TAS5010IPFBG4

Audio Special Purpose Overview

The TAS5010IPFBG4 is a stereo PCM-PWM modulator from Texas Instruments, designed as part of the TDAA system with the TAS5100 power stage. It accepts serial digital audio inputs and converts them to 3.3-V PWM signals. The device supports 16-, 20-, or 24-bit data formats at sampling rates up to 192 kHz. Key electrical parameters include a 96-dB dynamic range, THD+N less than 0.08%, and 90% power efficiency into an 8-ohm load. It operates on a single 3V to 3.6V supply within an industrial temperature range of -40°C to 85°C.

Audio Special Purpose Feature Summary

• Equibit technology for low-distortion PCM-to-PWM modulation
• Integrated low-jitter PLL and digital interpolation filter
• Supports IIS, DSP, right/left-justified serial interfaces
• Hardware mute and clicks/pops reduction features

Audio Special Purpose Applications

• Car Audio Amplifiers and Head Units
• Home Theater Systems
• DVD-Audio Players
• Mini/Micro Component Systems

Audio Special Purpose Procurement Notes

Verify the G4 suffix indicates RoHS compliance and lead-free construction. Confirm the IPFB package variant matches the required 48-TQFP footprint. Ensure the automotive grade (-40°C to 85°C) aligns with the target application environment requirements.

Audio Special Purpose Selection Notes

Select this component when a high-efficiency digital audio front-end is needed. It requires pairing with a TAS5100 H-bridge power stage. Verify interface compatibility (IIS/DSP) via MOD pins. Ensure the system clock frequency matches the desired sampling rate (e.g., 11.2896 MHz for 44.1 kHz).

Audio Special Purpose Part Context

This device belongs to the TAS5000/TAS5100 True Digital Audio Amplifier family. It functions specifically as the modulator, while the TAS5100 serves as the power output stage. The G4 suffix denotes environmental compliance without altering functional specifications compared to the standard IPFB version.

Audio Special Purpose Replacement Considerations

TAS5010IPFB is the non-RoHS equivalent. TAS5010PFB is the commercial grade (0°C to 70°C) alternative.
