AKM Launches AK5705 Low Power 4-Channel 32-bit A/D Converter

Asahi Kasei Microdevices (AKM) has developed the AK5705, a low power consumption 4-channel 32-bit A/D converter (ADC) with a built-in transimpedance amplifier in addition to a low-noise microphone amplifier. The new AKM the AK5705 ADC is connectable to current output sensors, supports a sampling frequency of 384kHz, and achieves a dynamic range of 109dB, while consuming 43% less power than existing AKM products. The built-in AC coupling capacitor significantly reduces the mounting area including external components.

No more yelling at smart speakers. Texas Instruments (TI) introduced a new audio analog-to-digital converter (ADC) capable of capturing clear audio up to four times farther away than competing devices. The new TI Burr-Brown TLV320ADC5140 audio ADC enables far-field voice capture and achieves a 120-dB dynamic range for clear, high-fidelity audio in smart home applications. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance.
