Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LT1364CS8#TRPBF are selected based on the following criteria:

Primary Substitution Criteria:

• Amplifier topology: Voltage Feedback
• Circuit count: 2 independent circuits
• Package type: 8-SOIC surface mount with 0.154" (3.90mm) width
• Supply voltage range compatibility: Minimum 5V to maximum 36V overlap
• Operating temperature range: Minimum 0°C operation required

Secondary Compatibility Parameters:

• Slew rate: 1000 V/µs or greater
• Gain bandwidth product: 70 MHz or greater
• Input bias current: 600 nA or less
• Input offset voltage: 500 µV or less
• Output current per channel: 60 mA or greater
• Supply current: 6.3 mA (x2 Channels) or less

Substitutes are grouped into two categories: direct replacements with identical or superior electrical performance, and functional alternatives with trade-offs in specific parameters. Parts listed maintain the same package footprint and pinout compatibility, enabling direct PCB substitution without layout modification.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status Substitutes:

The ADA4898-2YRDZ-R7 and OPA2277MDTEP are the only substitute parts with active product status. The ADA4898-2YRDZ-R7 maintains voltage feedback topology and dual-circuit configuration with superior input offset voltage (20 µV vs. 500 µV) and lower input bias current (100 nA vs. 600 nA). However, it exhibits reduced slew rate (55 V/µs vs. 1000 V/µs) and lower gain bandwidth product (50 MHz vs. 70 MHz). The ADA4898-2YRDZ-R7 requires minimum 9V supply voltage, restricting use in 5V applications. The OPA2277MDTEP is a general-purpose amplifier with significantly different performance characteristics, including 1 MHz bandwidth and 0.8 V/µs slew rate, suitable only for low-frequency applications.

Obsolete and End-of-Life Substitutes:

The LM6172IM, THS4032CD, and THS4032ID are classified as obsolete or last-time-buy products. The LM6172IM offers superior slew rate (3000 V/µs) and bandwidth (100 MHz) with extended supply range compatibility (5.5V to 36V). The THS4032CD and THS4032ID provide 120 MHz gain bandwidth product but require minimum 9V supply voltage and are no longer in active production.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification, matching the original LT1364CS8#TRPBF regulatory status. Moisture sensitivity levels vary: ADA4898-2YRDZ-R7 and OPA2277MDTEP require MSL 3 handling (168 hours), while LM6172IM and THS4032 variants maintain MSL 1 (unlimited) classification.

Supply Voltage Compatibility:

The LT1364CS8#TRPBF operates from 5V to 36V. Substitutes with identical minimum supply voltage (5V) are LM6172IM and OPA2277MDTEP. The ADA4898-2YRDZ-R7 and THS4032 variants require minimum 9V supply, eliminating compatibility with 5V single-supply applications.

Frequently Asked Questions (FAQ)

Q: Can the ADA4898-2YRDZ-R7 directly replace the LT1364CS8#TRPBF in all applications?

A: The ADA4898-2YRDZ-R7 is pin-compatible and maintains voltage feedback topology with dual circuits. However, it requires minimum 9V supply voltage, making it unsuitable for 5V applications. The reduced slew rate (55 V/µs vs. 1000 V/µs) and lower gain bandwidth product (50 MHz vs. 70 MHz) may affect high-speed signal conditioning circuits. Verify supply voltage requirements and bandwidth specifications before substitution.

Q: What is the difference between ADA4898-2YRDZ and ADA4898-2YRDZ-R7?

A: Both parts are identical in electrical specifications and package type (8-SOIC-EP). The primary difference is packaging format: ADA4898-2YRDZ is supplied in tube packaging, while ADA4898-2YRDZ-R7 is supplied in cut tape (CT) and Digi-Reel format. Selection depends on assembly process requirements and tape-and-reel compatibility with pick-and-place equipment.

Q: Why is the LM6172IM listed as obsolete?

A: The LM6172IM is classified as obsolete by Texas Instruments and is no longer in active production. While inventory remains available, long-term supply cannot be guaranteed. For new designs, active-status alternatives such as ADA4898-2YRDZ-R7 or OPA2277MDTEP are recommended.

Q: Can the OPA2277MDTEP replace the LT1364CS8#TRPBF?

A: The OPA2277MDTEP is a general-purpose amplifier with fundamentally different performance characteristics. Its 1 MHz gain bandwidth product and 0.8 V/µs slew rate are suitable only for low-frequency applications. It is not a functional substitute for the LT1364CS8#TRPBF in circuits requiring 70 MHz bandwidth or 1000 V/µs slew rate performance.

Q: What are the package differences between standard 8-SOIC and 8-SOIC-EP?

A: The 8-SOIC-EP (Exposed Pad) variant includes an additional thermal pad on the package underside for improved heat dissipation. Both maintain identical 0.154" (3.90mm) width and pinout. The ADA4898-2YRDZ-R7 uses 8-SOIC-EP packaging, while the LT1364CS8#TRPBF uses standard 8-SOIC. PCB layout modifications may be required to utilize the exposed pad thermal connection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance status, matching the original LT1364CS8#TRPBF regulatory requirement. REACH status is unaffected for all parts except LM6172IM, which is REACH affected.

Q: What is the moisture sensitivity level (MSL) impact on handling and storage?

A: The LT1364CS8#TRPBF and LM6172IM maintain MSL 1 (unlimited) classification, permitting indefinite storage without moisture baking. The ADA4898-2YRDZ-R7 and OPA2277MDTEP require MSL 3 (168 hours) handling, necessitating moisture baking before reflow soldering if storage exceeds 168 hours in standard humidity conditions.

Q: Which substitute offers the best input offset voltage performance?

A: The ADA4898-2YRDZ-R7 and OPA2277MDTEP both provide 20 µV input offset voltage, compared to 500 µV for the LT1364CS8#TRPBF. This represents 25-fold improvement in offset voltage accuracy, beneficial for precision instrumentation and low-level signal conditioning applications.

Q: Can THS4032 variants be used in new designs?

A: The THS4032CD is classified as obsolete, and THS4032ID is designated last-time-buy. Both are no longer recommended for new designs. Existing designs using these parts should transition to active-status alternatives such as ADA4898-2YRDZ-R7 to ensure long-term supply continuity.
