PA3332

UNISONIC TECHNOLOGIES CO., LTD PA3332 Preliminary 2.6W STEREO AUDIO AMPLIFIER  DESCRIPTION The UTC PA3332 is a stereo audio power amplifier. When the device is idle, it enters SHDN mode for some low current consumption applications. The current dissipation is thus reduced below 5μA. Mute function is included to mute the output. Operating on a 5V power supply, the UTC PA3332 is capable of driving a 4.0 Ω BTL load at a continuous average RMS output of 2.0W per channel with a less than 1% THD.％ There are two input paths, therefore, two different gain loops can be set in the same PCB. We could choose one of the two gain paths through the logic level of IN/IN pin. This increases the flexibility of the hardware design. In order to prevent the speakers from burned-out, the UTC PA3332 also has a function of maximum output power clamping is designed.  FEATURES * Including de-pop circuit * Output power at 1% THD+N, VDD=5V 2.0W/CH (TYP.) into a 4Ω Load 1.3W/CH (TYP.) into a 8Ω Load * Output power at 10% THD+N, VDD=5V 2.6W/CH (typical) into a 4Ω Load 1.6W/CH (typical) into a 8Ω Load * BTL mode (Bridge-Tied Load) * Maximum output power clamping circuitry contained * Mute and shutdown control available * Stereo input MUX  ORDERING INFORMATION Ordering Number PA3332G-N24-R Package HTSSOP-24 CMOS IC Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 9 QW-R502-488.b PA3332  PIN CONFIGURATION Preliminary CMOS IC Note: Recomm...
