LM4839LQ/NOPB Product Details

LM4839LQ/NOPB Overview


I have embedded this device in 28-WFQFN Exposed Pad .The chip is recommended to be packaged in Tape & Reel (TR) case. In 28 terminations, a transmission line is terminated with a device that matches its characteristic impedance.Output 2-Channel (Stereo) with Stereo Headphones is configured for this device.An electrical device of type Class AB is involved.In a computer or other communication device, there are two pronged contacts called 28 pins.Amp parts is mounted in front of Surface Mount .In this electrical device, the supply voltage is 2.7V~5.5V .There are 2 channels available on the device.Ensure that Bass Boost, Depop, Input Multiplexer, Mute, Shutdown, Thermal Protection, Volume Control is maintained when operating.Amp parts is recommended that the operating temperature do not exceed -40°C~85°C TA °C.The device is equipped with a total of 28 pins.The LM4839 family includes it.There is an electronic part in the way of Surface Mount .In this electronic part, the output power is a maximum of 2.2W kWh per hour.As a general rule, the supply voltage (Vsup) should be maintained above 2.7V .During this time, the maximum supply voltage (Vsup) reaches 5.5V .This device runs on a power supply of 5V volts.Boomer® is the series number for this electronic part.In the case of 30mA , the maximum supply current is available.1 bands describe the energy levels at which electrons may reside.
