TLV2444IPWR Equivalent & Substitute Parts

Part Overview

The TLV2444IPWR is an active linear amplifier integrated circuit manufactured by Texas Instruments, classified as a CMOS rail-to-rail operational amplifier with four independent circuits. The device is housed in a 14-pin TSSOP surface mount package and operates across a supply voltage range of 2.7V to 10V with an operating temperature range of -40°C to 85°C. The TLV2444IPWR maintains active product status and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute components are identified when equivalent functional performance can be achieved within the same package footprint and compatible electrical operating parameters. Alternative parts may be required due to inventory availability, supply chain considerations, or specific application performance requirements while maintaining circuit compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TLV2444IPWR are qualified based on the following substitution criteria:

Package Compatibility: The substitute part must utilize the same 14-TSSOP surface mount package with identical 0.173" (4.40mm) width to ensure direct PCB footprint compatibility without layout modifications.

Circuit Configuration: The substitute must provide four independent amplifier circuits within a single integrated circuit to maintain functional equivalence.

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 2.7V to 10V supply voltage specification of the primary part.

Mounting and Compliance: Surface mount technology with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1) ensures manufacturing process compatibility and regulatory alignment.

The AD8040WARUZ-REEL7 manufactured by Analog Devices Inc. satisfies all substitution criteria through identical package geometry, four-circuit configuration, rail-to-rail output, compatible supply voltage range, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV2444IPWR and AD8040WARUZ-REEL7 maintain active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, confirming suitability for current manufacturing and long-term supply chain stability.

The TLV2444IPWR is selected as the primary component when low-power operation and minimal input bias current are critical design requirements. The device operates within a 2.7V to 10V supply range with 750µA total supply current across four channels and 1 pA input bias current per channel.

The AD8040WARUZ-REEL7 serves as a qualified substitute when higher performance metrics are required. This device extends the maximum supply voltage to 12V, provides higher slew rate capability (63V/µs versus 1.4V/µs), and delivers increased output current per channel (170 mA versus 50 mA). The operating temperature range extends to 125°C, accommodating applications requiring elevated thermal performance.

Both components share identical package geometry, circuit count, and rail-to-rail output architecture, ensuring direct functional substitution within the same PCB layout without design modification.

Frequently Asked Questions (FAQ)

Q: Can the AD8040WARUZ-REEL7 be used as a direct replacement for the TLV2444IPWR in existing designs?

A: Yes. Both devices utilize the 14-TSSOP package with identical footprint dimensions, contain four independent amplifier circuits, and provide rail-to-rail output capability. The AD8040WARUZ-REEL7 operates within the TLV2444IPWR supply voltage range (2.7V to 10V) and maintains compatible compliance certifications. No PCB layout modifications are required for substitution.

Q: What are the key performance differences between these two parts?

A: The AD8040WARUZ-REEL7 provides higher slew rate (63V/µs versus 1.4V/µs), greater output current capability (170 mA versus 50 mA per channel), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The TLV2444IPWR offers lower input bias current (1 pA versus 700 nA) and lower supply current consumption (750µA versus 1.4mA for four channels).

Q: Are there supply voltage compatibility concerns when substituting these parts?

A: No. The AD8040WARUZ-REEL7 maximum supply voltage rating of 12V exceeds the TLV2444IPWR maximum of 10V. Both devices operate at the minimum 2.7V supply voltage. Circuits designed for the TLV2444IPWR supply range operate without modification using the AD8040WARUZ-REEL7.

Q: Do these parts require different PCB layout considerations?
