TAS5010IPFBR

Audio Special Purpose Overview

The TAS5010IPFBR is a stereo PCM-PWM modulator from Texas Instruments, designed as part of the True Digital Audio Amplifier (TDAA) system. It accepts serial digital audio inputs and converts them into differential 3.3-V PWM signals for driving external power stages like the TAS5100. The device supports sampling rates up to 192 kHz with 16-, 20-, or 24-bit data formats. Key electrical parameters include a 96-dB dynamic range, THD+N less than 0.08%, and a supply voltage range of 3 V to 3.6 V. It operates within an ambient temperature range of -40°C to 85°C and is housed in a 48-TQFP package.

Audio Special Purpose Feature Summary

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

Audio Special Purpose Applications

• DVD-Audio systems
• Home theater amplifiers
• Car audio amplifiers and head units
• Mini/micro component systems

Audio Special Purpose Procurement Notes

Verify the 'R' suffix indicates Tape & Reel packaging containing 1000 units per reel. Confirm the IPFB variant meets the specified -40°C to 85°C operating temperature range. Ensure compatibility with 3.3 V logic levels for all digital inputs and outputs.

Audio Special Purpose Selection Notes

Select this component when designing a TDAA system requiring a dedicated digital modulator stage. It must be paired with a compatible power output device such as the TAS5100. Verify that the host processor can provide the required MCLK, SCLK, and LRCLK signals for the chosen master or slave mode configuration.

Audio Special Purpose Part Context

This device belongs to the TAS5010 family of True Digital Audio Amplifiers. The IPFB designation specifies the industrial temperature grade (-40°C to 85°C) and the 48-pin TQFP plastic quad flatpack housing. The 'R' suffix denotes the specific tape and reel packaging format used for automated surface-mount assembly.

Audio Special Purpose Replacement Considerations

TAS5010IPFBG4 is a lead-free version of the same functional device. TAS5010PFBR is the commercial temperature grade equivalent (-40°C to 70°C). No direct pin-compatible digital modulator replacements are documented.
