Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX474EPA is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of circuits: 2 (dual-channel requirement)
• Output type: Rail-to-rail capability
• Package: 8-DIP (0.300", 7.62mm) through-hole configuration
• Mounting type: Through hole

Secondary Compatibility Criteria:

• Voltage supply span overlap with original specification (2.7 V to 5.25 V)
• Operating temperature range compatibility
• Pin-compatible 8-PDIP package footprint

The substitute parts listed below maintain the core functional requirements of dual-channel, rail-to-rail amplification in identical 8-DIP packaging. Variations in slew rate, gain bandwidth product, input bias current, and supply current are acceptable within the general-purpose amplifier category, provided the substitute operates within the specified voltage and temperature ranges of the application.

Engineering Selection Recommendations

MCP6292-E/P (Microchip Technology)

The MCP6292-E/P is an active product with ROHS3 compliance, offering the most direct functional replacement for the obsolete MAX474EPA. This device maintains dual-channel, rail-to-rail architecture in identical 8-DIP packaging. The MCP6292-E/P operates across an extended voltage range (2.4 V to 6 V) and supports the full industrial temperature range (-40°C to 125°C). Supply current is reduced to 1 mA per channel pair, providing improved power efficiency. Input bias current is significantly lower at 1 pA, beneficial for high-impedance applications. The slew rate of 7 V/µs and gain bandwidth product of 10 MHz remain suitable for general-purpose amplification. This part is recommended for new designs and production continuity where RoHS compliance is required.

TLV2772AIP (Texas Instruments)

The TLV2772AIP is classified as Last Time Buy with ROHS3 compliance. This CMOS amplifier provides dual-channel, rail-to-rail output in 8-DIP packaging with extended temperature range support (-40°C to 125°C). The device features 2 pA input bias current and 500 µV input offset voltage. Slew rate is 10.5 V/µs with 5.1 MHz gain bandwidth product. Supply current is 1 mA per channel pair. The TLV2772AIP is suitable for applications where CMOS technology and lower input bias current are advantageous. Last Time Buy status indicates limited future availability.

TLV2772IP (Texas Instruments)

The TLV2772IP is functionally identical to the TLV2772AIP with the same electrical specifications and ROHS3 compliance. It supports the full industrial temperature range (-40°C to 125°C) and is classified as Last Time Buy. This part is interchangeable with TLV2772AIP for applications requiring extended temperature operation.

TLV2772CP (Texas Instruments)

The TLV2772CP is a commercial-grade variant of the TLV2772 series with operating temperature range limited to 0°C to 70°C. This part is classified as Last Time Buy with ROHS3 compliance. The TLV2772CP is suitable only for applications operating within the commercial temperature range and should not be selected for designs requiring the full industrial temperature range of the MAX474EPA.

Frequently Asked Questions (FAQ)

Q: Can the MCP6292-E/P directly replace the MAX474EPA in existing designs?

A: Yes. The MCP6292-E/P maintains pin-compatible 8-DIP packaging, dual-channel configuration, and rail-to-rail output capability. Both devices operate within overlapping voltage ranges (2.7 V to 5.25 V for MAX474EPA; 2.4 V to 6 V for MCP6292-E/P). The MCP6292-E/P supports extended temperature range (-40°C to 125°C) and is RoHS3 compliant, making it suitable for direct substitution in applications operating within the original temperature specification.

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

A: All three variants are CMOS amplifiers with identical electrical specifications (10.5 V/µs slew rate, 5.1 MHz gain bandwidth product, 2 pA input bias current). The primary difference is operating temperature range: TLV2772AIP and TLV2772IP support -40°C to 125°C (industrial range), while TLV2772CP is limited to 0°C to 70°C (commercial range). All three are RoHS3 compliant and available in 8-DIP packaging.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. All substitute parts listed (MCP6292-E/P, TLV2772AIP, TLV2772CP, TLV2772IP) are packaged in 8-DIP (0.300", 7.62mm) through-hole configuration, identical to the MAX474EPA. Pin-to-pin compatibility is maintained for direct board-level substitution.

Q: What is the significance of "Last Time Buy" status for the TLV2772 series?

A: Last Time Buy status indicates that Texas Instruments has announced end-of-life for these products. Inventory is limited and will not be replenished after current stock is depleted. For long-term production requirements, the MCP6292-E/P (Active status) is the recommended choice.

Q: How do the electrical specifications of substitute parts compare to the MAX474EPA?

A: The MAX474EPA features higher slew rate (17 V/µs) and gain bandwidth product (12 MHz) compared to all substitutes. However, all substitutes maintain rail-to-rail output and dual-channel configuration. The MCP6292-E/P offers the closest performance match with 7 V/µs slew rate and 10 MHz gain bandwidth product. The TLV2772 series provides lower input bias current (2 pA) and reduced supply current (1 mA per channel pair), beneficial for low-power applications.

Q: Is RoHS compliance a factor in selecting a substitute?

A: Yes. The MAX474EPA is RoHS non-compliant. All substitute parts (MCP6292-E/P, TLV2772AIP, TLV2772CP, TLV2772IP) are ROHS3 compliant. For designs subject to RoHS regulations or customer requirements, any of the listed substitutes is acceptable. For designs without RoHS requirements, the MAX474EPA can still be used if inventory is available.

Q: Can the TLV2772CP be used in applications requiring -40°C operation?

A: No. The TLV2772CP is rated for 0°C to 70°C operation only. Applications requiring -40°C to 85°C operation must use either the MCP6292-E/P, TLV2772AIP, or TLV2772IP, all of which support -40°C minimum operating temperature.
