LMC6572AIM Equivalent & Substitute Parts

Part Overview

The LMC6572AIM is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in a push-pull, rail-to-rail output configuration housed in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of functionally equivalent substitute components essential for design continuity and procurement planning. The LMC6572AIM operates across a supply voltage range of 2.7 V to 11 V with an operating temperature range of -40°C to 85°C, serving applications requiring low-power, dual-channel amplification in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6572AIM is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual-circuit (2 channels) general-purpose operational amplifier configuration
• Rail-to-rail output capability
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply voltage range compatibility: minimum 2.7 V to 11 V operation
• Operating temperature range: -40°C to 85°C

Secondary Compatibility Parameters:

• Slew rate performance
• Gain bandwidth product
• Input bias current
• Input offset voltage
• Supply current per channel
• Output current per channel

The substitute parts identified—MAX4163ESA+, MAX417CSA+, and MAX417CSA+T—meet the primary substitution criteria of dual-channel, rail-to-rail operation in 8-SOIC packaging. However, each substitute exhibits distinct electrical characteristics that must be evaluated against specific application requirements.

Engineering Selection Recommendations

MAX4163ESA+ Selection Criteria: The MAX4163ESA+ is an active product from Analog Devices Inc./Maxim Integrated with ROHS3 compliance. This substitute maintains compatibility across the full operating temperature range (-40°C to 85°C) and provides improved input bias current performance (1 pA versus 10 pA). The maximum supply voltage is reduced to 10 V, which is acceptable for applications not requiring the full 11 V capability of the LMC6572AIM. Output current capability is increased to 15 mA per channel, supporting higher load requirements. Supply current consumption is significantly reduced to 25 µA across both channels, benefiting power-constrained applications.

MAX417CSA+ and MAX417CSA+T Selection Criteria: Both MAX417CSA+ and MAX417CSA+T variants are active products with ROHS3 compliance. These parts offer the lowest supply current consumption (1 µA across both channels) and superior input bias current performance (0.1 pA). However, the operating temperature range is restricted to 0°C to 70°C, making these substitutes unsuitable for applications requiring the full -40°C to 85°C range of the LMC6572AIM. Output current per channel is limited to 600 µA, restricting use in high-current output applications. The gain bandwidth product is reduced to 150 kHz compared to the original 220 kHz specification.

Compliance Consideration: All substitute parts achieve ROHS3 compliance, addressing regulatory requirements that the obsolete LMC6572AIM does not meet. Selection between substitutes depends on application-specific requirements for temperature range, output current, and power consumption rather than on general compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX417CSA+ directly replace LMC6572AIM in all applications?

A: No. While MAX417CSA+ shares the same 8-SOIC package and dual-channel, rail-to-rail configuration, its operating temperature range is limited to 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must use MAX4163ESA+ or retain the original LMC6572AIM. Additionally, output current per channel is reduced to 600 µA, which may be insufficient for high-current applications.

Q: What is the primary advantage of MAX4163ESA+ over MAX417CSA+?

A: MAX4163ESA+ maintains the full -40°C to 85°C operating temperature range of the LMC6572AIM and provides 15 mA output current per channel compared to 600 µA in MAX417CSA+. These characteristics make MAX4163ESA+ suitable for a broader range of temperature and load conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. MAX4163ESA+, MAX417CSA+, and MAX417CSA+T are all ROHS3 compliant. The original LMC6572AIM is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulations.

Q: What is the difference between MAX417CSA+ and MAX417CSA+T?

A: Both parts share identical electrical specifications and operating characteristics. The primary difference is packaging designation. MAX417CSA+ is supplied in tube packaging, while MAX417CSA+T uses tape-and-reel packaging. Electrical performance and pin configuration are equivalent.

Q: Can I use MAX417CSA+ in a -40°C application?

A: No. MAX417CSA+ is rated for 0°C to 70°C operation only. For applications requiring -40°C operation, use MAX4163ESA+, which maintains the full -40°C to 85°C temperature range.

Q: How does supply current consumption compare across substitutes?

A: LMC6572AIM: 160 µA (both channels); MAX4163ESA+: 25 µA (both channels); MAX417CSA+/MAX417CSA+T: 1 µA (both channels). MAX417 variants offer the lowest power consumption, while MAX4163ESA+ provides a middle ground between power efficiency and performance.

Q: Are the pin configurations identical across all parts?

A: All parts use the 8-SOIC package with 0.154" (3.90mm) width. Pin configuration compatibility is determined by the dual-channel, general-purpose operational amplifier topology. Verify pinout diagrams in manufacturer datasheets before PCB layout or rework.
