TAS5707APHP Equivalent & Substitute Parts

Part Overview

The TAS5707APHP is a Class D stereo amplifier IC manufactured by Texas Instruments, designed for 2-channel audio amplification with a maximum output power of 20.6W per channel at 8Ohm load impedance. The device operates across a supply voltage range of 8V to 24V and integrates digital audio interfaces including I2S and I2C control, along with comprehensive protection features such as short-circuit and thermal protection.

The TAS5707APHP carries a product status designation of "Not For New Designs," indicating that Texas Instruments has discontinued active development and support for this component. This status necessitates identification of equivalent substitute parts for applications requiring continued component availability or for new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5707APHP is determined by the following critical parameters:

Functional Compatibility Criteria:

• Amplifier type classification (Class D topology)
• Channel configuration capability (stereo operation)
• Output power delivery specifications
• Supply voltage operating range overlap
• Digital interface support (I2S, I2C)
• Protection feature integration

Physical and Environmental Criteria:

• Surface mount mounting type
• Operating temperature range compatibility
• Moisture sensitivity level (MSL)
• RoHS and REACH compliance status

The TAS5805MPWP qualifies as a substitute based on its Class D amplifier architecture, stereo operation capability, overlapping supply voltage range, surface mount configuration, and equivalent compliance certifications. The substitute part operates across an extended temperature range and provides higher maximum output power specifications, making it suitable for applications previously served by the TAS5707APHP.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TAS5707APHP is designated as "Not For New Designs," which indicates that Texas Instruments has concluded active support and development for this component. The TAS5805MPWP carries an "Active" product status, confirming ongoing manufacturer support, availability, and compliance maintenance.

Compliance and Certification: Both the TAS5707APHP and TAS5805MPWP maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. Both components share identical MSL ratings of 3 (168 Hours), indicating equivalent moisture sensitivity handling requirements during manufacturing and assembly processes.

Supply Voltage and Power Delivery: The TAS5805MPWP operates across an extended supply voltage range (4.5V ~ 26.4V) compared to the TAS5707APHP (8V ~ 24V), providing broader application flexibility. In stereo configuration at 8Ohm load impedance, the TAS5805MPWP delivers 23W per channel, exceeding the TAS5707APHP specification of 20.6W per channel.

Temperature Operating Range: The TAS5805MPWP supports an extended operating temperature range (-25°C ~ 85°C) relative to the TAS5707APHP (0°C ~ 85°C), enabling deployment in applications requiring lower temperature operation.

Package Transition: The TAS5805MPWP utilizes a 28-PowerTSSOP package, representing a reduction in pin count and physical footprint compared to the 48-PowerTQFP package of the TAS5707APHP. PCB layout redesign is required for package migration.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWP directly replace the TAS5707APHP without PCB modifications?

A: No. The TAS5805MPWP uses a 28-PowerTSSOP package while the TAS5707APHP uses a 48-PowerTQFP package. Pin assignments differ, requiring PCB layout redesign and schematic modifications. However, both devices share Class D amplifier architecture and stereo operation capability, making functional substitution feasible with appropriate circuit redesign.

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

A: The TAS5805MPWP provides higher maximum output power (23W x 2 @ 8Ohm versus 20.6W x 2 @ 8Ohm), operates across a wider supply voltage range (4.5V ~ 26.4V versus 8V ~ 24V), and supports an extended lower temperature limit (-25°C versus 0°C). The TAS5707APHP integrates I2C and I2S digital interfaces; the TAS5805MPWP feature set was not specified in the provided data.

Q: Are there compliance or regulatory concerns with substituting the TAS5805MPWP for the TAS5707APHP?

A: No compliance concerns exist. Both components maintain ROHS3 compliance and REACH unaffected status. Both share identical MSL ratings, ensuring equivalent handling requirements during manufacturing and assembly.

Q: Why is the TAS5707APHP marked as "Not For New Designs"?

A: This designation indicates that Texas Instruments has concluded active development and support for the TAS5707APHP. New designs should utilize the TAS5805MPWP or other active-status alternatives to ensure long-term component availability and manufacturer support.

Q: What inventory considerations apply to these parts?

A: The TAS5707APHP has 998 pieces available in stock with "Not For New Designs" status, indicating limited future availability. The TAS5805MPWP has 2072 pieces in stock with "Active" product status, confirming ongoing availability and supply chain support.

Q: Does the TAS5805MPWP support the same digital interfaces as the TAS5707APHP?

A: The TAS5707APHP integrates I2C and I2S digital audio interfaces. The feature set for the TAS5805MPWP was not specified in the provided technical data. Detailed interface compatibility must be verified through the respective device datasheets.
