UPA2008 CMOS IC
3W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH DC VOLUME CONTROL

DESCRIPTION​

The UTC UPA2008 is a third generation 5-V class-D amplifier which provides precise DC volume control, lower supply current, lower noise floor, higher efficiency, smaller packaging, and fewer external components. Designed using a new filter-free class-D modulation technique, the UTC UPA2008 is capable of directly driving the speakers, without needing a low-pass output filter consisting of two inductors and three capacitors per channel.
Eliminating this output filter saves approximately 30% in system cost and 75% in PCB area.
The UTC UPA2008 improves the chip-level shutdown control, 1μA total supply current making the device ideal for battery-powered applications. It also protects the chip from being destroyed by over temperature and short current failure. To save battery power for more essential devices when battery voltage drops to low levels, undervoltage shutdown is designed in the UTC UPA2008.
In applications, class-D amplifier for LCD projectors, LCD monitors, powered speakers, the UTC UPA2008 is also suitable for battery operated and space constrained systems.

UPA2008 CMOS IC
帶直流音量控制的 3W 立體聲 D 類音頻功率放大器

說明

UTC UPA2008 是第三代 5V D 類放大器,可提供精確的直流音量控制、更低的電源電流、更低的本底噪聲、更高的效率、更小的封裝和更少的外部組件。 UTC UPA2008 採用新的無濾波器 D 類調製技術設計,能夠直接驅動揚聲器,無需每個通道由兩個電感器和三個電容器組成的低通輸出濾波器。
取消此輸出濾波器可節省大約 30% 的系統成本和 75% 的 PCB 面積。
UTC UPA2008 改進了芯片級關斷控制,1μA 總電源電流使該器件非常適合電池供電應用。它還可以保護芯片免受過熱和短路電流故障的破壞。為了在電池電壓降至低電平時為更重要的設備節省電池電量,UTC UPA2008 中設計了欠壓關斷功能。
在 LCD 投影儀、LCD 顯示器、有源揚聲器的 D 類放大器應用中,UTC UPA2008 也適用於電池供電和空間受限的系統。
