MAX407ESA Equivalent & Substitute Parts

Part Overview

The MAX407ESA is a general-purpose dual operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC surface-mount package. This device features rail-to-rail output capability and is designed for low-power applications requiring dual amplifier circuits. The MAX407ESA is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across key electrical parameters including supply voltage range, output type, circuit count, and package form factor.

Substitute Part Grouping Explanation

Substitute parts for the MAX407ESA are grouped into two functional categories based on electrical parameter compatibility:

Category 1: Direct Electrical Equivalents (Micropower Rail-to-Rail Amplifiers)

These substitutes maintain the low-power supply current characteristic (1–2 µA per channel) and low slew rate (0.004–0.005 V/µs) of the original MAX407ESA. Parts in this category include MAX407ESA+, LMC6442AIM/NOPB, LMC6442AIMX/NOPB, LMC6442IM/NOPB, and LMC6442IMX/NOPB. All operate within the 2.5–11 V supply range and maintain dual-circuit, rail-to-rail output configuration. These parts are suitable for applications where power consumption and bandwidth requirements match the original specification.

Category 2: Higher-Performance Alternatives (General-Purpose Rail-to-Rail Amplifiers)

These substitutes provide enhanced performance characteristics including higher slew rate (4 V/µs), higher gain-bandwidth product (12 MHz), and higher output current capability (100 mA per channel). Parts in this category include TLV2242ID, TLV2242IDR, TS462CDT, TS972IDT, and TS972IST. These parts operate within compatible supply voltage ranges (2.5–12 V or 2.7–10 V) and maintain dual-circuit, rail-to-rail output configuration. These parts are suitable for applications requiring faster signal processing or higher output drive capability than the original MAX407ESA.

Key Parameters Determining Substitution:

Dual-circuit configuration (2 amplifiers per package)
Rail-to-rail output capability
8-SOIC or compatible surface-mount package
Supply voltage range overlap with 2.5–10 V minimum requirement
Operating temperature range compatibility (-40°C minimum)

Engineering Selection Recommendations

For Direct Replacement (Micropower Applications):

Select MAX407ESA+ as the primary direct substitute. This part maintains identical electrical specifications to the MAX407ESA while offering active product status and ROHS3 compliance. The MAX407ESA+ is available in Tube packaging with 706 units in stock. When MAX407ESA+ availability is limited, the LMC6442 series (LMC6442AIM/NOPB, LMC6442AIMX/NOPB, LMC6442IM/NOPB, LMC6442IMX/NOPB) provides equivalent micropower performance with slightly higher gain-bandwidth product (10.5 kHz vs. 8 kHz) and lower input bias current (0.005 pA vs. 0.1 pA). All LMC6442 variants are ROHS3 compliant and active. LMC6442AIMX/NOPB offers the highest inventory (3210 units) in Tape & Reel packaging.

For Enhanced Performance Applications:

Select TS972IDT or TS972IST when higher slew rate (4 V/µs), higher gain-bandwidth product (12 MHz), and higher output current (100 mA per channel) are required. TS972IDT is available in 8-SOIC package with 15,604 units in stock and includes automotive qualification (AEC-Q100). TS972IST provides the same electrical performance in 8-TSSOP/8-MSOP package with 25,300 units in stock. Both parts are ROHS3 compliant and active.

For Cost-Optimized Selection:

TLV2242ID and TLV2242IDR offer lower input bias current (100 pA) and lower input offset voltage (0.6 mV) compared to MAX407ESA, with extended operating temperature range (-40°C to 125°C). TLV2242IDR in Cut Tape packaging provides 3,130 units in stock. Both are ROHS3 compliant and active.

Compliance Considerations:

All recommended substitutes are ROHS3 compliant and active products. The MAX407ESA is RoHS non-compliant; therefore, MAX407ESA+ or alternative substitutes must be selected for new designs subject to RoHS requirements. All parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q1: Can MAX407ESA+ be used as a direct drop-in replacement for MAX407ESA?

A: Yes. MAX407ESA+ maintains identical electrical specifications including slew rate (0.005 V/µs), gain-bandwidth product (8 kHz), supply voltage range (2.5–10 V), and dual rail-to-rail output configuration. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. Non-compliant). Both use 8-SOIC packaging with identical pinout.

Q2: What is the key difference between LMC6442 variants and MAX407ESA?

A: LMC6442 variants (AIM, AIMX, IM, IMX) provide superior input bias current (0.005 pA vs. 0.1 pA) and slightly higher gain-bandwidth product (10.5 kHz vs. 8 kHz). Supply voltage range is expanded to 1.8–11 V. All other parameters including slew rate, output type, and circuit count remain compatible. Packaging and pinout are identical (8-SOIC).

Q3: When should TS972IDT or TS972IST be selected instead of micropower alternatives?

A: Select TS972 variants when the application requires higher slew rate (4 V/µs vs. 0.005 V/µs), higher gain-bandwidth product (12 MHz vs. 8 kHz), or higher output current capability (100 mA vs. 600 µA per channel). These parts are suitable for signal conditioning, audio amplification, and instrumentation applications requiring faster response. TS972IDT maintains 8-SOIC packaging; TS972IST uses 8-TSSOP/8-MSOP packaging.

Q4: Are there packaging differences between substitute parts?

A: Most substitutes use 8-SOIC packaging identical to MAX407ESA. Exception: TS972IST uses 8-TSSOP/8-MSOP (MiniSO) packaging, which has different footprint dimensions (0.118" vs. 0.154" width). Verify PCB layout compatibility before selecting TS972IST. All other substitutes maintain 8-SOIC (0.154", 3.90mm width) compatibility.

Q5: What is the operating temperature range difference between substitutes?

A: MAX407ESA and most direct equivalents operate -40°C to 85°C. TLV2242 series and TS972 variants extend to -40°C to 125°C, providing wider temperature range for industrial and automotive applications. TS462CDT operates -20°C to 70°C, which is narrower than MAX407ESA and not recommended for extended temperature range requirements.

Q6: Which substitute offers the best inventory availability?

A: LMC6442IMX/NOPB provides the highest inventory with 8,003 units in stock (Tape & Reel packaging). TS972IST offers 25,300 units in stock (8-TSSOP/8-MSOP packaging). For 8-SOIC packaging specifically, LMC6442AIMX/NOPB provides 3,210 units. Verify current inventory status with supplier before final selection.

Q7: Are all substitutes RoHS compliant?

A: All recommended substitutes are ROHS3 compliant. MAX407ESA is RoHS non-compliant. For applications subject to RoHS requirements, select MAX407ESA+ or any LMC6442, TLV2242, or TS972 variant. All parts maintain REACH Unaffected status.

Q8: Can TLV2242 series be used in place of MAX407ESA?

A: TLV2242ID and TLV2242IDR are functionally compatible with lower slew rate (0.002 V/µs vs. 0.005 V/µs) and lower gain-bandwidth product (5.5 kHz vs. 8 kHz). These parts are suitable for low-frequency applications where bandwidth is not critical. Supply voltage range (2.5–12 V) and dual rail-to-rail output remain compatible. Extended operating temperature (-40°C to 125°C) provides advantage for wide-temperature applications.
