Home / Transimpedance Amplifier Power Consumption
Power Consumption: TIAs should have low power consumption, which is proportional to the amplifier's quiescent current in the unloaded state. Low values of quiescent current are preferred so that the device will not leak excessive power. Transimpedance amplifiers (TIAs) act as front-end amplifiers for optical sensors such as photodiodes, converting the sensor's output current to a voltage.
