TDA7721 Overview
With the book, you will also receive a case study. In terms of mounting type, the recommended type is Surface Mount. In this case, it is embedded in the 28-TSSOP (0.173, 4.40mm Width) case. This device has a 6 channel configuration. To assist you, this part includes Audio Signal Processor functions. It is possible to apply the device in the Automotive Audio axis. Votage will be supplied within the period of 4.5V~13V. In terms of temperature, this device works within a range of -40°C~85°C TA. If you search for the TDA7721 family of parts, you will be able to find similar parts. I would like you to refer to the related specifications of the device: 100dB. Sorting by TONE CONTROL CIRCUIT can be done based on what type of consumer IC the part contains.
