TPA321D Product Details

TPA321D Overview


In 8-SOIC (0.154, 3.90mm Width) is embedded this device.Chips should be packaged in Tube cases.Transmission lines can be terminated with 8 terminations, which have devices that match the line's characteristic impedance.1-Channel (Mono) is used for its output.In this case, it is an electrical device of type Class AB .8 pins are pronged contacts on a computer or other communication device that form a signal interface.The electronic part is positioned in the way of Surface Mount .This electrical device has a 2.5V~5.5V supply voltage.Currently, the device has only 1 channels.Amp parts is possible to operate wAmp partsh Differential Inputs, Short-Circuit and Thermal Protection, Shutdown .No temperature higher than -40°C~85°C TA should be used for operations.This device has 8 pins.Amp parts is part of the TPA321 family.As of this moment, the maximum Output Power of this electronic part is 700mW kWh per hour.Amp parts is important to keep the supply voltage (Vsup) above 2.5V so that the device functions normally.Vsup reaches 5.5V at the maximum.In this electronic part, the supply type is Single .As long as external factors do not affect it, it consumes 700μA of quiescent current.
