Engineering Selection Recommendations
Primary Recommendation: TLV2241IDR
The TLV2241IDR is the active production equivalent manufactured by Texas Instruments. This device maintains identical electrical specifications to the obsolete TLV2241ID, including slew rate (0.002 V/µs), gain bandwidth product (5.5 kHz), input bias current (100 pA), input offset voltage (600 µV), and supply current (1 µA). The supply voltage range (2.5 V to 12 V) and operating temperature range (-40°C to 85°C) are identical. Both devices are ROHS3 compliant with MSL 1 rating. The only functional difference is packaging format: TLV2241IDR is supplied in Tape & Reel format for automated assembly processes. This part is currently in active production status with 3400 units in stock.
Secondary Recommendations: Advanced Linear Devices Inc. Series
The ALD1726SAL and ALD1726GSAL devices provide the closest electrical performance match among Advanced Linear Devices alternatives, with supply current of 25 µA and output current of 200 µA matching the TLV2241ID specifications. These parts operate within the 2 V to 10 V supply range and 0°C to 70°C temperature range. The ALD1726 series exhibits lower slew rate (0.17 V/µs) and reduced gain bandwidth product (400 kHz) compared to the TLV2241ID, suitable for applications not requiring high-speed performance.
The ALD1721SAL offers superior input offset voltage (50 µV) and maintains low supply current (110 µA), appropriate for precision measurement applications. The ALD1722SAL provides higher output current capability (8 mA) and faster slew rate (2.8 V/µs) for applications requiring increased drive capability.
All Advanced Linear Devices alternatives are ROHS3 compliant with MSL 1 rating and are currently in active production status.
Temperature Range Consideration
Applications requiring operation below 0°C or above 70°C must use TLV2241IDR, as all Advanced Linear Devices alternatives are limited to 0°C to 70°C operating range.
Supply Voltage Consideration
Applications requiring supply voltages above 10 V must use TLV2241IDR, which supports up to 12 V. Advanced Linear Devices alternatives are limited to 10 V maximum supply voltage.
Frequently Asked Questions (FAQ)

A: Yes. TLV2241IDR is the active production equivalent of TLV2241ID. Both devices share identical electrical specifications, package configuration (8-SOIC), and pin assignments. The primary difference is packaging format: TLV2241IDR is supplied in Tape & Reel format for automated assembly, while TLV2241ID was supplied in tube packaging. No circuit modifications are required.
Q: What are the key differences between TLV2241IDR and the Advanced Linear Devices alternatives?
A: The primary differences are operating temperature range and supply voltage limits. TLV2241IDR operates from -40°C to 85°C and supports supply voltages up to 12 V. Advanced Linear Devices alternatives operate from 0°C to 70°C with maximum supply voltage of 10 V. Additionally, electrical performance characteristics differ: TLV2241IDR has lower slew rate (0.002 V/µs) and lower gain bandwidth product (5.5 kHz) compared to most ALD alternatives, making it suitable for low-speed, low-power applications.
Q: Which Advanced Linear Devices part should I select for precision applications?
A: The ALD1721SAL offers the lowest input offset voltage (50 µV) among the Advanced Linear Devices alternatives, making it suitable for precision measurement and instrumentation applications. The ALD1722SAL provides the next best offset voltage specification (25 µV) with higher output current capability (8 mA).
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed—TLV2241IDR and all Advanced Linear Devices alternatives (ALD1721GSAL, ALD1721SAL, ALD1722GSAL, ALD1722SAL, ALD1726GSAL, ALD1726SAL)—are ROHS3 compliant with MSL 1 (Unlimited) rating.
Q: What is the difference between ALD1721GSAL and ALD1721SAL?
A: Both devices share identical electrical specifications and package configuration. The primary difference is input offset voltage: ALD1721GSAL specifies 150 µV, while ALD1721SAL specifies 50 µV. Selection depends on offset voltage requirements for the specific application.
Q: Can Advanced Linear Devices parts be used in applications requiring -40°C operation?
A: No. All Advanced Linear Devices alternatives are rated for 0°C to 70°C operating temperature range. Applications requiring operation at -40°C must use TLV2241IDR, which is rated for -40°C to 85°C.
Q: What is the maximum supply voltage for Advanced Linear Devices alternatives?
A: All Advanced Linear Devices alternatives (ALD1721, ALD1722, ALD1726 series) are rated for maximum supply voltage of 10 V. Applications requiring supply voltages above 10 V must use TLV2241IDR, which supports up to 12 V.
Q: Are the 8-SOIC packages for all parts physically identical?
A: Yes. All substitute parts use the 8-SOIC package with 0.154" (3.90 mm) width. The physical package dimensions and pin assignments are identical, enabling direct PCB layout compatibility.
Q: What is the difference between Tape & Reel and Tube packaging?
A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly processes, where components are supplied on continuous tape in reels. Tube packaging is used for manual assembly or lower-volume production. Both packaging formats contain identical components; the difference is in delivery and handling format only.
