AK4332ECB Digital-to-Analog Converter

AKM's AK4332ECB is a 32-bit mono portable audio DAC with a built-in headphone amplifier optimized for true-wireless earphones and true-wireless stereo (TWS). The AK4332ECB supports both high-quality sound and ultra-low power consumption, all while integrated into an ultra-small 30-pin CSP package.

The AK4332ECB achieves a high performance of -101 dB THD+N and 109 dB SNR with one of the industry's most advanced levels of ultra-low power consumption at 2.8 mW. This enables TWS playback for long periods of time with high-quality sound. Even lower levels of power consumption are achieved by executing digital signal processing of the digital filtering and ΔΣ modulation with a Bluetooth SoC which utilizes small-geometry transistors.

Features

• High performance of -101 dB THD+N with only 2.8 mW power consumption
• VELVET SOUND technology is optimized in pursuing high-quality sound and high-performance for TWS
• Capable of achieving even lower power consumption with support of a 1-bit PDM signal

Applications

• True-wireless earphones
• True-wireless stereo (TWS)
