Item description
This is a listing of two PCBs of a very low distortion preamplifier ( Gain = 2) that can convert an unbalanced signal to a balanced signal.
The circuit make uses of a famous balanced line receiver DRV134. The chip can offer a distortion as low as 0.0005% at 1KHz and 0.001% in the whole audio frequency band( below 18KHz) when driving 600ohm load ! Maximum swing can be 18Vrms at 0.01% distortion ! The gain is fixed at 6dB ( 2 times).
Supply voltage : +/-15v to +/-18V.
The PCBs have a board thickness of 1.6mm, and copper thickness of 70um. This is four times normal board copper thickness ! The surface is gold plated and coated with two-sided solder resist for maximum durability.
PCB dimension : 52mm x 52mm
Each board consists of 2 DRV134 and 4 10uF 35V e-cap and 4 0.1uF 50v film cap for decoupling purpose. As the circuit is too simple we do not provide schematic. But as the rest of the products we provide email technical support !
This listing is for two boards.
We do air shipping worldwide at US$6.00. We welcome combine shipping.
