DPA5V3F CMOS IC
2.8W FILTER-FREE MONO CLASS D AUDIO POWER AMPLIFIER
DESCRIPTION
FEATURES
DPA5V3F CMOS IC
2.8W FILTER-FREE MONO CLASS D AUDIO POWER AMPLIFIER
DESCRIPTION
The UTC DPA5V3F is a differential class-D BTL power amplifier. It can drive up to 2.2W into a 4Ω load and 1.4W into an 8Ω load at 5V. It achieves outstanding efficiency (88% typ.) compared to standard AB-class audio amps.
The gain of the device can be controlled via two external gain setting resistors. Pop & click reduction circuitry provides low on/off switch noise while allowing the device to start within 5ms. A standby function (active low) enables the current consumption to be reduced to 10nA typical.

DPA5V3F CMOS 積體電路
2.8W 無濾波單聲道 D 類音訊功率放大器
產品說明
UTC DPA5V3F 為差動式 D 類橋接負載（BTL）功率放大器。在 5V 電源下，可提供最高 2.2W 的輸出功率至 4Ω 負載，以及 1.4W 至 8Ω 負載。相較於傳統 AB 類音訊放大器，本產品展現出優異的效率（典型值達 88%）。
其增益可透過兩個外部電阻進行設定，內建的「Pop & Click」抑制電路可有效降低開關噪音，並在 5ms 內快速啟動。低態啟用的待機功能可使電流消耗降至典型值 10nA。
產品特性
