Unisonic Technologies PA4867
PA4867 is a stereo audio power amplifier capable of delivering typically 2.1W to a 4Ω load or 2.4W to a 3Ω load each channel with less than 1.0% THD+N using a 5V power supply. The UTC PA4867 has integrated depop circuitry that virtually eliminates transients that cause noise in the speakers during power up and when using the shutdown modes. UTC PA4867 has a new circuit topolopy which can eliminate headphone output coupling capacitors.| Part No. | PA4867 |
