Description
YDA145-PZE7 is a high-efficiency digital audio power amplifier IC in the IC Chips category. It operates on a 12V single supply voltage and can configure an audio power amplifier with a maximum output of 9.5W (RL=8Ω) × 2ch or 19W (RL=4Ω) × 1ch with a single chip. It features the "Pure Pulse Direct Speaker Drive Circuit" that reduces distortion and noise on the signal, offering low distortion rate characteristics and low noise characteristics compared to other digital amplifier ICs. The YDA145-PZE7 requires minimal external parts, as filters are no longer necessary depending on the use conditions.
