THS4225DR

The THS4225DR is a Low Voltage, dual channel instrumentation amplifier used in various applications. The THS4225DR is designed to optimize gain accuracy over temperature, voltage and time. It features low gain error, extended temperature range and a wide range of input bias currents for a wide range of applications. This makes the THS4225DR suitable for applications such as instrumentation, data acquisition, sensor measurement and medical equipment.

The THS4225DR is composed of a low-gain error precision voltage follower, an output buffer and two instrumentation amplifiers in a single package. The Voltage Follower is a high-performance current-feedback amplifier with a gain saturation of <1%. Its gain block is optimized to enhance the precision and DC accuracy of the amplifier. Its low-noise internal compensation resistor reduces device to device gains variations making gain errors extremely low.

The Output Buffer ensures the performance of the amplifier is not degraded due to capacitive and resistive loading on the output. The buffer also alleviates any instability that can arise by adding a load to the output. The buffering is enabled using an internal current mirror, which is optimized to reduce cross-over distortion.

The Instrumentation Amps are designed to provide good CMRR making them ideal for accurate measurements and sensing of various signals. The amplifiers offer a wide common-mode voltage range and rail-to-rail input range that allows them to better provide accurate gain across a wide range of signal levels. The amplifiers are also able to reject common-mode signals, so it is suitable for use in noise-sensitive environments.

The THS4225DR is designed to provide excellent low-distortion and low-noise performance. The amplifier features a low-noise buffer enabling signal fidelity with an input voltage range of up to ±6V. The THS4225DR also features a high-accuracy gain setting resistor, enabling accurate gain settings and ensuring gain accuracy across temperature, voltage and time.

In summary, the THS4225DR is an ideal instrumentation amplifier for applications such as data acquisition, sensor measurement and medical equipment that require low-noise and precision. It features low gain error, extended temperature range and a wide range of input bias currents.
