TDA7439 Overview
There is also an accompanying case included with this set. There is a recommendation that it should be mounted with a Through Hole type mount. The file is embedded in a 30-SDIP (0.400, 10.16mm) case. This device has 2 channels. For your reference, here are some Audio Tone Processor functions. It can be used in Automotive Audio, Consumer Audio. There is a supply of votage within 7V~10.2V. 0°C~70°C TA is the temperature range for this device. A chip has 30 terminations. You can find similar parts by searching for the TDA7439 family. Chips have 30 pins that can be accessed. It is possible to sort parts based on their consumer IC type using TONE CONTROL CIRCUIT. It should not be possible to power this part with a voltage lower than 6V (Vsup). Voltage can be generated at 9V volts with this device. In this case, Through Hole mounts it. A 3 band is present on it.
