ZHCSH30C August 2017 – April 2018 TAS5755M
PRODUCTION DATA.
The TAS5755M DAP device uses noise-shaping and customized nonlinear correction algorithms to achieve high power efficiency and high-performance digital audio reproduction. The DAP uses a fourth-order noise shaper to increase dynamic range and SNR in the audio band. The PWM section accepts 24-bit PCM data from the DAP and outputs two BTL PWM audio output channels.
The PWM section has individual-channel dc-blocking filters that can be enabled and disabled. The filter cutoff frequency is less than 1 Hz. Individual-channel de-emphasis filters for 44.1 kHz and 48 kHz are included and can be enabled and disabled.
Finally, the PWM section has an adjustable maximum modulation limit of 93.8% to 99.2%.
For a detailed description of using audio processing features like DRC and EQ, see the TAS5755EVM User's Guide (SLOU481) and TAS570X GDE Software Setup development tool documentation (SLOC124).
