xpt6871 is a ab kind, bridge type audio power amplifier. 5 v working voltage, maximum driving power for: 4 w (3 ω load thd < 10%), 3 w (4 ω load, thd < 10%); audio range total harmonicdistortion noise is less than 1% (20 hz-20 khz); xpt6871 application circuit is simple, just a few peripheral device; xpt6871 output don’t need external coupled electric lift on maybe thecapacitance, buffer network, the feedback resistance.
xpt6871 the sop encapsulation, particularly suitable for small volume, small weight portable system. xpt6871 can throughthe control into sleep mode, so as to reduce power consumption; xpt6871 interior has automatic shutoff overheating protection mechanism. xpt6871 stable work, as high as 2.5 mhz bandwidth gaindeposition, and units gain stable. through the configuration peripheral resistance can adjust the amplifier’s voltage gain, convenient application. the market is a proof of the high quality and highreputation of the classic chip.
