TAS5707PHP

Overview

The TAS5707PHP is a stereo digital audio power amplifier manufactured by Texas Instruments. It delivers 20.6 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a supply voltage range from 8 V to 24 V and features a Class-AB output stage. It utilizes a single I2S input interface and requires triple power supplies, including a dedicated 3.3 V digital supply. The component is housed in a 48-pin HTQFP package and supports surface mount installation. It functions within an operating temperature range of 0°C to +85°C.

Feature Summary

• Integrates digital equalization (EQ) and dynamic range compression (DRC) capabilities for signal processing.
• Supports I2S digital audio input interfaces for direct connection to digital sources.
• Provides high-fidelity stereo amplification with low distortion characteristics.

Applications

• Digital audio systems requiring integrated signal conditioning
• Stereo audio power amplification circuits
• Embedded audio devices with I2S connectivity

Procurement Notes

Verify the specific suffix 'PHP' against official Texas Instruments documentation to confirm pinout and electrical specifications, as variations exist within the TAS5707 family. Confirm RoHS compliance status and lead-free certification requirements for your assembly process. Ensure the design accommodates the required triple power supply rails, specifically the 3.3 V digital supply mentioned in datasheets. Validate that the HTQFP-48 package thermal performance meets system constraints under maximum load conditions.

Selection Notes

Select this component when a stereo digital amplifier with built-in EQ and DRC is required. It is suitable for applications needing 20 W output into 8 ohms with Class-AB efficiency characteristics. Consider the HTQFP-48 package size and the need for a separate 3.3 V digital supply rail during schematic design. Verify compatibility with I2S source devices and ensure adequate heat dissipation for the specified operating temperature range.

Part Context

The TAS5707PHP belongs to the Texas Instruments TAS5707 series of digital audio power amplifiers. This series integrates digital signal processing features such as equalization and dynamic range compression directly into the power amplifier stage. The device is designed for stereo applications, offering high output power with low distortion. It connects via I2S interfaces, simplifying integration with digital audio processors or microcontrollers.
