Working Principle

The LTC6420IUDC-20#TRPBF is a high-performance, low-noise linear amplifier with a wide frequency range. It operates by amplifying the input signal with a very low noise operational amplifier (Op Amp) at each stage. This enables the device to have extremely low noise, wide bandwidth, and excellent gain stability over a wide temperature range.

The device has a differential input configuration and an open-loop gain of up to 100 V/V. The gain of the amplifier is determined by the feedback resistor Rf which is connected between the inverting and non-inverting inputs. The gain of the device can be changed by varying the feedback resistor.

The device features a low power input stage, with a low input bias current of only 1 μA per stage. The LTC6420IUDC-20#TRPBF also has a high common-mode rejection ratio (CMRR), with a typical value of 65 dB. This feature enables the device to reject any common-mode signal, such as noise or stray signals that are present in the input signal.

The device also has a very high output swing, up to 6V peak-to- peak, and can be operated from a single +5 V power supply. The output stage of the device is protected from any over-current or over-temperature conditions, which makes the device safe for use in demanding applications.

Conclusion

The LTC6420IUDC-20#TRPBF is a special purpose, high-performance linear amplifier designed for highly sensitive applications. Its wide frequency range, low noise, and high dynamic range makes it an excellent choice for precision signal measurement, audio and military applications. Its low power, high CMRR and excellent gain stability make it suitable for a wide variety of demanding applications. This device is an excellent choice for applications that require exceptional performance and precision.
