LMC6572BIM Equivalent & Substitute Parts

Part Overview

The LMC6572BIM 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, indicating it has been discontinued by the manufacturer. Due to its obsolete status and non-RoHS3 compliance, identifying functionally equivalent substitute components is essential for ongoing design support, production continuity, and compliance with current environmental regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6572BIM is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of circuits: 2 (dual amplifier configuration)
• Package type: 8-SOIC surface mount
• Output configuration: Rail-to-rail capability
• Supply voltage range compatibility: Minimum 2.7 V to maximum 11 V overlap
• Operating temperature range: Minimum -40°C to maximum 85°C coverage

Substitution Logic: Equivalent parts must maintain the same circuit count, identical package footprint, and compatible supply voltage specifications to ensure direct replacement without PCB redesign. Rail-to-rail output is a functional requirement for this application class. Substitute parts are grouped based on whether they meet all mechanical and electrical constraints simultaneously.

Parameter Comparison

Engineering Selection Recommendations

MAX407CSA+T and MAX407CSA+ (Analog Devices Inc./Maxim Integrated): These parts are active, ROHS3-compliant alternatives with identical dual-circuit, 8-SOIC configuration. Both maintain rail-to-rail output and compatible supply voltage ranges (2.5 V to 10 V). The operating temperature range is narrower (0°C to 70°C) compared to the LMC6572BIM. These devices are suitable for applications where the reduced temperature range and lower slew rate (0.005 V/µs versus 0.09 V/µs) are acceptable. The significantly lower supply current (1 µA versus 160 µA) provides power efficiency benefits.

ALD2706BSAL (Advanced Linear Devices Inc.): This CMOS amplifier maintains the dual-circuit, 8-SOIC package configuration with rail-to-rail output and ROHS3 compliance. The supply voltage range (2 V to 10 V) provides broader minimum voltage coverage. The slew rate (0.1 V/µs) and gain bandwidth product (200 kHz) are closer to the original LMC6572BIM specifications. However, the operating temperature range (0°C to 70°C) is narrower, and output current per channel (0.2 mA) is significantly reduced compared to the original device (6 mA).

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected, addressing environmental and regulatory requirements that the obsolete LMC6572BIM does not meet. Selection should prioritize active product status and compliance certification for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can MAX407CSA+T and MAX407CSA+ be used interchangeably with LMC6572BIM? A: Both parts share identical electrical specifications and package configuration. Direct substitution is mechanically and electrically feasible. However, verify that the narrower operating temperature range (0°C to 70°C versus -40°C to 85°C) and lower slew rate (0.005 V/µs versus 0.09 V/µs) are acceptable for your application requirements.

Q: What are the key differences between MAX407CSA+T and MAX407CSA+? A: Both parts are functionally identical with the same electrical specifications and 8-SOIC package. The primary difference is packaging format: MAX407CSA+T is supplied in tape format, while MAX407CSA+ is supplied in tube format. Selection depends on assembly process requirements.

Q: Is ALD2706BSAL a suitable replacement for LMC6572BIM? A: ALD2706BSAL maintains the dual-circuit, 8-SOIC configuration and rail-to-rail output. However, the output current per channel (0.2 mA) is substantially lower than the original device (6 mA). This substitute is suitable only if your application does not require the higher output current specification of the LMC6572BIM.

Q: Why is the operating temperature range narrower in substitute parts? A: The substitute parts (MAX407 and ALD2706) are specified for 0°C to 70°C operation, while the LMC6572BIM operates from -40°C to 85°C. Applications requiring extended temperature range operation must verify that substitute parts meet the full temperature requirements of the end application.

Q: Are all substitute parts RoHS3 compliant? A: Yes. MAX407CSA+T, MAX407CSA+, and ALD2706BSAL are all ROHS3 compliant, addressing environmental regulations that the obsolete LMC6572BIM does not meet.

Q: What is the difference between push-pull and rail-to-rail output? A: The LMC6572BIM specifies push-pull, rail-to-rail output. All substitute parts specify rail-to-rail output only. Rail-to-rail output indicates the amplifier can swing its output voltage to within a small margin of both supply rails. Push-pull topology refers to the output stage configuration. Substitute parts with rail-to-rail output are functionally compatible for applications requiring output voltage swing to supply rail limits.

Q: Can I use these substitutes in existing PCB designs without modification? A: Yes. All substitute parts use the identical 8-SOIC (0.154", 3.90mm Width) package footprint, enabling direct PCB placement without redesign. Verify that electrical parameter differences (slew rate, gain bandwidth product, output current, supply current) do not conflict with circuit design requirements.
