MAX4252EUA Equivalent & Substitute Parts

Part Overview

The MAX4252EUA is a general-purpose operational amplifier featuring dual circuits with push-pull, rail-to-rail output configuration in an 8-uMAX/uSOP surface mount package. Manufactured by Analog Devices Inc./Maxim Integrated, this device operates across a 2.4V to 5.5V supply range with a 3 MHz gain-bandwidth product and 0.3V/µs slew rate.

The MAX4252EUA is classified as obsolete. Locating equivalent or substitute components is necessary for new designs, production continuity, and long-term system support. This reference provides direct substitutes based on electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4252EUA is determined by the following critical parameters:

Primary Compatibility Criteria:

• Dual-channel (2 circuits) operational amplifier architecture
• Rail-to-rail output capability
• Surface mount package with 8-pin configuration and 3.00mm width
• Supply voltage range compatibility: minimum 2.4V, maximum 5.5V
• Operating temperature range: -40°C to 85°C minimum

Secondary Performance Criteria:

• Slew rate, gain-bandwidth product, input bias current, input offset voltage, and output current drive capability

Two substitute parts meet the primary compatibility criteria:

1. MAX4252EUA+ — Direct manufacturer variant with identical electrical specifications and package footprint. Differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard).

2. OPA2340EA/2K5 — Texas Instruments CMOS alternative with compatible pinout, package footprint, and supply voltage range. Offers enhanced performance in slew rate (6V/µs vs. 0.3V/µs) and gain-bandwidth product (5.5 MHz vs. 3 MHz), with extended operating temperature range (-40°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

MAX4252EUA+ Selection Criteria:

The MAX4252EUA+ is the direct manufacturer equivalent with identical electrical performance and package footprint. This part is recommended when:

• Exact electrical parameter matching is required
• Design validation has been completed on the original MAX4252EUA specification
• Active product status and ROHS3 compliance are required
• Unlimited moisture sensitivity tolerance is acceptable

OPA2340EA/2K5 Selection Criteria:

The OPA2340EA/2K5 is a cross-manufacturer substitute recommended when:

• Enhanced slew rate (6V/µs) and gain-bandwidth product (5.5 MHz) provide performance advantages
• Extended operating temperature range (-40°C to 125°C) is required
• ROHS3 compliance is mandatory
• Higher supply current (750µA vs. 420µA) is acceptable within power budget constraints
• Lower output current per channel (50mA vs. 68mA) meets application requirements
• Slightly higher input offset voltage (150µV vs. 70µV) is tolerable
• Moisture sensitivity level 2 (1-year shelf life) is compatible with storage and handling procedures

Both substitutes maintain identical pinout and 8-pin surface mount package configuration, enabling direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX4252EUA+ be used as a direct replacement for MAX4252EUA?

A: Yes. The MAX4252EUA+ shares identical electrical specifications, pinout, and package footprint. The primary differences are product status (Active vs. Obsolete) and packaging format (Tube). No circuit modifications are required.

Q: What are the key differences between MAX4252EUA and OPA2340EA/2K5?

A: Both devices are dual-channel, rail-to-rail operational amplifiers in compatible 8-pin surface mount packages. The OPA2340EA/2K5 offers superior slew rate (6V/µs vs. 0.3V/µs) and higher gain-bandwidth product (5.5 MHz vs. 3 MHz). However, it draws higher supply current (750µA vs. 420µA), provides lower output current per channel (50mA vs. 68mA), and has higher input offset voltage (150µV vs. 70µV). Operating temperature range extends to 125°C on the OPA2340EA/2K5.

Q: Are there PCB layout considerations when substituting these parts?

A: All three parts (MAX4252EUA, MAX4252EUA+, OPA2340EA/2K5) use identical 8-pin TSSOP/MSOP packages with 3.00mm width and 0.118" pitch. PCB footprints are directly compatible. No layout modifications are necessary.

Q: What is the minimum supply voltage for each part?

A: MAX4252EUA and MAX4252EUA+ require minimum 2.4V. OPA2340EA/2K5 requires minimum 2.5V. Designs operating below 2.5V must use MAX4252EUA or MAX4252EUA+.

Q: Which substitute is recommended for new designs?

A: For new designs requiring exact performance matching, use MAX4252EUA+. For applications benefiting from higher speed performance and extended temperature range, use OPA2340EA/2K5. Both are active products with ROHS3 compliance.

Q: How does moisture sensitivity affect component handling?

A: MAX4252EUA and MAX4252EUA+ have MSL 1 (Unlimited shelf life). OPA2340EA/2K5 has MSL 2 (1-year shelf life from manufacturing date). MSL 2 components require controlled storage conditions and have a defined reflow window after bag opening.

Q: Can OPA2340EA/2K5 be used in applications requiring 68mA output current per channel?

A: No. OPA2340EA/2K5 provides maximum 50mA per channel. Applications requiring 68mA output current must use MAX4252EUA or MAX4252EUA+.
