LM1973M/NOPB Overview
This item comes with a case that goes with it. The mounting type that is recommended is Surface Mount. The embedded file is in the 20-SOIC (0.295, 7.50mm Width) case. The device has a 3 channel. Here is a list of Volume Control functions for your reference. There is the possibility of applying the device in Consumer Audio, Professional Audio. There is a delivery within 4.5V~12V of the votage. In this device, temperature is measured in the 0°C~70°C TA range. On the chip, 20 terminations are present. If you search for the LM1973 family, you will find similar parts. Here are the device specifications: 76dB. The chip contains 20 pins. Sorting by CONSUMER CIRCUIT can be done to find out the type of consumer IC in the part. It is recommended that the minimum supply voltage (Vsup) for this part be higher than 4.5V. At +-6V volts, it can provide voltage. It reaches 12V when the maximum supply voltage (Vsup) is reached. As you can see, Surface Mount has mounted it. A 5mA-operated supply current is used. IC chips have 8 bits in total.
