TAS5015PFB

Audio Special Purpose Overview

The TAS5015PFB is a stereo PCM-PWM modulator from the Texas Instruments TAS5000 family, designed for high-quality digital audio amplification. It operates on a 3V to 3.6V supply within a 48-TQFP (7x7 mm) package and supports an operating temperature range of 0°C to 70°C. The device delivers a dynamic range of 112dB with THD+N less than 0.01%. It accepts 16-, 20-, or 24-bit serial PCM data via DSP or I2S interfaces at sampling rates up to 192 kHz.

Audio Special Purpose Feature Summary

• Equibit technology-based PCM-to-PWM modulation providing 112dB dynamic range
• Supports sampling rates from 44.1 kHz to 192 kHz with external PLL
• Integrated 24-bit linear phase FIR interpolation filter
• Quiet mute function with clicks and pops reduction

Audio Special Purpose Applications

• Integrated amplifiers
• AV receivers
• Car audio systems

Audio Special Purpose Procurement Notes

The TAS5015PFB is classified as NRND (Not Recommended for New Designs). Verify current availability through authorized distributors and confirm that the component meets RoHS3 compliance standards before procurement.

Audio Special Purpose Selection Notes

Select this component for designs requiring a dedicated PCM-PWM modulator paired with discrete back-end power devices. Ensure the system design includes an external PLL for optimal performance and verify compatibility with the required serial audio interface formats.

Audio Special Purpose Part Context

This part belongs to the TAS5000 series of True Digital Audio Amplifiers. It functions as the digital front-end, converting PCM audio streams into PWM signals intended to drive discrete H-bridge power stages.

Audio Special Purpose Replacement Considerations

The TAS5015IPFB is the industrial temperature grade (-40°C to 85°C) equivalent. The suffix 'R' indicates a tape and reel packaging option (e.g., TAS5015PFBR).

Audio Special Purpose FAQ

What is the maximum supported sampling rate?

The device supports sampling rates up to 192 kHz in quad-speed mode.

How is the de-emphasis filter configured?

De-emphasis is enabled via the DEM_EN pin and selected for 44.1 kHz or 48 kHz using the DEM_SEL pin.

What is the quiet mute state behavior?

In quiet mute mode, the differential PWM outputs maintain a 50% duty cycle rather than hard muting.
