TAS5716PAP Equivalent & Substitute Parts

Part Overview

The TAS5716PAP is a Class D audio amplifier IC manufactured by Texas Instruments, configured as a dual/quad channel stereo or quad amplifier with 20.6W output power per channel at 8Ω load. The device integrates digital audio inputs (I2C, I2S), mute control, short-circuit and thermal protection, shutdown functionality, and volume control in a 64-HTQFP surface mount package.

The TAS5716PAP is designated as Last Time Buy, indicating end-of-life status. Identification of equivalent substitute parts is necessary to ensure design continuity and maintain supply chain availability for new production runs and ongoing support of existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAS5716PAP requires evaluation of the following critical parameters:

Channel Configuration: The TAS5716PAP supports 2-Channel (Stereo) or 4-Channel (Quad) operation. Substitute parts must support at least stereo operation to maintain functional compatibility in standard audio applications.

Output Power Specification: The TAS5716PAP delivers 20.6W per channel at 8Ω load. Substitute parts must meet or exceed this power specification at the same load impedance to ensure equivalent performance.

Supply Voltage Range: The TAS5716PAP operates from 10V to 26V. Substitute parts must support this voltage window or a compatible range that encompasses typical application requirements.

Digital Interface Support: The TAS5716PAP includes I2C and I2S digital audio inputs. Substitute parts must provide equivalent digital interface capability for seamless integration into existing audio signal chains.

Protection and Control Features: The TAS5716PAP integrates short-circuit protection, thermal protection, shutdown control, mute function, and volume control. Substitute parts should provide equivalent protection and control functionality.

Package and Mounting: The TAS5716PAP uses 64-TQFP surface mount packaging. Substitute parts may use alternative surface mount packages provided they are compatible with existing PCB layouts or acceptable for redesign.

Compliance and Certifications: Both parts must maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification).

Parameter Comparison

Engineering Selection Recommendations

TAS5805MPWPR as Primary Substitute

The TAS5805MPWPR is designated as the manufacturer-recommended substitute for the TAS5716PAP. Both devices are Class D amplifiers manufactured by Texas Instruments with ROHS3 compliance and equivalent regulatory classification (REACH Unaffected, EAR99).

Compatibility Assessment

The TAS5805MPWPR supports 2-Channel (Stereo) operation, meeting the minimum channel requirement for standard audio applications. Output power at 8Ω load is 23W per channel, exceeding the TAS5716PAP specification of 20.6W, providing improved performance margin.

Supply voltage range of the TAS5805MPWPR (4.5V ~ 26.4V) encompasses the TAS5716PAP operating window (10V ~ 26V). The extended lower voltage limit provides additional design flexibility.

Package Consideration

The TAS5805MPWPR uses 28-PowerTSSOP packaging versus the 64-TQFP of the TAS5716PAP. This represents a significant package change requiring PCB layout redesign. However, the smaller footprint and reduced pin count may provide space and cost benefits in new designs.

Feature Differences

The TAS5716PAP specifies digital input features (I2C, I2S), mute, and volume control. The TAS5805MPWPR parameter set provided does not explicitly list these features. Design verification is required to confirm feature parity for applications dependent on these control functions.

Product Status Advantage

The TAS5805MPWPR maintains Active product status, ensuring long-term availability and supply continuity compared to the Last Time Buy status of the TAS5716PAP.

Frequently Asked Questions (FAQ)

Q: Can the TAS5805MPWPR directly replace the TAS5716PAP in existing designs?

A: Direct replacement is not possible due to package incompatibility. The TAS5716PAP uses 64-TQFP (10x10mm) while the TAS5805MPWPR uses 28-PowerTSSOP. PCB layout redesign is required. Additionally, the TAS5805MPWPR supports maximum 2-Channel (Stereo) operation, not 4-Channel (Quad), limiting its use in quad-channel applications.

Q: What is the output power difference between these parts?

A: At 8Ω load, the TAS5805MPWPR delivers 23W per channel compared to 20.6W for the TAS5716PAP, representing approximately 12% higher output power. This provides improved performance margin for audio applications.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the TAS5716PAP and TAS5805MPWPR are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What is the minimum supply voltage for each part?

A: The TAS5716PAP requires minimum 10V supply voltage. The TAS5805MPWPR operates from 4.5V minimum, providing greater flexibility for low-voltage applications.

Q: Can the TAS5805MPWPR be used in quad-channel audio systems?

A: No. The TAS5805MPWPR supports only 1-Channel (Mono) or 2-Channel (Stereo) configuration. Applications requiring 4-Channel (Quad) operation cannot use this substitute without system redesign.

Q: What is the operating temperature range difference?

A: The TAS5716PAP operates from 0°C to 85°C. The TAS5805MPWPR extends the lower limit to -25°C, providing operation in wider temperature environments.

Q: Is the TAS5805MPWPR available in higher quantities?

A: Yes. The TAS5805MPWPR shows 21,400 pieces in stock compared to 890 pieces for the TAS5716PAP, indicating superior supply availability.
