Engineering Selection Recommendations

Direct Equivalent (Identical Specifications):

The TLC2272ID is the primary direct substitute for the TLC2272QD. Both devices share identical electrical specifications including slew rate (3.6 V/µs), gain bandwidth product (2.25 MHz), supply voltage range (4.4 V to 16 V), and operating temperature range (-40°C to 125°C). The TLC2272ID is currently in active production status, providing long-term availability and supply chain continuity. Both parts are ROHS3 compliant with MSL 1 rating.

Automotive-Grade Alternatives:

For applications requiring automotive qualification and extended temperature operation (-40°C to 125°C), the TS912BIDT manufactured by STMicroelectronics qualifies as a functional substitute. This device maintains AEC-Q100 certification and automotive grade designation. The TS912BIDT operates across a wider minimum supply voltage range (2.7 V to 16 V) and provides higher output current capability (75 mA per channel). However, the TS912BIDT exhibits lower slew rate (1.3 V/µs) and gain bandwidth product (1.4 MHz) compared to the TLC2272QD. This device is in active production with substantial inventory availability.

General-Purpose Alternatives (Non-Automotive):

The AD8666ARZ-REEL manufactured by Analog Devices Inc. provides superior performance characteristics with higher gain bandwidth product (4 MHz) and output current capability (140 mA per channel). This general-purpose amplifier maintains rail-to-rail output and operates across the full -40°C to 125°C temperature range. However, the AD8666ARZ-REEL lacks automotive qualification and is classified as a general-purpose amplifier rather than CMOS topology. This device is suitable for non-automotive applications requiring enhanced bandwidth and output drive capability.

Lower-Performance Alternatives:

The LMC6082 series (LMC6082AIM/NOPB, LMC6082AIMX/NOPB, LMC6082IM/NOPB, LMC6082IMX/NOPB) and LMC662 series (LMC662AIM/NOPB, LMC662AIMX/NOPB) provide functional substitution with reduced performance specifications. These devices operate at reduced slew rates (1.5 V/µs and 1.1 V/µs respectively) and lower gain bandwidth products (1.3 MHz and 1.4 MHz respectively). Operating temperature is limited to -40°C to 85°C, restricting use in extended temperature applications. These alternatives are suitable for applications where the TLC2272QD's performance specifications exceed design requirements and cost optimization is prioritized.

Product Status Considerations:

Applications requiring immediate component procurement should prioritize parts with active production status: TLC2272ID, LMC6082AIMX/NOPB, LMC6082IMX/NOPB, LMC662AIM/NOPB, LMC662AIMX/NOPB, AD8666ARZ-REEL, and TS912BIDT. The LMC6082IM/NOPB is designated as Last Time Buy, indicating limited future availability. The LMC6082AIM/NOPB is classified as obsolete.

Frequently Asked Questions (FAQ)

Q: Can the TLC2272ID be used as a direct replacement for the TLC2272QD?

A: Yes. The TLC2272ID is a direct equivalent with identical electrical specifications, package form factor, and operating temperature range. Both devices are CMOS dual-channel amplifiers in 8-SOIC packages with rail-to-rail output, 3.6 V/µs slew rate, and 2.25 MHz gain bandwidth product. The TLC2272ID is currently in active production, providing supply continuity for the obsolete TLC2272QD.

Q: What is the primary difference between the TLC2272QD and the LMC6082 series?

A: The LMC6082 series exhibits significantly lower slew rate (1.5 V/µs versus 3.6 V/µs) and reduced gain bandwidth product (1.3 MHz versus 2.25 MHz). Additionally, the LMC6082 series operates at a maximum temperature of 85°C, limiting use in applications requiring the full -40°C to 125°C range. The LMC6082 series is suitable for applications where performance specifications exceed design requirements.

Q: Is the TS912BIDT suitable for automotive applications?

A: Yes. The TS912BIDT maintains AEC-Q100 qualification and automotive grade designation, making it suitable for automotive applications. However, the device operates at reduced slew rate (1.3 V/µs) and gain bandwidth product (1.4 MHz) compared to the TLC2272QD. The TS912BIDT provides extended supply voltage range capability (2.7 V minimum) and higher output current (75 mA per channel).

Q: Can the AD8666ARZ-REEL replace the TLC2272QD in all applications?

A: The AD8666ARZ-REEL provides superior performance with higher gain bandwidth product (4 MHz) and output current capability (140 mA per channel). However, this device is classified as a general-purpose amplifier and lacks automotive qualification. The AD8666ARZ-REEL is suitable for non-automotive applications where enhanced performance is beneficial. Applications requiring automotive certification must use AEC-Q100 qualified alternatives.

Q: What packaging options are available for substitute parts?

A: All substitute parts maintain the 8-SOIC (0.154", 3.90mm Width) surface mount package form factor, ensuring mechanical compatibility. Packaging configurations vary by part number: Tube, Cut Tape (CT) & Digi-Reel®, and Bulk. Selection should be based on procurement volume and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of the TLC2272QD.

Q: Which substitute provides the lowest power consumption?

A: The TS912BIDT provides the lowest supply current at 230 µA (x2 Channels), compared to the TLC2272QD at 2.4 mA. The LMC662 series provides intermediate power consumption at 750 µA (x2 Channels). Power consumption selection should be balanced against performance requirements and operating temperature constraints.

Q: What is the minimum supply voltage requirement for each substitute?

A: The TLC2272QD and TLC2272ID require 4.4 V minimum. The LMC6082 series and LMC662 series require 4.5 V and 4.75 V respectively. The AD8666ARZ-REEL requires 5 V minimum. The TS912BIDT operates at the lowest minimum supply voltage of 2.7 V, providing flexibility for low-voltage applications.
