The LT1413S8#PBF is a CMOS linear amplifier and can operate from a single power supply. It has an output voltage range of 0 V to 3 V.

Working Principle

The LT1413S8#PBF amplifier is based on the transimpedance amplifying principle. It converts a differential input signal into a proportional voltage output. This conversion is done by using the high-speed transimpedance amplifying technique. The amplifier uses two signal processing elements for signal conversion. First, two differential gain resistors convert the signal from differential to single ended voltage. Then a high speed, low powered feedback amplifier converts the signal from voltage to current. This current is then amplified and filtered with a high-speed operational amplifier; the output current from this amplifier is finally converted back to a voltage signal.

The operational amplifier provides the active elements in the amplifier circuit. It is used to amplify the input signal for further processing. The circuit utilizes a PI filter to remove any distortion and noise that may be introduced by the amplifier\'s active components. The output stage is a high-speed buffer amplifier circuit that is designed to provide a low-level output signal.

The LT1413S8#PBF operates efficiently and provides high-speed performance. It is designed to reduce unwanted noise and distortion caused by input signals and to provide very low PWMR and THD levels. It has a supply current rating as low as 0.5 mA in normal operation and up to 25 mA during power up. Its power-down modes help conserve power and reduce power consumption during idle periods. It also has an open loop voltage gain of typically 10 V/V.
