The AK4543VQ is an 18-bit high-performance audio codec from Asahi Kasei Microdevices, compliant with the Audio Codec '97 Rev 2.1 specification. It integrates two independent ADC channels and two DAC channels, supporting stereo line input and output along with multiple mono inputs. The device operates at a fixed 48kHz sampling rate and delivers excellent audio performance with 90dBA signal-to-noise ratio for both A/D and D/A paths, 89dBA for the D/A plus mixer path, and 95dBA for analog through. Power consumption is typically 200mW under full operation with analog supply at 5.0V and digital supply at 3.3V or 5.0V. The AK4543VQ communicates via the AC'97 serial link interface and supports primary or secondary codec operation for multi-codec configurations. It is housed in a compact 48-lead LQFP package for surface mount assembly. The device is pin-compatible with the earlier AK4540 and AK4542, though software changes may be required to utilize the additional features of the AK4543.
The AK4543VQ has 18-bit resolution for both ADC and DAC.
The sampling rate is 48 kHz.
The ADC SNR is 90 dBA, DAC SNR is 90 dBA, DAC+Mixer SNR is 89 dBA, and analog through SNR is 95 dBA.
Analog supply is 5.0 V nominal. Digital supply can be 3.3 V or 5.0 V.
The AK4543VQ is available in a 48-lead LQFP package.
RoHS compliance is marked as RoHS3 Compliant in the database, but this is unverified and low confidence. The datasheet from 1999 does not mention RoHS.
The AK4543VQ uses the AC'97 serial link interface.
