CS4354

5V Stereo Audio D/A Converter with 2V_RMS Line Out

概要

製品概要

The CS4354 is a 24-bit, 192kHz stereo audio D/A converter with an on-chip 2V_RMS line driver working from a single 5 V power supply.

This new DAC is a step up version of the CS4352 that required a 9 to 12V power supply. It is also a low cost version of the CS4353.

Based on a charge-pump architecture, the CS4354 outputs a 2V_RMS voltage without the need for high voltage regulator. The CS4354 also features a ground-centered output architecture, removing the need for external DC blocking capacitors and any pop prevention circuit. Therefore, this new generation DAC allows to greatly reduce the amount of external component count while making the design simpler.

The CS4354 is ideal for any application that requires a line-level output. For example, mainstream consumer products such as DTV, Blu-ray players, set-top boxes, video game consoles, DVD players and recorders, personal video recorders (PVRs) and DVD receivers.

The CS4354 achieves 101dB dynamic range and is available in a 14-pin SOIC package in both commercial grade only.
