TAS5707PHPR Equivalent & Substitute Parts

Part Overview

The TAS5707PHPR is a Class D stereo amplifier IC manufactured by Texas Instruments, designed for 2-channel audio amplification with 20.6W output power per channel at 8Ω load impedance. The device operates across a supply voltage range of 8V to 24V and integrates digital control interfaces including I2C and I2S protocols, along with comprehensive protection features such as short-circuit and thermal protection.

The TAS5707PHPR carries a product status designation of "Not For New Designs," indicating that Texas Instruments has discontinued recommendations for new circuit implementations. This status necessitates identification of equivalent or substitute components that maintain functional compatibility while offering active product support and extended lifecycle availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5707PHPR is determined by the following critical parameters that must be evaluated for functional compatibility:

Output Configuration Compatibility: The TAS5707PHPR operates as a dedicated 2-channel stereo amplifier. Substitute components must support 2-channel stereo operation to maintain circuit functionality without redesign.

Class D Topology: The amplifier utilizes Class D switching topology. Substitute parts must employ identical Class D architecture to preserve efficiency characteristics and control signal compatibility.

Supply Voltage Range: The operating supply voltage window of 8V to 24V defines the power delivery requirements. Substitute components must accommodate this voltage range or provide overlapping coverage.

Output Power Specification: The 20.6W per channel output at 8Ω load impedance establishes the power delivery requirement. Substitute parts must meet or exceed this specification at the same load impedance.

Digital Interface Support: The presence of I2C and I2S digital control interfaces indicates system-level integration requirements. Substitute components should maintain these interface capabilities.

Protection Features: Short-circuit and thermal protection mechanisms are integral to safe operation. Substitute parts should include equivalent protection functionality.

Package and Mounting: Surface mount packaging in a 48-pin configuration defines PCB integration constraints. Substitute components must be compatible with existing board layouts or require minimal redesign.

Product Status and Compliance: Active product status with current RoHS3 compliance ensures long-term availability and regulatory alignment.

Engineering Selection Recommendations

TAS5805MPWPR as Primary Substitute:

The TAS5805MPWPR is designated as the manufacturer-recommended substitute for the TAS5707PHPR. This component maintains Class D amplifier topology and supports 2-channel stereo operation, satisfying the core functional requirements of the original design.

Functional Advantages:

The TAS5805MPWPR delivers 23W per channel at 8Ω in stereo configuration, exceeding the TAS5707PHPR specification of 20.6W per channel. The expanded supply voltage range of 4.5V to 26.4V provides broader system integration flexibility compared to the 8V to 24V range of the original part.

Product Lifecycle Status:

The TAS5805MPWPR carries an "Active" product status designation, ensuring ongoing manufacturer support, continued availability, and compliance with current regulatory standards. This contrasts with the "Not For New Designs" status of the TAS5707PHPR, making it the appropriate choice for new circuit implementations and long-term production requirements.

Compliance and Certification:

Both components maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels, ensuring regulatory alignment and manufacturing process compatibility.

Package Consideration:

The TAS5805MPWPR utilizes a 28-pin PowerTSSOP package, which differs from the 48-pin PowerTQFP package of the TAS5707PHPR. This package change requires PCB layout modification and may affect thermal management characteristics. The smaller pin count and reduced package footprint may provide space optimization benefits in redesigned layouts.

Temperature Operating Range:

The TAS5805MPWPR extends the lower operating temperature limit to -25°C, compared to 0°C for the TAS5707PHPR. This expanded range accommodates applications requiring operation in lower temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWPR directly replace the TAS5707PHPR without PCB modifications?

A: Direct pin-for-pin replacement is not possible. The TAS5805MPWPR uses a 28-pin PowerTSSOP package while the TAS5707PHPR uses a 48-pin PowerTQFP package. PCB layout redesign is required for implementation of the substitute component.

Q: Does the TAS5805MPWPR support the same digital control interfaces as the TAS5707PHPR?

A: The provided specifications do not include detailed feature listings for the TAS5805MPWPR. Verification of I2C and I2S interface support requires consultation of the TAS5805MPWPR datasheet.

Q: What is the significance of the "Not For New Designs" status on the TAS5707PHPR?

A: This designation indicates that Texas Instruments has discontinued recommendations for new circuit implementations. The component may experience reduced availability, limited technical support, and eventual discontinuation. The TAS5805MPWPR, with "Active" status, is the appropriate selection for new designs.

Q: Are there thermal management differences between the two packages?

A: The 48-pin PowerTQFP and 28-pin PowerTSSOP packages have different thermal characteristics. The specific thermal performance of each package requires review of the respective datasheets and thermal modeling for the target application.

Q: Does the expanded supply voltage range of the TAS5805MPWPR affect circuit design?

A: The TAS5805MPWPR operates across 4.5V to 26.4V compared to the TAS5707PHPR range of 8V to 24V. This expanded range may allow operation at lower supply voltages if the application permits. Existing power supply designs operating within the 8V to 24V window remain compatible.

Q: What inventory considerations apply to these components?

A: The TAS5707PHPR has 455,400 pieces in stock as new original inventory. The TAS5805MPWPR has 21,400 pieces in stock. Long-term availability favors the TAS5805MPWPR due to its active product status.

Q: Are both components RoHS compliant?

A: Yes, both the TAS5707PHPR and TAS5805MPWPR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
