BU7831KN-E2 Product Details

BU7831KN-E2 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. The file is embedded in a 20-VFQFN case. This device has 6 channels. For your reference, here are some Fully Integrated Processor functions. It can be used in Consumer Audio. There is a supply of votage within 2.5V~3.3V. -30°C~85°C TA is the temperature range for this device. A chip has 20 terminations. You can find similar parts by searching for the BU7831 family. Chips have 20 pins that can be accessed. It is possible to sort parts based on their consumer IC type using CONSUMER CIRCUIT. It should not be possible to power this part with a voltage lower than 2.5V (Vsup). There is a Other Consumer ICs family. Voltage can be generated at 3V volts with this device. A maximum supply voltage (Vsup) is reached at 3.3V. In this case, Surface Mount mounts it. 3.7mA controls the supply current.

BU7831KN-E2 Features


With 20-VFQFN channels
operate temperature at the range of -30°C~85°C TA
