Working Principle

The TLE2021ACDRG4 is an operational amplifier that operates on the principle of applying an input signal to two high gain amplifiers or channels and then combining their outputs. The two channels are typically configured in a differential arrangement and have bipolar input stages. The input signal is then passed through low noise, low distortion differential voltage amplifiers (consisting of the input stage and output stage).

The output stage is responsible for providing the output voltage gain of the amplifier. The differential amplifier allows the inputs to be connected to the same reference potential. This eliminates the need for level shifting of the input signal. The differential architecture also improves the performance of the amplifier as there is no need for a compensation capacitor.

The TLE2021ACDRG4 can operate over a wide range of supply voltages and currents. It is rated for maximum operating power of ± 5 V and can be used with analog and digital signal sources. It provides an excellent CMRR and an adjustable gain range of 0.45 dB to 219 dB.The amplifier can also compensate for offset errors and provide temperature stability.
