Instrumentation, OP Amps, Buffer Amps are all areas of linear amplifiers. This article will discuss the application field and working principle of INA2180A2IDGKT.

The INA2180A2IDGKT is an integrated circuit (IC) for those requiring noise immunity, precision, and low power consumption. It is a low-cost, low-power, chopper-stabilized, very low offset voltage, dual, instrumentation amplifier. As a result, it is widely applied in many situations such as medical, industrial, and consumer electronics.

The IC contains two low-noise amplifiers and a rail-to-rail output stage. The amplifier is designed to prevent thermal errors and input related noise, by using chopper-stabilized architecture. The device has an analog supply current of 8uA and a digital supply current of 150uA.

Although the INA2180A2IDGKT is designed to be extremely low-power, it still has some noise immunity. Specifically, it has a high common-mode rejection ratio (CMRR) of 115dB, and a low-noise, wide-band-width design. The CMRR allows the amplifier to reject noise from the power supply, thermal drift, and EMI.

The working principle of the INA2180A2IDGKT is based on the chopper-stabilized approach. This approach works by converting an analog input signal into a high-frequency, pulse-width modulated (PWM) signal, which is then processed in order to reduce offset voltages and thermal drift. The PWM signal is then converted back into an analog output.

This chopper-stabilized approach makes the INA2180A2IDGKT a very reliable and cost-effective solution for precision applications. The amplifier has a wide frequency range, allowing it to be used in many different applications. Additionally, it has a low noise floor, making it well-suited for applications requiring low-noise performance.

In summary, the INA2180A2IDGKT is an excellent choice for those needing a low-cost, low-power, and noise immunity linear amplifier with precision and low power consumption. The device works by converting an analog input signal into a high-frequency PWM signal and then converting it back into an analog output. Additionally, it has a wide frequency range and a low noise floor. This makes it well-suited for precision applications requiring low-noise performance.
