PCM3794RHBT is an advanced version of the PCM3794 family of codecs from Nuvoton. It is designed for cost-sensitive applications that require stereo audio input and output capability. It is optimized for use in automobiles, industrial audio systems, medical audio systems and portable/wearable audio kits. It features programmable sample rates for great flexibility, low latency and integrated audio processing, so users can get the desired audio performance.

The PCM3794RHBT is a CMOS codec with I2S interface, stereo codec and digital microphone interface, which supports various audio functions including sample rate conversion, noise shaping filter and programmable gain control. The PCM3794RHBT supports up to 4 stereo I2S audio channels and two mono digital microphone channels. The PCM3794RHBT supports a sample rate up to 96kHz, and its high-speed digital microphone interface supports up to 32kHz sample rates

The PCM3794RHBT is designed to be easy to implement in a system and is integrated with a variety of audio-enhancement features. It includes a programmable gain control (PGC) that features four user-selectable gain steps. It also features a noise shaping filter (NSF) and a peak limiter (PL) that help reduce noise in the audio signal chain. Furthermore, the PCM3794RHBT supports sample rate conversion (SRC) that allows for different sample rates for input and output.

The PCM3794RHBT enables users to program all the audio functions, including sample rate, noise shaping filter, PGC and peak limiter, using an I2C interface. The codec also features an internal oscillator and can use an external crystal or clock source to adjust the sample rate.

The PCM3794RHBT is ideal for applications requiring a small and cost-effective stereo codec. The PCM3794RHBT offers low latency, wide dynamic range and wide range of adjustability. It also supports digital microphones, sample rate conversion and programmable gain control. This codec is an excellent choice for any audio application that needs low power consumption and reduced board footprint.
