TLC2272AMD Equivalent & Substitute Parts

Part Overview

The TLC2272AMD is a CMOS dual-channel operational amplifier manufactured by Texas Instruments in 8-SOIC surface mount packaging. 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 1066 units in stock. Substitute parts are necessary when the TLC2272AMD becomes unavailable, when alternative performance characteristics are required within compatible electrical and mechanical parameters, or when design flexibility demands component options from different manufacturers while maintaining functional equivalence in 8-SOIC packaging.

Substitute Part Grouping Explanation

Substitution eligibility for the TLC2272AMD is determined by strict alignment with the following electrical and mechanical criteria:

Mandatory Compatibility Parameters:

Dual-channel configuration (2 circuits)
8-SOIC surface mount package (0.154", 3.90mm width)
Rail-to-rail output capability
Supply voltage range compatibility (minimum 4.4V to 16V maximum)
Operating temperature range support (-55°C to 125°C or subset thereof)
ROHS3 compliance and MSL 1 rating

Electrical Performance Boundaries: Substitute parts must operate within the specified supply voltage span and support the dual-channel architecture. Output current capability, slew rate, gain bandwidth product, and input bias current are secondary selection criteria that may vary between substitutes while maintaining functional compatibility.

The substitute parts identified—LMC6082AIM/NOPB, LMC6082AIMX/NOPB, LMC6082IM/NOPB, LMC6082IMX/NOPB, and AD8642ARZ—all meet the mandatory mechanical and primary electrical requirements. These parts share identical 8-SOIC packaging, dual-channel topology, and rail-to-rail output configuration. Differences in amplifier technology (CMOS versus J-FET), slew rate, bandwidth, and supply current represent performance variations that must be evaluated against specific application requirements.

Engineering Selection Recommendations

Active Status Substitutes (Preferred for New Designs):

LMC6082AIMX/NOPB and LMC6082IMX/NOPB are both in Active product status and available in Cut Tape (CT) & Digi-Reel packaging. These Texas Instruments CMOS dual-channel amplifiers maintain full ROHS3 compliance and MSL 1 rating. Both parts are electrically identical with 1.5V/µs slew rate and 1.3MHz gain bandwidth product. The AIMX variant carries 4050 units in inventory; the IMX variant carries 2165 units. These parts are suitable for applications where the lower slew rate and bandwidth of the LMC6082 series are acceptable compared to the TLC2272AMD.

Alternative Technology Substitute (Active Status):

AD8642ARZ from Analog Devices Inc. is in Active product status with 5400 units in stock. This J-FET amplifier offers superior performance characteristics including 3.0V/µs slew rate, 3.5MHz gain bandwidth product, and significantly lower supply current (200µA per channel versus 2.4mA for TLC2272AMD). The AD8642ARZ supports an extended maximum supply voltage of 26V and maintains operating temperature range of -40°C to 125°C. This substitute is appropriate for applications requiring lower power consumption or higher bandwidth performance.

Transitional Status Substitutes (Limited Availability):

LMC6082AIM/NOPB is marked Obsolete but carries 4050 units in inventory. LMC6082IM/NOPB is marked Last Time Buy with 4276 units available. Both are CMOS dual-channel devices in Tube packaging. These parts should be considered only when inventory of Active-status alternatives is insufficient and design timelines permit component qualification.

Compliance and Regulatory Alignment:

All identified substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and EAR99 export classification. All parts are REACH Unaffected. These regulatory and compliance attributes are consistent across the TLC2272AMD and all substitute options.

Frequently Asked Questions (FAQ)

Q: Can LMC6082 series parts directly replace TLC2272AMD in existing designs?

A: LMC6082 series parts (LMC6082AIM/NOPB, LMC6082AIMX/NOPB, LMC6082IM/NOPB, LMC6082IMX/NOPB) share identical 8-SOIC packaging and dual-channel configuration. However, they exhibit lower slew rate (1.5V/µs versus 3.6V/µs) and lower gain bandwidth product (1.3MHz versus 2.25MHz). Direct substitution is mechanically compatible but requires verification that application performance requirements do not depend on the higher slew rate or bandwidth of the TLC2272AMD.

Q: What are the key differences between CMOS and J-FET amplifier types in this comparison?

A: The TLC2272AMD and LMC6082 series are CMOS technology. The AD8642ARZ is J-FET technology. J-FET amplifiers (AD8642ARZ) provide lower input bias current (0.25pA versus 1pA for TLC2272AMD) and significantly lower supply current per channel (200µA versus 2.4mA). CMOS amplifiers generally offer higher output current capability. Technology selection depends on application requirements for input impedance, power consumption, and output drive capability.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use 8-SOIC (0.154", 3.90mm width) surface mount packaging, identical to the TLC2272AMD. Packaging variants differ only in distribution format: Tube packaging versus Cut Tape (CT) & Digi-Reel. These distribution formats do not affect electrical or mechanical compatibility; they reflect supply chain and handling preferences.

Q: What is the significance of product status (Active, Obsolete, Last Time Buy)?

A: Active status indicates the manufacturer continues production and supports long-term availability. Obsolete status indicates the manufacturer has discontinued production; existing inventory may be available but no future supply is guaranteed. Last Time Buy status indicates the manufacturer has announced end-of-life; customers are advised to place final orders within a specified window. For new designs, Active-status parts (LMC6082AIMX/NOPB, LMC6082IMX/NOPB, AD8642ARZ) are preferred.

Q: How do supply voltage ranges affect substitution compatibility?

A: The TLC2272AMD operates from 4.4V to 16V. LMC6082 series parts operate from 4.5V to 15.5V, which is a slightly narrower range. AD8642ARZ operates from 5V to 26V. If the application requires operation below 4.5V or above 15.5V, LMC6082 series substitution is not compatible. If the application requires operation above 16V, only AD8642ARZ is suitable.

Q: What operating temperature range considerations apply to substitution?

A: The TLC2272AMD operates from -55°C to 125°C. LMC6082 series parts operate from -40°C to 85°C, which is a narrower range. AD8642ARZ operates from -40°C to 125°C. Applications requiring operation below -40°C are compatible only with TLC2272AMD. Applications requiring operation above 85°C are compatible with TLC2272AMD and AD8642ARZ but not LMC6082 series.

Q: How do output current specifications affect circuit design?

A: The TLC2272AMD provides 50mA output current per channel. LMC6082 series provides 34mA per channel. AD8642ARZ provides 12mA per channel. Applications requiring output currents exceeding 12mA per channel must use TLC2272AMD or LMC6082 series. Applications with output current requirements below 12mA can use any substitute.

Q: What inventory considerations should guide substitute selection?

A: LMC6082AIMX/NOPB has 2700 units in stock (Active status). LMC6082IMX/NOPB has 2165 units in stock (Active status). AD8642ARZ has 5400 units in stock (Active status). For immediate availability and long-term supply assurance, AD8642ARZ offers the highest inventory level. For CMOS technology preference with Active status, LMC6082AIMX/NOPB is recommended.
