LM1972M Overview
In addition, the book comes with a case study as well. It is recommended that you mount it in a Surface Mount mounting type. 20-SOIC (0.295, 7.50mm Width) case embeds it. It has 2 channels. Here is a list of Volume Control functions for your reference. Consumer Audio, Professional Audio can be used with the device. There is a delivery within 4.5V~12V of the votage. 0°C~70°C TA is the temperature range for this device. A chip has 20 terminations. Search for the LM1972 family to find similar parts. Refer to the device's specifications: 78dB. The chip has 20 pins that are accessible from the outside. Sorting by CONSUMER CIRCUIT can be done to find out the type of consumer IC in the part. There should be no voltage below 4.5V on the supply line of this component (Vsup). This part of the family is called the Audio Control ICs family. The voltage it can produce is +-6V volts. The chip conducts when it is supplied with 12V-voltage. 16 is the number of bits on an IC chip.
