IdealPhotonics' voltage amplifier is a module used to amplify small voltage signals output from photodetectors. It uses multi-stage amplification circuits (such as differential input and programmable gain) to increase the signal amplitude to suit subsequent ADC or processing circuits. Its input noise is <μV, and the gain range is 60-100dB. It is suitable for low-speed, high-precision applications such as photodiode signal conditioning, but electromagnetic shielding is necessary to avoid interference.High-precision voltage amplification (μV-level resolution), but a trade-off between bandwidth and noise must be considered in the design.
