LM4873LQX Product Details

LM4873LQX Overview


There is a device embedded in 24-WFQFN Exposed Pad .Amp parts is recommended that the chip be packaged in a Tape & Reel (TR) case.Amp parts is possible to terminate a transmission line wAmp partsh a device matching Amp partss characteristic impedance, referred to as a 24 termination.2-Channel (Stereo) with Stereo Headphones is the output configured for it.The device is of type Class AB .The 24 pins are pronged contacts which are part of a signal interface in a computer or other communication device.Electronic parts are mounted in the way of Surface Mount .Amp parts is powered by a voltage of 2V~5.5V volts.2 channels are present on the device.Operation can be ensured by Depop, Input Multiplexer, Shutdown, Thermal Protection .A temperature greater than -40°C~85°C TA should not be used.This is a member of the LM4873 family.The electronic part is mounted in the way of Surface Mount .As a result of the limAmp partsations of this electronic part, Amp parts has a maximum output power of 3W kWh per hour.To ensure normal operation, the supply voltage (Vsup) must be maintained above 2V .The maximum supply voltage (Vsup) is reached at 5.5V .The device is powered by a voltage of 5V volts.This is a member of the Boomer® series.7.5mA external influences affect the amount of quiescent current consumed by this device.A maximum supply current of 15mA is achieved.
