SSM2141 chip +5534 op amp output scheme

Input balanced signal and output unbalanced signal. It is suitable for system modification where the former stage is balanced signal output and the latter stage has no balanced signal input.

Generally, the professional front stage will have a balanced output. If there is no balanced input function on the rear stage, it can be installed as a small board. This board can convert your balanced signal source to the unbalanced signal required by the ordinary power amplifier and then connect it to the power amplifier board. To achieve balanced input

We use professional-grade SSM2141 for the balanced input chip. The internal resistance of SSM2141 is laser trimmed, and its accuracy is as high as 0.0001%. In terms of distortion, noise and parasitic interference, its performance can reach the level of "professional". Compared with the general use of op amps, the performance of the conversion circuit is greatly improved.

By adjusting the resistance on the SSM2141 chip, excellent common-mode noise suppression and offset error performance can be achieved, ensuring that the device has high gain accuracy and can simulate the performance of a fully balanced transformer solution for line drive.

At the same time as the board is designed with a balanced input interface, an RCA head input is added, and any input mode is selected through the switch on the board, so that the two functions of balanced input and RCA input are realized on the rear stage, and the modified power amplifier is modified. Time is more convenient.
