3 說明
TAS2770 是一款經優化后可高效驅動小型揚聲器的單聲道數字輸入 D 類音頻放大器。憑借出色的輸出功率、保護功能和封裝，TAS2770 成為智能揚聲器、藍牙揚聲器、家庭自動化設備、筆記本電腦和平板電腦的理想選擇。
該 D 類放大器能夠在 16V 電壓下向 4Ω 的負載提供 20W 的連續功率，在 16V 電壓下向 8Ω 的負載提供 15W 的連續功率，兩種情況下的 THD 都為 1%。4.5V 至 16V 的寬輸入電壓范圍和高輸出功率使該放大器具有出色的通用性，能夠與電池電源或線路供電系統配合使用。
欠壓保護器跟蹤峰值電壓，并自動將增益限制為可用電壓。該硬件實現的功能降低了放大器對系統電源的需求，從而防止音頻中斷和系統關斷。
TAS2770 可用作常規放大器或與基于主機的揚聲器保護算法配合使用。集成的揚聲器電壓和電流感應功能可通過 I2S 返回路徑將揚聲器狀況實時反饋到保護算法。
最多有 8 個器件可以通過任意一個 I2S/TDM + I2C 共享一個公共總線。
TAS2770 器件采用 26 引腳、0.4mm 間距 QFN 封裝，實現緊湊的 PCB 空間。
