TPA3116 CSR4.0 Bluetooth Amplifier Module support APTX
Content：
TPA3116 CSR4.0 Bluetooth Amplifier Module support APTX use CSR 8645 chip
SL-BD18-A the new design of digital power amplifier with bluetooth, it is new product for using TPA3116, and connection is very simple. It is a 50W continuous average per channel and use CSR8645 bluetooth, power efficiency and good sound.
2.Power supply filter capacitor using Nikon and Panasonic electrolytic capacitors
3.Signal main circuit electrolytic capacitor Taiwan brand names, the main filter capacitor used in Japan Nikon electrolytic capacitors, to ensure strong support for a steady stream of power.
4.Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
5.1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.
6.Using the latest Bluetooth version 4.0
7.Connectivity Bluetooth connection methods and general equipment like!
8.Input only Bluetooth input.
