The OPA2373AIDGST is a high-performance, low-noise, and high-speed instrumentation amplifier with precision bipolar technology. It features a wide supply range, high input impedance, high precision gain accuracy, low noise, and fast settling time. It includes a low-pass filter to reduce the influence of high frequency noise and has an auto-zero circuit which eliminates added distortion and improves signal-to-noise ratio. This makes it suitable for performing signal conditioning in medical sensor applications, such as electrocardiogram (ECG) signal analysis.

The OPA2373AIDGST instrumentation amplifier provides high precision amplification of input signals that require the best signal-to-noise ratio and high accuracy. Its wide supply range of 4 V to 36 V and wide bandwidth of 1 MHz make it suitable for systems that require fast settling times. Its high input impedance of 1.40 MΩ allows it to amplify signals with high gain and low noise. Additionally, its low current draw of 3 mA, low cost, and dual differential inputs provide excellent cost effectiveness and reliability.

The OPA2373AIDGST instrumentation amplifier has an open-loop gain of 120 dB and a high common-mode rejection ratio (CMRR) of 120 dB. Its wide bandwidth and low output-referred noise of 7.8 μV make it ideal for high-precision signal conditioning in medical test applications. Additionally, its high input impedance and high precision gain accuracy make it suitable for use in low-noise preamplifiers and other signal conditioning applications.

The OPA2373AIDGST instrumentation amplifier works by amplifying an input signal without changing its frequency or phase responses. It uses a differential input stage and an open-loop unity-gain buffer stage. The input stage amplifies the signal before it is sent to the unity-gain buffer stage. The output of this stage is then passed through the low-pass filter and auto-zero circuitry, which reduces the distortion and noise before the signal is sent out of the amplifier.

The OPA2373AIDGST instrumentation amplifier is well suited for applications such as medical test equipment, low-noise preamplifiers, and other instruments used in medical labs and hospitals. Its wide bandwidth, high precision gain accuracy, and low cost make it an ideal choice for signal conditioning in medical test applications. Additionally, its wide supply range, low output-referred noise, and fast settling times make it suitable for use in systems that require quick and accurate responses.
