Introduction

The AK4619 is a 192 kHz audio codec. Its 4-channel, 24-bit ADC supports an analog gain amplifier. On the output side, the AK4619’s 4-channel, 32-bit DAC supports single-ended analog output. Pairing the AK4619 with one of AKM's automotive multi-core DSPs enables processing of both audio and voice, as required for modern car audio systems. The AK4619 supports ambient temperatures from -40°C to 105°C and is available in a space-saving 32-pin QFN package, making it a perfect fit for automotive head units and amplifiers.
