MAX407ESA+ Equivalent & Substitute Parts Reference

Part Overview

The MAX407ESA+ is a general-purpose dual operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, designed for rail-to-rail applications in low-power signal conditioning and amplification circuits. This 8-SOIC surface-mount device operates across a 2.5V to 10V supply range with an operating temperature range of -40°C to 85°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching functional category (general-purpose dual operational amplifier), identical package type (8-SOIC), rail-to-rail output capability, and compatible electrical operating parameters. Substitutes are selected where supply constraints, packaging preferences, or specific performance characteristics require alternative sourcing while maintaining circuit functionality.

Substitute Part Grouping Explanation

Substitute parts for the MAX407ESA+ are grouped into two functional categories based on electrical performance characteristics:

Category 1: Micropower Rail-to-Rail Amplifiers (LMC6442 Series) These substitutes maintain the micropower supply current specification (1.9µA per channel) and low input bias current (0.005 pA), making them suitable for battery-powered and ultra-low-power applications. Parts include LMC6442AIM/NOPB, LMC6442AIMX/NOPB, LMC6442IM/NOPB, and LMC6442IMX/NOPB. These devices operate across an extended supply range (1.8V to 11V) and are available in multiple packaging formats (Tube, Tape & Reel, Bulk).

Category 2: General-Purpose Rail-to-Rail Amplifiers (TLV2242 and TS972 Series) These substitutes provide alternative performance profiles. The TLV2242ID and TLV2242IDR offer extended operating temperature range (-40°C to 125°C) with lower input offset voltage (600µV) but reduced output current capability (200µA). The TS972IDT and TS972IST provide significantly higher slew rate (4V/µs) and gain bandwidth product (12MHz), suitable for higher-frequency applications, with automotive-grade qualification (AEC-Q100).

Substitution Criteria:

Package type: 8-SOIC (0.154", 3.90mm Width) or compatible 8-pin surface-mount variants
Output configuration: Rail-to-rail
Dual-channel configuration: 2 circuits per package
Supply voltage compatibility: Minimum 2.5V operation
Operating temperature overlap: -40°C minimum
Surface-mount technology: All candidates are surface-mount devices

Engineering Selection Recommendations

For Direct Replacement (Micropower Applications): The LMC6442 series (LMC6442AIM/NOPB, LMC6442AIMX/NOPB, LMC6442IM/NOPB, LMC6442IMX/NOPB) provides the closest functional equivalence to the MAX407ESA+. These devices maintain micropower supply current specifications and are available in standard 8-SOIC packaging. Selection between tube, tape & reel, and bulk packaging depends on production volume and assembly requirements. All LMC6442 variants carry ROHS3 compliance and MSL 1 rating, matching the original part's environmental specifications.

For Extended Temperature Range Applications: The TLV2242ID and TLV2242IDR extend the operating temperature range to -40°C to 125°C, providing additional thermal margin for industrial and automotive environments. These parts maintain 8-SOIC packaging and ROHS3 compliance. The trade-off is reduced output current capability (200µA versus 600µA on the MAX407ESA+) and lower gain bandwidth product (5.5kHz versus 8kHz).

For High-Speed Applications: The TS972IDT and TS972IST deliver significantly higher performance with 4V/µs slew rate and 12MHz gain bandwidth product, suitable for applications requiring faster signal processing. The TS972IDT maintains 8-SOIC packaging, while the TS972IST uses 8-TSSOP/8-MSOP (MiniSO) packaging. Both variants carry AEC-Q100 automotive qualification and extended temperature range (-40°C to 125°C). Supply current increases to 2mA per channel.

Packaging Considerations: All substitutes except TS972IST are available in standard 8-SOIC (0.154", 3.90mm Width) packaging, ensuring direct PCB footprint compatibility with the MAX407ESA+. The TS972IST uses 8-TSSOP/8-MSOP packaging, which requires PCB layout modification but offers reduced board space.

Compliance and Availability: All identified substitutes maintain ROHS3 compliance and MSL 1 moisture sensitivity rating. Inventory levels vary: LMC6442IMX/NOPB (8003 pcs), TS972IST (25300 pcs), and TS972IDT (15604 pcs) offer highest availability. Product status is active for all candidates.

Frequently Asked Questions (FAQ)

Q1: Can I use LMC6442 series parts as direct pin-for-pin replacements for MAX407ESA+?

A: Yes. The LMC6442 series (all variants) are pin-compatible with the MAX407ESA+ in 8-SOIC packaging. No PCB layout modifications are required. Electrical performance is comparable, with LMC6442 devices offering slightly lower slew rate (0.0041V/µs versus 0.005V/µs) and higher input offset voltage (1.5mV versus 1mV), but these differences are negligible in most general-purpose amplifier applications.

Q2: What is the difference between LMC6442AIM/NOPB (Tube) and LMC6442AIMX/NOPB (Tape & Reel)?

A: Both parts are electrically identical. The difference is packaging format: Tube packaging is used for lower-volume orders and manual assembly, while Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly. LMC6442AIMX/NOPB offers higher inventory availability (3210 pcs) compared to LMC6442AIM/NOPB (813 pcs).

Q3: Can I substitute TS972IDT for MAX407ESA+ in a low-power battery application?

A: TS972IDT is not recommended for ultra-low-power applications. The TS972IDT draws 2mA supply current per channel (versus 1µA for MAX407ESA+), resulting in 2000x higher power consumption. This makes it unsuitable for battery-powered designs. Use LMC6442 series instead for low-power requirements.

Q4: What are the key differences between TLV2242ID and MAX407ESA+?

A: TLV2242ID offers extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and lower input offset voltage (600µV versus 1mV). However, it has reduced output current capability (200µA versus 600µA) and lower gain bandwidth product (5.5kHz versus 8kHz). TLV2242ID is suitable for precision, temperature-sensitive applications where output current demands are moderate.

Q5: Is TS972IST compatible with MAX407ESA+ PCB layouts?

A: TS972IST uses 8-TSSOP/8-MSOP (MiniSO) packaging instead of 8-SOIC. While pin count and function are identical, the physical footprint differs. PCB layout modification is required. However, the smaller package size (0.118" versus 0.154" width) may provide board space advantages in compact designs.

Q6: Which substitute offers the best performance for high-frequency signal conditioning?

A: TS972IDT and TS972IST provide the highest performance with 4V/µs slew rate and 12MHz gain bandwidth product. These are suitable for applications requiring faster transient response and higher-frequency signal processing. Both variants carry AEC-Q100 automotive qualification and extended temperature range.

Q7: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes (LMC6442 series, TLV2242 series, TS972 series) carry ROHS3 compliance certification and MSL 1 moisture sensitivity rating, matching the environmental specifications of MAX407ESA+.

Q8: What is the supply voltage compatibility range across all substitutes?

A: The LMC6442 series offers the widest supply range (1.8V to 11V), exceeding the MAX407ESA+ specification (2.5V to 10V). TLV2242 series supports 2.5V to 12V. TS972 series operates at 2.7V to 10V. All substitutes are compatible with the MAX407ESA+ supply voltage window (2.5V to 10V).
