STA381BW 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. Case 48-VFQFN Exposed Pad contains it. There are 2 channels on the device. The Fully Integrated Processor functions in this part are included for your reference. There is a Pre-Amplifier version of the device. There is a supply of votage within 4.5V~25.5V days of ordering. With this device, you can operate the temperature within a range of 0°C~70°C TA. 48 terminations are present on the chip. By searching for STA381 family parts, similar parts can be found. For more information, please refer to the device specs: Full Flexible Amplification. 48 pins are available on the chip. To sort IC types, use CONSUMER CIRCUIT. There should be no voltage below 4.5V on the supply line of this component (Vsup). Using this electrical component, we can represent the Sound Terminal™ series. The current supply is controlled by 60mA. The device can also be used to establish IT ALSO OPERATES AT 3.3V DIGITAL SUPPLY.
