MAX4415ESA+ Equivalent & Substitute Parts

Part Overview

The MAX4415ESA+ is a voltage feedback operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for rail-to-rail signal processing applications. This device integrates a single amplifier circuit in an 8-SOIC surface mount package and operates across a 2.7V to 5.5V supply range with an operating temperature span of -40°C to 85°C.

The MAX4415ESA+ is classified as an obsolete product. Locating equivalent substitute components becomes necessary when inventory depletion occurs or when design continuity requires sourcing from active product lines. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter tolerances to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4415ESA+ is determined by strict alignment across the following critical parameters:

Mechanical Compatibility: Package type must be 8-SOIC with identical pinout and footprint dimensions (0.154" width, 3.90mm). Mounting type must be Surface Mount to ensure PCB assembly compatibility without design modification.

Electrical Functional Class: Amplifier type must be Voltage Feedback with single circuit configuration and rail-to-rail output capability. These characteristics define the operational topology and signal processing behavior.

Supply Voltage Range: Substitute parts must operate within the specified 2.7V to 5.5V supply span. Parts with extended maximum supply voltage (such as 15V) remain compatible provided the minimum supply voltage does not exceed 2.7V.

Operating Temperature Range: Substitute parts must support the -40°C to 85°C operating temperature specification as a minimum requirement.

Regulatory Compliance: Parts must maintain ROHS3 compliance and MSL rating of 1 (Unlimited) to satisfy environmental and manufacturing process requirements.

The THS4221D from Texas Instruments meets all mechanical and functional substitution criteria while maintaining active product status and enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: THS4221D

The THS4221D from Texas Instruments qualifies as a direct functional substitute for the MAX4415ESA+ based on strict parameter alignment. Both devices share identical mechanical packaging (8-SOIC), matching supply voltage minimum (2.7V), identical operating temperature range (-40°C to 85°C), and equivalent regulatory compliance (ROHS3, MSL 1).

The THS4221D maintains active product status, ensuring long-term availability and supply chain continuity. This status distinction is significant given the MAX4415ESA+ obsolete classification.

Both parts satisfy the core substitution criteria: voltage feedback amplifier topology, single circuit configuration, rail-to-rail output capability, and surface mount assembly compatibility.

The THS4221D operates within an extended maximum supply voltage range (15V versus 5.5V), which does not compromise compatibility in applications designed for the MAX4415ESA+ 5.5V maximum specification. The extended range provides design flexibility for future applications without requiring component re-qualification.

Compliance certifications (ROHS3, EAR99 ECCN classification, HTSUS code 8542.33.0001) are equivalent across both parts, satisfying regulatory and export requirements.

Frequently Asked Questions (FAQ)

Q: Can the THS4221D directly replace the MAX4415ESA+ without PCB modification?

A: Yes. Both devices use identical 8-SOIC packaging with matching pinout and footprint dimensions (0.154" width, 3.90mm). No PCB layout changes are required for mechanical or electrical compatibility.

Q: What are the key differences between MAX4415ESA+ and THS4221D?

A: The THS4221D exhibits higher slew rate (990V/µs versus 470V/µs), greater -3dB bandwidth (230MHz versus 150MHz), lower input bias current (900nA versus 1.3µA), and higher output current capability (100mA versus 75mA). The THS4221D also operates at higher supply current (14mA versus 1.6mA) and supports extended maximum supply voltage (15V versus 5.5V). The MAX4415ESA+ provides lower input offset voltage (500µV versus 3mV).

Q: Is the THS4221D suitable for low-power applications designed for MAX4415ESA+?

A: The THS4221D draws higher supply current (14mA versus 1.6mA). Applications with strict power consumption constraints should evaluate this difference. However, both devices remain compatible from a functional and mechanical standpoint.

Q: Are there any supply voltage considerations when substituting?

A: Both parts operate at the same minimum supply voltage (2.7V). The THS4221D supports higher maximum voltage (15V). Circuits designed for MAX4415ESA+ at 5.5V maximum will operate within the THS4221D specification range without modification.

Q: What is the significance of the MAX4415ESA+ obsolete status?

A: Obsolete status indicates the manufacturer has discontinued production. The THS4221D active status ensures continued availability, manufacturing support, and supply chain reliability for long-term production requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both MAX4415ESA+ and THS4221D are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry EAR99 ECCN classification and HTSUS code 8542.33.0001, satisfying equivalent environmental and export requirements.

Q: Can the THS4221D be used in existing designs without circuit re-qualification?

A: Mechanical and electrical compatibility is established through parameter alignment. However, the performance differences (slew rate, bandwidth, input offset voltage, supply current) may affect circuit behavior in applications with tight performance specifications. Circuit-level validation is recommended for critical applications.
