TIPCM5100APWR
Overview
The PCM5100APWR is a high-performance, 2-channel 32-bit audio DAC designed for line-level output applications up to 384kHz. It features an integrated charge pump that generates a ground-biased output, allowing for 2.1-VRMS signals without the need for bulky DC-blocking capacitors. The device includes an internal PLL to generate the system clock (SCK) from the bit clock (BCK), simplifying the interface with modern microcontrollers and SoCs.
Why Choose This Part
This DAC eliminates the cost and board space of DC-blocking capacitors by utilizing a DirectPath output driver that provides a ground-centered 2.1-VRMS signal. It simplifies hardware design by automatically generating the internal system clock from the BCK line, and it includes an intelligent muting system with a 120-dB SNR for pop-free performance during power cycles or sample rate changes.
Applications
Key Specifications
Getting Started
To evaluate this DAC, use the PCM5100AEVM-U evaluation module which connects via USB for rapid prototyping. Configuration is handled through hardware pins, so no I2C or SPI software overhead is required; simply provide I2S or Left-Justified PCM data and power within the 1.65V to 3.46V range.
