MAX4016ESA Equivalent & Substitute Parts

Part Overview

The MAX4016ESA is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This dual-channel operational amplifier features rail-to-rail output capability in an 8-SOIC surface mount package. The device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. Substitute parts must maintain functional compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4016ESA is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90 mm).

Amplifier Architecture: Voltage feedback topology is required for functional equivalence.

Circuit Count and Output Configuration: The MAX4016ESA contains 2 circuits with rail-to-rail output. Substitutes must support equivalent channel configuration and output swing characteristics.

Electrical Performance Envelope: Operating temperature range (-40°C to 85°C), supply voltage span (minimum 3.15 V, maximum 11 V), and output current capability (120 mA per channel) define the acceptable performance boundaries.

Compliance Status: Active product status and current RoHS3 compliance are preferred for new designs and ongoing production.

Two substitute parts are identified:

1. MAX4016ESA+ — Direct manufacturer equivalent with identical electrical specifications, active product status, and improved compliance profile.

2. THS4211D — Texas Instruments voltage feedback amplifier with enhanced performance characteristics, suitable for applications where increased bandwidth and slew rate are beneficial.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Specifications):

The MAX4016ESA+ is the primary substitute for the obsolete MAX4016ESA. Both parts share identical electrical specifications, including slew rate (600 V/µs), bandwidth (150 MHz), supply current (5.5 mA per channel), and output current capability (120 mA per channel). The MAX4016ESA+ maintains the dual-channel configuration with rail-to-rail output in the same 8-SOIC package. The critical advantage is active product status and RoHS3 compliance, eliminating supply chain risk and meeting current regulatory requirements. This part is suitable for direct substitution in existing designs without circuit modification.

For Performance-Enhanced Applications:

The THS4211D from Texas Instruments offers enhanced performance characteristics with increased slew rate (970 V/µs) and bandwidth (325 MHz). However, this part contains a single circuit rather than dual circuits, requiring circuit redesign if both channels are utilized. The THS4211D also specifies a minimum supply voltage of 5 V (versus 3.15 V for the MAX4016ESA), which may restrict operation in low-voltage applications. The higher supply current (19 mA) and output current capability (220 mA per channel) indicate increased power consumption. Selection of the THS4211D is appropriate only when the application requires enhanced bandwidth and slew rate performance, and when single-channel operation or dual-device implementation is acceptable.

Compliance Considerations:

Both substitute parts are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The MAX4016ESA+ is the recommended choice for production environments requiring compliance documentation and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MAX4016ESA+ be used as a direct replacement for the MAX4016ESA?

A: Yes. The MAX4016ESA+ is electrically and mechanically identical to the MAX4016ESA. Both parts feature identical slew rate, bandwidth, input bias current, input offset voltage, supply current, output current, and supply voltage specifications. The 8-SOIC package dimensions are identical. The primary difference is product status (active versus obsolete) and RoHS compliance. No circuit modification is required.

Q: What are the key differences between the MAX4016ESA and THS4211D?

A: The MAX4016ESA contains 2 circuits; the THS4211D contains 1 circuit. The THS4211D offers higher slew rate (970 V/µs versus 600 V/µs) and bandwidth (325 MHz versus 150 MHz). The THS4211D requires minimum 5 V supply (versus 3.15 V minimum for MAX4016ESA) and draws higher supply current (19 mA versus 5.5 mA per channel). The THS4211D provides higher output current capability (220 mA versus 120 mA per channel). These differences make the THS4211D unsuitable for direct replacement in low-voltage or dual-channel applications.

Q: Is the THS4211D suitable for applications requiring dual-channel operation?

A: No. The THS4211D is a single-channel device. Applications requiring dual-channel operation would require two THS4211D devices, increasing board space, cost, and power consumption. The MAX4016ESA+ remains the appropriate choice for dual-channel requirements.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC package is a surface mount integrated circuit package with 8 pins, 0.154 inches (3.90 mm) width. All three parts (MAX4016ESA, MAX4016ESA+, and THS4211D) use this identical package, ensuring mechanical compatibility with existing printed circuit board layouts and assembly processes.

Q: Why is the MAX4016ESA classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, technology advancement, and production decisions. The MAX4016ESA+ is the active replacement, offering identical functionality with current manufacturing and compliance standards.

Q: Are there supply voltage compatibility concerns when substituting parts?

A: The MAX4016ESA and MAX4016ESA+ operate across 3.15 V to 11 V supply range. The THS4211D operates across 5 V to 15 V range. Applications using supply voltages below 5 V cannot use the THS4211D. The MAX4016ESA+ maintains compatibility with the original supply voltage envelope.

Q: What is the impact of higher supply current in the THS4211D?

A: The THS4211D draws 19 mA total supply current compared to 5.5 mA per channel (11 mA total for dual channels) in the MAX4016ESA. This increased current consumption results in higher power dissipation, requiring consideration of thermal management, power supply capacity, and battery life in portable applications. The MAX4016ESA+ maintains the original low-power specification.
