Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX474CPA+ is determined by the following critical parameters:

Primary Compatibility Criteria:

• Dual-circuit operational amplifier configuration (2 circuits per package)
• 8-PDIP through-hole package format (0.300", 7.62mm)
• Rail-to-rail output capability
• Supply voltage range overlap with 2.7 V minimum and 5.25 V maximum
• Operating temperature range compatibility

Substitution Logic: The three substitute parts (MCP6292-E/P, TLV2772AIP, TLV2772CP, TLV2772IP) share identical package geometry and pinout compatibility with the MAX474CPA+. All substitutes maintain rail-to-rail output architecture and dual-circuit topology. Supply voltage ranges of substitute parts encompass or overlap the MAX474CPA+ operating window. Operating temperature ranges vary among substitutes; TLV2772CP matches the original temperature specification (0°C ~ 70°C), while MCP6292-E/P and TLV2772AIP/IP extend to -40°C ~ 125°C.

Parameter Comparison

Engineering Selection Recommendations

MCP6292-E/P (Microchip Technology): This substitute is the only actively produced alternative among the listed options. It provides extended operating temperature range (-40°C ~ 125°C) and maintains ROHS3 compliance. The MCP6292-E/P features lower input bias current (1 pA) and reduced supply current (1 mA per channel) compared to the MAX474CPA+, resulting in improved power efficiency. However, slew rate and gain bandwidth product are reduced relative to the original device. This part is suitable for applications where power consumption reduction and extended temperature operation are beneficial.

TLV2772AIP (Texas Instruments): This CMOS amplifier operates across -40°C ~ 125°C and carries Last Time Buy status. It offers the lowest input bias current (2 pA) and reduced supply current. The TLV2772AIP is appropriate for designs requiring extended temperature performance and minimal input bias current characteristics. Last Time Buy status indicates limited future availability.

TLV2772CP (Texas Instruments): This variant matches the original MAX474CPA+ operating temperature range (0°C ~ 70°C) exactly, making it the most direct thermal substitute. It maintains ROHS3 compliance and Last Time Buy status. The TLV2772CP is optimal for applications with temperature specifications identical to the original design.

TLV2772IP (Texas Instruments): This part extends operating temperature to -40°C ~ 125°C while maintaining the same electrical characteristics as TLV2772AIP and TLV2772CP. It carries Last Time Buy status and is suitable for designs requiring extended temperature operation beyond the original specification.

All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the MAX474CPA+.

Frequently Asked Questions (FAQ)

Q: Can the MCP6292-E/P directly replace the MAX474CPA+ in existing designs?

A: Yes, the MCP6292-E/P is pin-compatible and shares the same 8-PDIP package geometry. However, electrical performance differs: slew rate is reduced from 17 V/µs to 7 V/µs, and gain bandwidth product decreases from 12 MHz to 10 MHz. Circuit performance must be verified for applications sensitive to these parameters.

Q: What is the difference between TLV2772AIP, TLV2772CP, and TLV2772IP?

A: These three parts are electrically identical but differ in operating temperature range. TLV2772CP operates 0°C ~ 70°C (matching MAX474CPA+), while TLV2772AIP and TLV2772IP both operate -40°C ~ 125°C. All three carry Last Time Buy status from Texas Instruments.

Q: Why do substitute parts have lower slew rates and gain bandwidth products?

A: The substitute parts represent different design generations and technology nodes. Lower slew rates and bandwidth products reflect design trade-offs favoring reduced power consumption and input bias current. Applications requiring the original performance specifications may not be suitable for these substitutes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (MCP6292-E/P, TLV2772AIP, TLV2772CP, TLV2772IP) are ROHS3 compliant, matching the regulatory status of the MAX474CPA+.

Q: Which substitute has the best long-term availability?

A: The MCP6292-E/P is the only actively produced part among the substitutes. TLV2772AIP, TLV2772CP, and TLV2772IP all carry Last Time Buy status, indicating limited future availability. For new designs requiring long-term supply assurance, MCP6292-E/P is the recommended choice.

Q: Can I use TLV2772CP in applications requiring -40°C operation?

A: No, TLV2772CP is rated only to 0°C minimum. For applications requiring -40°C operation, use TLV2772AIP or TLV2772IP instead.

Q: What is the impact of lower input bias current in substitute parts?

A: Lower input bias current (1-2 pA versus 80 nA in MAX474CPA+) reduces input offset drift and improves precision in high-impedance circuits. This is generally beneficial for most applications.
