Asahi Kasei Microdevices Corporation, (AKM), has developed a 6ch A/D converter, (ADC), the AK5736 for microphones in Active Noise Cancellation, (ANC *), systems implemented in car audio. The AK5736 features the low latency of 4.3 [1/fs] required for high speed processing with built-in capability to supply microphone power internally. The AK5736 also has a diagnostic function to monitor microphone connection. As a new feature, the AK5736 has an analog gain circuit setting to set a high gain level thus keeping high.
This product is an upgrade of the AK5730, a 4ch ADC for microphones, released in 2014.
* Active Noise Cancellation
The AK5736 features 4.3 [1/fs] low latency signal processing. This is perfect for an ANC system requiring real time processing.
This product can supply a maximum of 15mA per channel per microphone. External microphone power supplies are unnecessary.
The AK5736 integrates, “Diagnostic function”, monitoring for microphone or harness connections. In response to customer requests for amplifier units and head units, high accuracy diagnostic mode detecting with 12-bit accuracy has been newly added in addition to the simple diagnostic mode monitoring with 100mV accuracy.
