INA4180A4IPWR is a high-performance instrumentation amplifier, which is especially suitable for applications requiring flexible gain adjustment (via iterative resistor design) and precision accuracy in the industrial world, such as industrial process control, data acquisition, and telecommunications. It combines high gain accuracy, low power consumption and excellent linearity to ensure consistent and reliable electrical characteristics.

The INA4180A4IPWR features a unique design that makes it possible to operate with a very low power consumption, while providing excellent linear performance. The amplifier consists of two differential amplifiers connected in a feedback configuration. The first differential amplifier consists of a cascode VAS and two class-A current mirrors. The second differential amplifier consists of two Class-A current mirrors. The current mirrors are designed to provide a constant and stable gain over a wide dynamic range. The output of both differential amplifiers is then combined in the feedback loop. The signal is then amplified and filtered through the output transformer.

The signal output can be configured with a resistor from a Gain Adjustment Pin to a negative power supply voltage. The gain adjustment control also allows the signal to be attenuated in the output stage, which allows the output signal level to be varied in order to provide optimal response. The amplifier also features an integrated ESD protection circuit, which ensures robust protection against high voltage transients.

The INA4180A4IPWR is capable of delivering up to 10 watts of power in different configurations. This makes it an ideal solution for high power applications, such as industrial process control, industrial robotics, and instrumentation applications. The amplifier also features a wide output voltage range, which enables it to operate in both low and high power applications.

The INA4180A4IPWR is designed with advanced reliability and robustness to ensure long life and high accuracy. The device is tested to higher common mode rejection ratio and low input offset voltages. Moreover, the power dissipated in the output stage is much lower than those in other instrumentation amplifiers, making it very suitable for high power applications. All these features make the INA4180A4IPWR an ideal choice for precision accuracy and application flexibility in the aerospace, industrial, electronic and medical industries.
