The ES8323S with Codec ICs QFN-28 RoHS is a low-power CMOS audio processor circuit manufactured by Everest Semiconductor. It is conveniently housed in a 28-lead, 4x4mm Quad Flat No-Lead (QFN) package, with on-chip DC-DC converters and LDO voltage regulators. The ES8323S supports multiple sampling rates, including 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz. This IC also features differential analogue and digital mic inputs, which enable two mono mics with or without bias voltages. Its amplifiers provide both differential and single-ended outputs at low-power consumption for line-out, headphone-out, and speaker drivers. Additionally, it includes an on-board audio interface connected via an I2S bus. The ES8323S is a perfect choice for a variety of audio applications, such as digital cameras, MP4 players, MP3 players, and portable audio players.
