TLV2444AIPWR Equivalent & Substitute Parts

Part Overview

The TLV2444AIPWR is an active linear amplifier integrated circuit manufactured by Texas Instruments, classified as a CMOS rail-to-rail operational amplifier with four independent circuits in a 14-TSSOP surface mount package. The device is currently in active production status with 3053 units available in new original inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the amplifier category. Substitution becomes necessary when the primary part is unavailable, when supply chain constraints exist, or when design requirements permit operation within the performance envelope of alternative qualified devices.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2444AIPWR is determined by strict alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width) to ensure direct PCB footprint compatibility without layout redesign.

Circuit Configuration: The substitute must provide four independent amplifier circuits to maintain functional equivalence in multi-channel applications.

Output Architecture: Rail-to-rail output capability is required to preserve signal swing characteristics across the full supply voltage range.

Supply Voltage Range: The substitute must operate within or encompass the 2.7 V to 10 V supply span of the primary device. Substitutes with extended maximum supply ratings remain compatible provided minimum supply voltage does not exceed 2.7 V.

Operating Temperature Range: The substitute must support the -40°C to 85°C operating window. Extended temperature ranges are acceptable.

Regulatory Compliance: Both devices must maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity classification to ensure manufacturing process compatibility and long-term reliability.

The AD8040WARUZ-REEL7 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Substitution Eligibility: The AD8040WARUZ-REEL7 is a qualified substitute for the TLV2444AIPWR based on matching package geometry, circuit count, output architecture, and regulatory compliance status. Both devices are ROHS3 compliant with MSL 1 moisture sensitivity classification, ensuring compatibility with standard manufacturing and assembly processes.

Supply Voltage Consideration: The AD8040WARUZ-REEL7 supports a maximum supply voltage of 12 V, which exceeds the TLV2444AIPWR specification of 10 V maximum. This extended rating does not create incompatibility; the substitute remains fully functional within the 2.7 V to 10 V operating window of the primary device.

Temperature Range Extension: The AD8040WARUZ-REEL7 operates to 125°C maximum, compared to 85°C for the TLV2444AIPWR. This extended upper temperature limit provides additional operational margin and does not affect substitution validity for applications within the -40°C to 85°C range.

Product Status: Both devices maintain active production status, ensuring continued availability and supply chain stability.

Regulatory Alignment: Both parts carry identical ROHS3 compliance and REACH unaffected status, with matching ECCN (EAR99) and HTSUS (8542.33.0001) classifications, confirming full regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the AD8040WARUZ-REEL7 be used as a direct replacement for the TLV2444AIPWR without PCB modifications?

A: Yes. Both devices use the identical 14-TSSOP package with matching physical dimensions (0.173", 4.40mm Width). The pin configuration supports direct footprint compatibility without layout redesign.

Q: What are the key differences in electrical performance between these two devices?

A: The AD8040WARUZ-REEL7 exhibits higher slew rate (63 V/µs versus 1.4 V/µs), higher input bias current (700 nA versus 1 pA), higher input offset voltage (1.6 mV versus 300 µV), higher supply current (1.4 mA versus 750 µA per four channels), and higher output current per channel (170 mA versus 50 mA). These differences reflect the general-purpose amplifier classification of the AD8040 versus the CMOS architecture of the TLV2444.

Q: Are there any supply voltage limitations when substituting the AD8040WARUZ-REEL7?

A: No. The AD8040WARUZ-REEL7 minimum supply voltage is 2.7 V, matching the TLV2444AIPWR. The extended maximum rating of 12 V (versus 10 V) does not restrict operation within the original device's 2.7 V to 10 V range.

Q: Do both devices meet the same regulatory and compliance requirements?

A: Yes. Both the TLV2444AIPWR and AD8040WARUZ-REEL7 are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity classification, maintain REACH unaffected status, and share identical ECCN and HTSUS codes.

Q: What is the operating temperature range for each device?

A: The TLV2444AIPWR operates from -40°C to 85°C. The AD8040WARUZ-REEL7 operates from -40°C to 125°C. The substitute supports the full temperature range of the primary device with additional margin at the upper limit.

Q: Are both devices available in tape and reel packaging?

A: Yes. Both the TLV2444AIPWR and AD8040WARUZ-REEL7 are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
