input bias current performance (0.2 pA versus 10 nA) and lower minimum supply voltage (2.7V versus 3V). However, they exhibit lower slew rate (1.1V/µs versus 0.3V/µs) and higher gain bandwidth product (2.5 MHz versus 450 kHz). All devices share the 14-SOIC package format and rail-to-rail output configuration. Selection depends on application requirements for input bias current and frequency response characteristics.

Q: Are the LM6584 series substitutes suitable for high-frequency applications?

A: The LM6584MA/NOPB and LM6584MAX/NOPB provide significantly higher slew rate (15V/µs) and gain bandwidth product (24 MHz) compared to the OP496GS-REEL. These characteristics make them suitable for applications requiring enhanced transient response and frequency response. However, they deliver higher output current per channel (75 mA versus 4 mA) and higher supply current consumption (780 µA versus unspecified), which may impact power budget considerations.

Q: What is the operating temperature limitation of the TS934AIYDT?

A: The TS934AIYDT operates across a temperature range of -40°C to 105°C, compared to the OP496GS-REEL range of -40°C to 125°C. Applications requiring operation above 105°C are not compatible with this substitute. The TS934AIYDT is qualified to AEC-Q100 automotive standards and offers reduced supply current consumption (20µA per 4 channels).

Q: Do all substitute parts maintain the same 14-SOIC package footprint?

A: Yes. All substitute parts listed (OP496GSZ-REEL, LMP7704MA/NOPB, LMP7704MAX/NOPB, LM6584MA/NOPB, LM6584MAX/NOPB, and TS934AIYDT) are packaged in 14-SOIC (0.154", 3.90mm Width) format with surface mount configuration. PCB footprints and assembly processes are compatible without modification.

Q: What is the maximum supply voltage for the TS934AIYDT?

A: The TS934AIYDT operates with a maximum supply voltage of 10V, compared to 12V for the OP496GS-REEL. Applications requiring operation at 12V supply voltage are not compatible with this substitute. Verification of application supply voltage requirements is necessary before selection.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed (OP496GSZ-REEL, LMP7704MA/NOPB, LMP7704MAX/NOPB, LM6584MA/NOPB, LM6584MAX/NOPB, and TS934AIYDT) are ROHS3 compliant. The original OP496GS-REEL is classified as obsolete and does not carry ROHS3 certification. Compliance with ROHS3 requirements necessitates transition to an active substitute part.

Q: What is the input bias current difference between the OP496GS-REEL and LMP7704 series?

A: The OP496GS-REEL exhibits an input bias current of 10 nA, while the LMP7704MA/NOPB and LMP7704MAX/NOPB specify 0.2 pA. This represents a 50,000-fold reduction in input bias current. Applications sensitive to input bias current effects benefit from the LMP7704 series, while applications with less stringent input bias current requirements can utilize either device.

Q: Can the LM6584 series be used in low-power applications?

A: The LM6584MA/NOPB and LM6584MAX/NOPB consume 780 µA supply current, compared to unspecified consumption for the OP496GS-REEL. These devices deliver higher output current per channel (75 mA versus 4 mA) and exhibit higher slew rate (15V/µs versus 0.3V/µs), making them optimized for higher-performance applications rather than low-power implementations. Applications with strict power consumption budgets should evaluate the OP496GSZ-REEL or TS934AIYDT as alternatives.
