Workimg Principle

The THS4501CDR amplifier is designed to amplify and buffer signals in instrumentation and communication applications. It utilizes an input stage optimized for unity gain bandwidth, followed by a closed loop gain stage and an output buffer. This design provides an amplifier with very low noise and distortion, as well as very high-common-mode and power supply rejection.

The amplifier can be used for both single-ended or differential signals. It provides a high-speed performance with a guaranteed -3dB bandwidth of 1.6GHz and a high-gain bandwidth (GBW) of 4.1GHz. The THS4501CDR amplifier is powered from a single +5V to +15V supply and can output signals up to ±5V.

The THS4501CDR amplifier is also designed with a high-impedance input and low-impedance output to ensure a good signal-to-noise ratio and reduce cable capacitance effects due to its high-impedance inputs. The amplifier also features a very low input bias current that does not degrade the performance of the amplifier, even for long cable runs.

The THS4501CDR is designed to provide an optimized gain accuracy of 0.02% over temperature and excellent total harmonic distortion (THD) of 0.02%. Its high-speed performance and excellent common-mode rejection makes it ideal for a range of precision linear amplifier, instrumentation, buffering and signal conditioning applications.
