Device Overview

The THS4120CDGKR is a single-supply operational amplifier that is designed to provide excellent gain and power consumption in precision applications. The device has an on-chip level-shift network that allows the device to be used with virtually any output signal swings, from rail-to-rail, to ground-referenced. The device also features a true offset voltage of less than 2.0 mV, which allows for extremely precise offset control.

The THS4120CDGKR has an adjustable DC gain of > 70 dB, a low input offset voltage of 2 mV, a high slew rate of 10V/µs and a low supply current of 20 µA. The device also features a wide input common-mode voltage range of 6 to 20 V, enabling it to be used with signal swings from ground-referenced to rail-to-rail. The low noise of 0.01 µV RMS makes this device ideal for low-noise amplifiers and high precision applications.

Working Principle

The THS4120CDGKR consists of two main parts, an input stage and an output stage. The input stage provides for differential gain and noise control. This stage consists of an input differential pair, an adjustable-gain differential amplifier, and an output deviation compensation. The output stage has a true offset voltage of less than 2 mV and allows for precise offset control. It also has a gain of > 70 dB, a slew rate of 10V/µs, and a low supply current of 20 µA.

The input stage of the device provides differential gain and noise control. The differential amplifier has an adjustable gain that is set externally by applying a voltage to a dedicated input pin. In addition, the input stage has a distortion compensation network that helps reduce distortion and harmonic distortion. The output stage has a true offset voltage of less than 2 mV and allows for precise offset control.

The THS4120CDGKR is designed to provide precision performance with low noise and low power consumption. It is ideal for applications such as instrumentation amplifiers, linear amplifiers, op-amps, and buffer amplifiers. The device features wide input common-mode voltage range, high DC gain, and low offset voltage drift. The device also features low supply current and low noise, making it perfect for use in low-noise, low-power amplifier applications.
