Controllable Gain Transimpedance Amplifier

Home / Controllable Gain Transimpedance Amplifier

Programmable gain TIAs (PGTIAs) can utilize a single amplifier to handle the wide dynamic ranges encountered in applications such as high-sensitivity optical systems, precision analytical instrumentation, and electrochemical and bioelectrical signal detection. Precision instrumentation systems that measure physical properties using a photodiode or other current-output sensor often include a transimpedance amplifier (TIA) and a programmable-gain stage to maximize dynamic range. The device offers a combination of low input bias current, DC precision performance, low noise, high. However, their performance is often hampered by saturation issues due to high input currents, leading to prolonged recovery times.
