Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2444CPWR is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 14-TSSOP surface mount configuration
• Package dimensions: 0.173" width, 4.40mm width specification
• Mounting type: Surface mount

Electrical Compatibility:

• Number of circuits: 4-channel configuration
• Output type: Rail-to-rail capability
• Supply voltage range: Minimum 2.7V, maximum voltage support of 10V or greater
• Operating temperature range: Support for 0°C to 70°C minimum

Regulatory & Environmental Compliance:

• RoHS3 compliance status
• Moisture sensitivity level MSL 1 (unlimited)
• Active product status

The AD8040WARUZ-REEL7 manufactured by Analog Devices Inc. satisfies all mechanical and electrical compatibility criteria. Both devices feature identical 14-TSSOP packaging, 4-circuit configuration, rail-to-rail output, and overlapping supply voltage specifications. Both maintain Active product status and ROHS3 compliance with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TLV2444CPWR remains the preferred component for applications where the specified electrical characteristics are required. The device maintains Active product status with established supply chain availability and ROHS3 compliance certification.

Substitution Applicability:

The AD8040WARUZ-REEL7 serves as a functional substitute when the TLV2444CPWR is unavailable. Both devices share identical mechanical packaging (14-TSSOP), circuit count (4), output configuration (rail-to-rail), and minimum supply voltage (2.7V). Both maintain Active product status and ROHS3 compliance with MSL 1 rating.

Operational Differences:

The AD8040WARUZ-REEL7 exhibits higher performance specifications in slew rate (63V/µs versus 1.4V/µs), bandwidth capability (125 MHz -3dB bandwidth), and output current per channel (170 mA versus 50 mA). The AD8040WARUZ-REEL7 supports an extended operating temperature range (-40°C to 125°C versus 0°C to 70°C) and higher maximum supply voltage (12V versus 10V). Input bias current and input offset voltage are higher in the AD8040WARUZ-REEL7, and supply current consumption is increased.

Compliance Status:

Both parts maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and Active product status. Both are suitable for applications requiring regulatory compliance in these categories.

Frequently Asked Questions (FAQ)

Q: Can the AD8040WARUZ-REEL7 be used as a direct replacement for the TLV2444CPWR in all applications?

A: The AD8040WARUZ-REEL7 is mechanically and electrically compatible for pin-to-pin substitution due to identical 14-TSSOP packaging and 4-circuit configuration. However, the AD8040WARUZ-REEL7 exhibits different electrical performance characteristics, including higher slew rate, bandwidth, output current capability, and supply current consumption. Applications sensitive to power consumption, input offset voltage, or input bias current specifications require evaluation of the AD8040WARUZ-REEL7 performance parameters against design requirements.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the TLV2444CPWR and AD8040WARUZ-REEL7 utilize the 14-TSSOP package with 0.173" width and 4.40mm width specification. PCB layout and footprint compatibility are maintained.

Q: What is the supply voltage compatibility between these parts?

A: Both parts operate at a minimum supply voltage of 2.7V. The TLV2444CPWR supports a maximum of 10V, while the AD8040WARUZ-REEL7 supports 12V maximum. Applications operating within the 2.7V to 10V range are compatible with both devices. Applications requiring 10V to 12V operation require the AD8040WARUZ-REEL7.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the TLV2444CPWR and AD8040WARUZ-REEL7 maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and Active product status. Both are suitable for applications requiring these compliance certifications.

Q: What are the key electrical performance differences?

A: The AD8040WARUZ-REEL7 provides higher slew rate (63V/µs versus 1.4V/µs), higher -3dB bandwidth (125 MHz), higher output current per channel (170 mA versus 50 mA), and extended operating temperature range (-40°C to 125°C versus 0°C to 70°C). The TLV2444CPWR provides lower input bias current (1 pA versus 700 nA), lower input offset voltage (300 µV versus 1.6 mV), and lower supply current consumption (750 µA versus 1.4 mA for 4 channels).

Q: Is the operating temperature range a limiting factor for substitution?

A: The TLV2444CPWR operates from 0°C to 70°C, while the AD8040WARUZ-REEL7 operates from -40°C to 125°C. Applications requiring operation below 0°C or above 70°C cannot use the TLV2444CPWR. Applications operating within the 0°C to 70°C range are compatible with both devices.

Q: What is the tape and reel packaging specification for both parts?

A: Both the TLV2444CPWR and AD8040WARUZ-REEL7 are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes. The packaging designation indicates surface mount configuration with standard reel specifications for pick-and-place equipment.
