Working Principle of DEM-OPA-SSOP-3A

The working principle of the DEM-OPA-SSOP-3A evaluation board is based on its adaptive biasing technique. The primary components of this technique are a Current Mirrors Distribution (CMD) and a Matrix Bias Generator (MBG).

The CMD is a four-way modular circuit that divides current into four separate branches. This ensures that all op-amp channels receive equal and constant current with high accuracy. The MBG is an electronic device that acts as a reference source for the op-amp and provides the critical bias required for proper operation.

The CMD and MBG work together to provide precise current control in the op-amp circuit. This helps reduce harmonic distortion and ensures that all op-amp channels operate in linear mode. Therefore, the DEM-OPA-SSOP-3A is able to offer a wide bandwidth and gains up to 520 times which enable it to suit a variety of applications.
