LM1973M/NOPB Overview
With the book, you will also receive a case study. The mounting type that is recommended is Surface Mount. I have embedded a 20-SOIC (0.295, 7.50mm Width) case with it in order to protect it. There are 3 channels on the device. The Volume Control functions in this part are included for your reference. The device can be applied in Consumer Audio, Professional Audio. There is a supply of votage within 4.5V~12V. In this device, temperature is measured in the 0°C~70°C TA range. The chip has 20 terminations. By searching for LM1973 family parts, similar parts can be found. I would like you to refer to the related specifications of the device: 76dB. Chips have 20 pins that can be accessed. Sorting by CONSUMER CIRCUIT can be done to find out the type of consumer IC in the part. This part should have a minimum supply voltage of 4.5V (Vsup). There is a part of Audio Control ICs family. It can produce voltage at a voltage level of +-6V volts. When Vsup reaches 12V, the maximum supply voltage (Vsup) is reached. As seen in the picture, Surface Mount is mounting it. A 5mA-operated supply current is used. The total number of IC chips is 8.
