Number of circuits: 2 channels
Output type: Rail-to-rail capability
Supply voltage range: Minimum 4.4 V to maximum 16 V
Operating temperature range: -55°C to 125°C
Amplifier type: CMOS technology

Acceptable Substitutes:

The TLC2272AMDR represents the direct equivalent, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel). All electrical specifications remain identical.

The LMC6082 series (LMC6082AIMX/NOPB, LMC6082IMX/NOPB, LMC6082AIM/NOPB, LMC6082IM/NOPB) provides functional substitution with the following parameter differences: reduced slew rate (1.5 V/µs versus 3.6 V/µs), lower gain bandwidth product (1.3 MHz versus 2.25 MHz), lower input bias current (0.01 pA versus 1 pA), lower input offset voltage (150 µV versus 300 µV), reduced supply current (1.1 mA versus 2.4 mA per channel), and reduced output current per channel (34 mA versus 50 mA). The LMC6082 series operates within a narrower temperature range (-40°C to 85°C) and supply voltage range (4.5 V to 15.5 V).

Engineering Selection Recommendations

Primary Recommendation: TLC2272AMDR

The TLC2272AMDR is the preferred substitute for the discontinued TLC2272AMDRG4. This part maintains identical electrical specifications across all measured parameters and differs only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel). The TLC2272AMDR holds Active product status, ensuring long-term availability and supply chain stability. Both parts are ROHS3 compliant with MSL 1 rating, confirming equivalent environmental and handling requirements.

Secondary Recommendation: LMC6082AIMX/NOPB or LMC6082IMX/NOPB

The LMC6082 series provides functional substitution for applications where reduced performance specifications are acceptable. These parts maintain the 8-SOIC package format and dual-channel CMOS amplifier architecture. The LMC6082AIMX/NOPB and LMC6082IMX/NOPB both carry Active product status with Cut Tape & Digi-Reel packaging. Selection between these variants depends on temperature and supply voltage requirements within the narrower operating ranges specified for the LMC6082 series.

Substitution Constraints:

Applications requiring the full operating temperature range (-55°C to 125°C) or maximum supply voltage of 16 V must use TLC2272AMDR. Applications requiring slew rates exceeding 1.5 V/µs or output currents exceeding 34 mA per channel must use TLC2272AMDR. The LMC6082 series is suitable only for applications operating within -40°C to 85°C temperature range and 4.5 V to 15.5 V supply voltage range.

Frequently Asked Questions (FAQ)

Q: Can TLC2272AMDR be used as a direct replacement for TLC2272AMDRG4?

A: Yes. The TLC2272AMDR provides direct electrical equivalence with identical specifications for all measured parameters. The only difference is packaging format: TLC2272AMDRG4 is supplied in Cut Tape & Digi-Reel format, while TLC2272AMDR is supplied in Tape & Reel format. Both are 8-SOIC surface mount packages with identical pinout and footprint.

Q: What are the key differences between TLC2272AMDR and LMC6082 series substitutes?

A: The TLC2272AMDR maintains higher performance specifications: slew rate of 3.6 V/µs (versus 1.5 V/µs for LMC6082), gain bandwidth product of 2.25 MHz (versus 1.3 MHz), and output current of 50 mA per channel (versus 34 mA). The TLC2272AMDR also supports the full extended temperature range of -55°C to 125°C and supply voltage range of 4.4 V to 16 V, while LMC6082 is limited to -40°C to 85°C and 4.5 V to 15.5 V.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TLC2272AMDR, LMC6082AIMX/NOPB, LMC6082IMX/NOPB, LMC6082AIM/NOPB, LMC6082IM/NOPB) are ROHS3 compliant with MSL 1 rating, matching the compliance status of the original TLC2272AMDRG4.

Q: Which substitute should be selected for high-temperature applications?

A: Only TLC2272AMDR supports the extended operating temperature range of -55°C to 125°C. The LMC6082 series is limited to -40°C to 85°C and is unsuitable for applications requiring operation above 85°C or below -40°C.

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

A: Both parts are electrically identical with identical specifications. The difference lies in product status: LMC6082AIMX/NOPB is Active, while LMC6082IMX/NOPB is also Active. Both are supplied in Cut Tape & Digi-Reel packaging. Selection between these variants should be based on supplier availability and lead time.

Q: Can LMC6082 series parts be used in applications requiring 16 V supply voltage?

A: No. The LMC6082 series maximum supply voltage is 15.5 V. Applications requiring 16 V operation must use TLC2272AMDR, which supports supply voltages up to 16 V.

Q: Are the 8-SOIC packages for all substitute parts mechanically identical?

A: Yes. All substitute parts use the 8-SOIC package with dimensions of 0.154" width and 3.90 mm width. The pinout and footprint are identical across all listed parts, enabling direct PCB-level substitution without layout modifications.
