Stereo audio amplifier PAM8403, Class D 2x3W
Applications: -amplifier for televisions -home cinema -any kind of audio systems -MP3/MP4 players -replacement of the final stages of different devices Advantages: -high efficiency (efficiency ratio) -current protection -low supply voltage protection - Typ. 2.5 -ideal for powering a 3.6V Li-Ion battery -very small non-linear distortion from 20Hz to 30kHz -very low current in standby mode -is not affected by large ripples in the supply voltage -very little heat released Attention: 1. The direction of the supply voltage should not be confused, and it should not exceed 6V even for a short time. 2. It is recommended that the audio input cables are shielded. 3. The output stage of the circuit is full bridge (BTL). The output negatives cannot be connected at one point, otherwise you risk burning the integrated circuit. MAIN PARAMETERS: ·Work class CLASS D (CLASS D) ·Operating voltage: DC 2.5 V to 6 V Rated output power: 2x3W (2x4ohm) ·Frequency Band: 20Hz~30kHz ·Efficiency (Efficiency): over 90% at maximum power ·Dimensions: 21 x 18
