LM4549BVH OverviewSpace-saving reasons have led to it being packaged in a 48-LQFP package. Tray is the packaging method used. Because it is a type of Audio, AC '97, it delivers high-efficiency performance in many applications. It uses a mounting type of Surface Mount. A -40°C~85°C operating performance setting allows it to operate normally. It is equipped with a total of 2 / 2 ADCs and DACs. Supply voltage 4.2V~5.5V is provided to the analog circuit. It is supplied with a voltage of 3.3V~5.5V to power the digital circuit. Signals are prevented from reflecting off the transmission line's terminations by using 48 terminations. 48-pin electronic devices are what it is. The board has 48 pins configured. Find more related parts by using its base part number LM4549. Mounted on a PCB based on the technology of Surface Mount. Supply voltage should be maintained at 5.5V. It is recommended that the minimum supply voltage be kept at 3V. The power supply for this device is 3.35V. In order to convert digital signals into analog signals, there are 2 D/A converters.
