The INA141U/2K5G4 is a precision instrumentation amplifier designed for use in demanding medical, industrial and scientific applications. With excellent accuracy and power supply rejection, the INA141U/2K5G4 provides excellent performance while minimizing system power consumption. The INA141U/2K5G4 has a low offset voltage which is less than 1µV and provides superior linearity when compared to other op amps. It has very low quiescent current which is only 1.02mA and operates from a single voltage supply, typically 5V to 15V.

The INA141U/2K5G4 has a wide operating temperature range of -40°C to 85°C, is offered in 8-pin or 14-pin packages and is available in single, dual or quad configurations. The INA141U/2K5G4 can be used for applications such as signal conditioning, data acquisition systems, medical instrumentation, industrial and scientific measurements, and other applications requiring low power, precision amplification.

The INA141U/2K5G4 has two operational amplifier (op amp) stages: a non-inverting amplifier and an inverting amplifier, which are connected in series to form the instrumentation amplifier. The non-inverting stage is connected to the input signal and acts as a preamplifier. The second stage, the inverting amplifier, is connected to the output of the non-inverting stage and provides gain. This two-stage amplifier is designed to reduce circuit noise and improve signal-to-noise ratio.

The INA141U/2K5G4 has three external resistors that are connected in a feedback loop to set the gain of the amplifier. The resistors control the non-inverting input impedance and the output resistance. These resistors also help to minimize noise and frequency response errors and can be adjusted to match the application.

The INA141U/2K5G4 is designed to minimize common-mode voltage errors. This feature is achieved through the use of a balanced, equalized input stage, which helps to minimize the effect of variations in the power supply voltage on the output signal. Additionally, the amplifier has a low input bias current allowing it to work at low up to high-voltage levels. This feature, coupled with the low offset voltage, makes the INA141U/2K5G4 ideal for applications where accuracy and stability are of paramount importance.

The INA141U/2K5G4 is a low power, high performance, instrumentation amplifier that is ideal for applications requiring accurate signal amplification. With its low quiescent current and wide operating temperature range, the INA141U/2K5G4 is a reliable and versatile amplifier that can be used in a wide range of applications. It is well suited for use in medical instrumentation, data acquisition systems and any other demanding industrial or scientific applications.
