TLC2272ACDR Equivalent & Substitute Parts

Part Overview

The TLC2272ACDR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for general-purpose analog signal processing applications requiring low input bias current and moderate bandwidth performance. The part is currently in Active product status with 25,400 units in stock.

Substitute parts are necessary when the TLC2272ACDR becomes unavailable, when alternative performance characteristics better suit specific application requirements, or when design flexibility demands component options within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC2272ACDR is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: CMOS
• Number of Circuits: 2
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Output Type: Rail-to-Rail (primary requirement)

Allowable Parameter Variations: Substitute parts may differ in the following electrical characteristics while maintaining functional compatibility:

• Slew Rate: Substitute parts may have lower slew rates (1.5 V/µs acceptable)
• Gain Bandwidth Product: Substitute parts may have lower bandwidth (1.3 MHz acceptable)
• Current - Input Bias: Substitute parts may have lower input bias current (0.01 pA acceptable)
• Voltage - Input Offset: Substitute parts may have lower offset voltage (150 µV acceptable)
• Current - Supply: Substitute parts may have lower supply current (1.1 mA acceptable)
• Current - Output / Channel: Substitute parts may have lower output current (34 mA acceptable)
• Voltage - Supply Span: Substitute parts may have different supply voltage ranges (4.5 V to 15.5 V acceptable)
• Operating Temperature: Substitute parts may have extended temperature ranges (-40°C to 85°C acceptable)

All four substitute parts (LMC6082AIM/NOPB, LMC6082AIMX/NOPB, LMC6082IM/NOPB, LMC6082IMX/NOPB) meet these criteria and are classified as equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TLC2272ACDR The TLC2272ACDR remains the preferred choice for new designs. It is in Active product status with the highest inventory availability (25,400 units). The part is supplied in Cut Tape (CT) & Digi-Reel® packaging, suitable for automated assembly processes. Full RoHS3 compliance and MSL Level 1 rating ensure compatibility with modern manufacturing standards.

Secondary Selection: LMC6082AIMX/NOPB This substitute is recommended when TLC2272ACDR availability is constrained. It maintains Active product status with 2,700 units in stock and is supplied in Cut Tape (CT) & Digi-Reel® packaging. Electrical performance is reduced (lower slew rate and bandwidth), but all critical parameters remain within acceptable substitution limits. RoHS3 compliance and MSL Level 1 rating are maintained.

Tertiary Selection: LMC6082IMX/NOPB This part is suitable as a secondary alternative with 2,165 units available. It shares identical electrical specifications with LMC6082AIMX/NOPB and is supplied in Cut Tape (CT) & Digi-Reel® packaging. Active product status ensures continued availability.

Not Recommended for New Designs:

• LMC6082AIM/NOPB: Obsolete product status
• LMC6082IM/NOPB: Last Time Buy status indicates end-of-life phase

All substitute parts are manufactured by Texas Instruments, ensuring consistent quality and reliability standards. All parts comply with RoHS3 and REACH regulations with identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Frequently Asked Questions (FAQ)

Q: Can LMC6082 series parts directly replace TLC2272ACDR in existing designs?

A: Yes, LMC6082 series parts are direct pin-compatible substitutes in the 8-SOIC package. However, the reduced slew rate (1.5 V/µs versus 3.6 V/µs) and lower gain bandwidth product (1.3 MHz versus 2.25 MHz) must be evaluated against application timing requirements. Applications with stringent high-frequency performance demands may require circuit redesign or performance verification.

Q: What is the difference between LMC6082AIMX/NOPB and LMC6082IMX/NOPB?

A: Both parts have identical electrical specifications and packaging (Cut Tape & Digi-Reel®). The primary difference is the temperature grade designation: the "A" suffix in LMC6082AIMX/NOPB indicates a specific temperature classification variant. Both operate across -40°C to 85°C. Selection between these parts should be based on inventory availability and supplier lead times.

Q: Why do substitute parts have lower output current (34 mA versus 50 mA)?

A: The LMC6082 series is designed with different output stage architecture optimized for lower power consumption (1.1 mA supply current versus 2.4 mA). Applications requiring the full 50 mA output current capability of the TLC2272ACDR cannot use LMC6082 substitutes without external buffering stages.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all four substitute parts (LMC6082AIM/NOPB, LMC6082AIMX/NOPB, LMC6082IM/NOPB, LMC6082IMX/NOPB) are RoHS3 compliant with MSL Level 1 rating. They are suitable for use in applications subject to RoHS and REACH regulations.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tube packaging?

A: Cut Tape (CT) & Digi-Reel® packaging is optimized for automated pick-and-place assembly equipment and high-volume production. Tube packaging is suitable for manual assembly or lower-volume applications. For automated manufacturing, select parts supplied in Cut Tape (CT) & Digi-Reel® packaging: TLC2272ACDR, LMC6082AIMX/NOPB, or LMC6082IMX/NOPB.

Q: Can I use LMC6082AIM/NOPB or LMC6082IM/NOPB in new production designs?

A: LMC6082AIM/NOPB is Obsolete and LMC6082IM/NOPB is Last Time Buy. These parts are not recommended for new designs due to end-of-life status. Use LMC6082AIMX/NOPB or LMC6082IMX/NOPB for new production to ensure long-term supply continuity.

Q: What is the supply voltage range compatibility?

A: TLC2272ACDR operates from 4.4 V to 16 V. LMC6082 series parts operate from 4.5 V to 15.5 V. For applications using supply voltages below 4.5 V or above 15.5 V, the TLC2272ACDR is the only compatible option among these parts.
