TEA6320T/V1,518 Overview
There is also an accompanying case included with this set. There is a recommendation that it should be mounted with a Surface Mount type mount. A 32-SOIC (0.295, 7.50mm Width) case has been embedded in it. This device has 2 channels. For your reference, here are some Volume Control functions. It can be used in Pre-Amplifier. There is a supply of votage within 7.5V~9.5V. -40°C~85°C TA is the temperature range for this device. A chip has 32 terminations. You can find similar parts by searching for the TEA6320 family. Refer to the following specifications for the device: 110dB, 20dB. It is possible to sort parts based on their consumer IC type using SOUND FADER CONTROL CIRCUIT. It should not be possible to power this part with a voltage lower than 7.5V (Vsup). A maximum supply voltage (Vsup) is reached at 9.5V. A 2 band is present on it. 33mA controls the supply current.
