• Mounting type: Surface Mount
• Amplifier type: General Purpose
• Output type: Rail-to-Rail
• Number of circuits: 1
• Supply voltage range compatibility: Minimum 1.8 V, Maximum 5.5 V

Secondary Compatibility Factors:

• Operating temperature range (application-dependent)
• Slew rate and gain bandwidth product (performance-dependent)
• Input bias current and input offset voltage (precision-dependent)
• Supply current and output current capabilities (power budget-dependent)

The substitute parts identified below share the identical package footprint and basic functional classification. Electrical performance characteristics vary and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

LMP7717MAE/NOPB (Direct Equivalent)

The LMP7717MAE/NOPB is the direct active equivalent of the obsolete LMP7717MAE. Both devices are manufactured by Texas Instruments and share identical electrical specifications, including 88 MHz gain bandwidth product, 35 V/µs slew rate, and 60 mA output current capability. The primary distinction is product status: LMP7717MAE/NOPB is active and ROHS3 compliant, whereas the original LMP7717MAE is obsolete and RoHS non-compliant. This part is the preferred replacement for direct substitution in new designs and production continuity.

MAX4289ESA+ and MAX4289ESA+T (Functional Alternatives)

The MAX4289ESA+ and MAX4289ESA+T, manufactured by Analog Devices Inc./Maxim Integrated, are functionally compatible alternatives. Both devices maintain the 8-SOIC package footprint and rail-to-rail output configuration. However, these parts exhibit significantly lower performance specifications: 17 kHz gain bandwidth product and 0.006 V/µs slew rate compared to the LMP7717MAE's 88 MHz and 35 V/µs. These devices are suitable for applications where high-speed performance is not required. Both are ROHS3 compliant and active. The MAX4289ESA+T variant is supplied in Tape & Reel packaging, while MAX4289ESA+ is supplied in Tube packaging.

RE46C311S8F (Low-Power Alternative)

The RE46C311S8F, manufactured by Microchip Technology, offers the lowest supply current consumption at 600 nA, compared to 1.15 mA for the LMP7717MAE. This device is suitable for ultra-low-power applications. However, it exhibits the lowest performance metrics: 10 kHz gain bandwidth product, 0.003 V/µs slew rate, and 3 mV input offset voltage. The operating temperature range is restricted to -10°C to 60°C, which is narrower than the LMP7717MAE's -40°C to 125°C range. This part is ROHS3 compliant and active.

Compliance and Regulatory Status

All substitute parts identified are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original LMP7717MAE is RoHS non-compliant and obsolete. For new production and designs subject to RoHS requirements, LMP7717MAE/NOPB is the mandatory replacement.

Frequently Asked Questions (FAQ)

Q: Can I directly replace LMP7717MAE with LMP7717MAE/NOPB without circuit modifications?

A: Yes. The LMP7717MAE/NOPB is the direct active equivalent with identical electrical specifications and package footprint. No circuit modifications are required. The primary difference is product status and RoHS compliance.

Q: What are the key differences between LMP7717MAE and MAX4289ESA+?

A: Both devices share the 8-SOIC package and rail-to-rail output configuration. The LMP7717MAE provides 88 MHz gain bandwidth product and 35 V/µs slew rate, while the MAX4289ESA+ provides 17 kHz gain bandwidth product and 0.006 V/µs slew rate. The LMP7717MAE is suitable for high-speed applications, while the MAX4289ESA+ is suitable for low-frequency, low-power applications. The MAX4289ESA+ also exhibits higher input offset voltage (200 µV vs. 10 µV) and higher input bias current (5 nA vs. 0.1 pA).

Q: Is RE46C311S8F suitable for high-speed signal processing?

A: No. The RE46C311S8F has a gain bandwidth product of 10 kHz and slew rate of 0.003 V/µs, making it unsuitable for high-speed applications. This device is optimized for ultra-low-power, low-frequency applications. Additionally, its operating temperature range (-10°C to 60°C) is narrower than the LMP7717MAE.

Q: What is the difference between MAX4289ESA+ and MAX4289ESA+T?

A: Both devices have identical electrical specifications. The difference is packaging: MAX4289ESA+ is supplied in Tube packaging, while MAX4289ESA+T is supplied in Tape & Reel (TR) packaging. Selection depends on production volume and assembly process requirements.

Q: Are all substitute parts available in the same package footprint?

A: Yes. All identified substitute parts use the 8-SOIC (0.154", 3.90mm Width) package, ensuring PCB footprint compatibility. All are surface mount devices.

Q: Which substitute part should I select for a new design requiring RoHS compliance?

A: All substitute parts identified (LMP7717MAE/NOPB, MAX4289ESA+, MAX4289ESA+T, and RE46C311S8F) are ROHS3 compliant. Selection should be based on electrical performance requirements. For performance equivalent to the original LMP7717MAE, use LMP7717MAE/NOPB.

Q: What is the operating temperature range limitation for RE46C311S8F?

A: The RE46C311S8F operates from -10°C to 60°C, which is narrower than the LMP7717MAE's -40°C to 125°C range. Applications requiring operation below -10°C or above 60°C cannot use this device.

Q: Can I use MAX4289ESA+ in a circuit designed for LMP7717MAE?

A: Electrical compatibility depends on application requirements. The MAX4289ESA+ has lower gain bandwidth product (17 kHz vs. 88 MHz) and lower slew rate (0.006 V/µs vs. 35 V/µs). If the circuit requires high-speed performance, the MAX4289ESA+ is not suitable. If the circuit operates at low frequencies, the MAX4289ESA+ may function, but circuit performance will differ due to lower bandwidth and higher input offset voltage.

Q: What is the moisture sensitivity level for all parts?

A: All identified parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
