PCM5242RHBR

ADCs/DACs - Special Purpose Overview

The PCM5242RHBR is a stereo digital-to-analog converter (DAC) from Texas Instruments, housed in a 32-terminal QFN package. It features DirectPath technology with ground-biased differential outputs, eliminating the need for DC blocking capacitors. The device supports sampling rates up to 384 kHz and accepts 16-, 24-, and 32-bit audio data via I2S, left-justified, right-justified, or TDM interfaces. Key electrical specifications include an SNR of 114 dB and a THD+N of -108 dB. It operates on a single 3.3V analog supply and 1.8V or 3.3V digital supply.

ADCs/DACs - Special Purpose Feature Summary

• Integrated programmable miniDSP core for custom filters and dynamic range controls
• Built-in high-performance PLL generating SCK internally from BCK reference
• Intelligent muting system with soft ramp and analog mute achieving 120 dB mute SNR

ADCs/DACs - Special Purpose Applications

• Hi-Fi smartphones
• A/V receivers
• DVD and Blu-ray players
• HDTV receivers

ADCs/DACs - Special Purpose Procurement Notes

Verify the suffix RHBR indicates the reel packaging format. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range of -25°C to +85°C aligns with the specific application environment requirements before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a compact solution with integrated DSP capabilities is required. The DirectPath feature simplifies board layout by removing large output capacitors. Verify that the host processor supports the required PCM interface formats and that the power supply constraints match the 3.3V analog and 1.8V/3.3V digital requirements.
