MAX4166EUA+ Equivalent & Substitute Parts

Part Overview

The MAX4166EUA+ is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for rail-to-rail applications in 8-uMAX/uSOP surface mount packaging. This single-circuit amplifier operates across a 2.7V to 6.5V supply range with a 5 MHz gain bandwidth product and 2V/µs slew rate, suitable for low-power signal conditioning and general analog processing applications.

The MAX4166EUA+ maintains active product status with 5100 units in stock. Substitute parts are identified based on functional equivalence within the general-purpose amplifier category, matching critical electrical parameters and package compatibility requirements for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4166EUA+ is determined by functional equivalence across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type classification (General Purpose)
• Single-circuit configuration
• Rail-to-rail output capability
• Supply voltage range overlap (minimum 2.7V to 6.5V compatibility)
• Operating temperature range coverage (-40°C to 85°C minimum)

Mechanical Compatibility Criteria:

• Surface mount technology
• 8-pin package format (TSSOP or MSOP variants)
• Pin-compatible footprint dimensions

Regulatory & Quality Criteria:

• ROHS3 compliance
• MSL Level 1 rating
• Active or automotive-qualified product status

The substitute parts identified—TLV2460AQPWRG4Q1, TLV2460QPWG4, and TLV2460QPWRG4Q1—meet these criteria with electrical performance within acceptable operational boundaries for general-purpose amplifier applications.

Engineering Selection Recommendations

Primary Substitute: TLV2460QPWRG4Q1

The TLV2460QPWRG4Q1 is the recommended substitute for the MAX4166EUA+. This part maintains active product status with 1036 units in inventory and carries AEC-Q100 automotive qualification. The TLV2460QPWRG4Q1 provides extended operating temperature range (-40°C to 125°C) compared to the MAX4166EUA+ (-40°C to 85°C), offering broader thermal coverage. Both devices are ROHS3 compliant with MSL Level 1 ratings.

Electrical performance differences are within acceptable operational boundaries: the TLV2460QPWRG4Q1 exhibits lower input bias current (1.3 nA vs. 50 nA), higher gain bandwidth product (6.4 MHz vs. 5 MHz), and reduced supply current (550 µA vs. 1.3 mA). The substitute provides lower output current per channel (80 mA vs. 125 mA) and operates at maximum 6V supply versus 6.5V for the original part.

Secondary Substitute: TLV2460AQPWRG4Q1

The TLV2460AQPWRG4Q1 offers identical electrical specifications to the TLV2460QPWRG4Q1 with 617 units in stock and active product status. This part carries AEC-Q100 automotive qualification and provides the same extended temperature range and performance characteristics.

Not Recommended: TLV2460QPWG4

The TLV2460QPWG4 is discontinued at DiGi Electronics and should not be selected for new designs or long-term supply requirements, despite matching electrical specifications with other TLV2460 variants.

Frequently Asked Questions (FAQ)

Q: Can the TLV2460 series directly replace the MAX4166EUA+ on existing circuit boards?

A: Physical package compatibility requires verification. The MAX4166EUA+ uses 8-TSSOP/8-MSOP with 0.118" (3.00mm) width, while TLV2460 variants use 8-TSSOP with 0.173" (4.40mm) width. Pin configuration is compatible, but PCB footprint dimensions differ. Mechanical redesign of the landing pattern may be necessary.

Q: What are the key electrical differences between MAX4166EUA+ and TLV2460 substitutes?

A: The TLV2460 series provides superior input bias current performance (1.3 nA vs. 50 nA), higher bandwidth (6.4 MHz vs. 5 MHz), and lower quiescent current (550 µA vs. 1.3 mA). The MAX4166EUA+ offers higher output current capability (125 mA vs. 80 mA) and slightly higher slew rate (2 V/µs vs. 1.6 V/µs). Maximum supply voltage differs: MAX4166EUA+ supports 6.5V while TLV2460 variants support 6V maximum.

Q: Are the substitute parts suitable for automotive applications?

A: TLV2460AQPWRG4Q1 and TLV2460QPWRG4Q1 carry AEC-Q100 automotive qualification. The MAX4166EUA+ does not specify automotive qualification. If automotive-grade components are required, TLV2460AQPWRG4Q1 or TLV2460QPWRG4Q1 are appropriate selections.

Q: What is the temperature operating range difference?

A: The MAX4166EUA+ operates from -40°C to 85°C. All TLV2460 substitutes operate from -40°C to 125°C, providing 40°C additional high-temperature coverage. This extended range may be advantageous in thermal-constrained applications.

Q: Which substitute part should be selected for new designs?

A: TLV2460QPWRG4Q1 is the recommended choice for new designs. It maintains active product status with highest inventory availability (1036 units), carries AEC-Q100 qualification, and provides extended operating temperature range. Verify PCB footprint compatibility before implementation.

Q: Is the TLV2460QPWG4 available for procurement?

A: No. The TLV2460QPWG4 is discontinued at DiGi Electronics and should not be specified for new projects or long-term supply chains. Select TLV2460AQPWRG4Q1 or TLV2460QPWRG4Q1 instead.

Q: Do all parts meet RoHS and MSL requirements?

A: Yes. The MAX4166EUA+ and all TLV2460 substitutes are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting standard industrial compliance requirements.
