MAX427ESA+ Equivalent & Substitute Parts

Part Overview

The MAX427ESA+ is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface mount package. This device features a single differential output circuit with a gain bandwidth product of 8 MHz and a slew rate of 17 V/µs. The MAX427ESA+ is classified as obsolete, necessitating identification of active substitute components for new designs and ongoing production requirements. Equivalent parts must maintain compatibility with the 8-SOIC package format and support the specified electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX427ESA+ is determined by the following critical parameters: package format (8-SOIC), mounting type (surface mount), number of circuits (1), amplifier classification (general purpose), operating temperature range (-40°C ~ 85°C), and compliance certifications (ROHS3, MSL 1). The substitute parts identified maintain the same physical package dimensions and surface mount compatibility. All substitute components are manufactured by Analog Devices Inc., ensuring consistency in design heritage and performance characteristics. The substitutes are classified as active products, providing long-term availability and supply chain stability compared to the obsolete MAX427ESA+.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are manufactured by Analog Devices Inc. and maintain ROHS3 compliance and MSL 1 ratings consistent with the MAX427ESA+. The substitute components are classified as active products, ensuring continued availability and manufacturing support.

LT1007IS8 is an active general-purpose amplifier with matching 8 MHz gain bandwidth product and -40°C ~ 85°C operating temperature range. This device is suitable for applications where the supply voltage range of 8 V to 36 V is acceptable.

OP07CS8#PBF is an active general-purpose amplifier in 8-SOIC packaging. This device operates within a 0°C ~ 70°C temperature range, which is narrower than the MAX427ESA+ specification. Selection of this part requires confirmation that the application temperature requirements do not exceed 70°C.

OP27GSZ, OP27GSZ-REEL, and OP27GSZ-REEL7 are functionally equivalent active devices with identical electrical specifications. These parts differ only in packaging format: OP27GSZ is supplied in tube packaging, while OP27GSZ-REEL and OP27GSZ-REEL7 are supplied in cut tape and Digi-Reel® formats. All three variants maintain the -40°C ~ 85°C operating temperature range and 8 MHz gain bandwidth product. Selection between these variants depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the LT1007IS8 directly replace the MAX427ESA+ in all applications?

A: The LT1007IS8 maintains the same 8-SOIC package format, surface mount compatibility, and -40°C ~ 85°C operating temperature range. However, the supply voltage range differs: LT1007IS8 operates from 8 V to 36 V, while MAX427ESA+ operates at 44 V. Substitution is valid only for applications where the supply voltage requirement does not exceed 36 V.

Q: What is the difference between OP27GSZ, OP27GSZ-REEL, and OP27GSZ-REEL7?

A: These three part numbers represent the same operational amplifier with identical electrical specifications. The differences are in packaging and delivery format: OP27GSZ is supplied in tube packaging, OP27GSZ-REEL is supplied in cut tape with standard reel, and OP27GSZ-REEL7 is supplied in cut tape with Digi-Reel® format. Selection depends on assembly line requirements and inventory management preferences.

Q: Is the OP07CS8#PBF suitable for all MAX427ESA+ applications?

A: The OP07CS8#PBF is housed in the same 8-SOIC package and is ROHS3 compliant. However, the operating temperature range is limited to 0°C ~ 70°C, compared to the MAX427ESA+ range of -40°C ~ 85°C. This part is suitable only for applications that do not require operation below 0°C or above 70°C.

Q: What are the key electrical differences between the substitute parts?

A: The primary electrical differences are slew rate and input offset voltage. The MAX427ESA+ has a slew rate of 17 V/µs and input offset voltage of 5 µV. The LT1007IS8 and OP27 variants have lower slew rates (2.5 V/µs and 2.8 V/µs respectively) and higher input offset voltages (20 µV and 30 µV respectively). The OP07CS8#PBF has the lowest slew rate (0.25 V/µs) and highest input offset voltage (60 µV). Selection should be based on application requirements for transient response and DC accuracy.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all identified substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the MAX427ESA+.

Q: What is the inventory status of the substitute parts?

A: LT1007IS8 has 1,413 pieces in stock. OP07CS8#PBF has 1,001 pieces in stock. OP27GSZ has 55,200 pieces in stock. OP27GSZ-REEL has 44,113 pieces in stock. OP27GSZ-REEL7 has 50,100 pieces in stock. The OP27 variants offer significantly higher inventory availability.
