An OPA197IDGKR is an instrumentation-level amplifier designed for precision measurements. It belongs to the category of linear amplifiers, which also encompass op amps and buffer amps. Being a reliable, low-power device, the OPA197IDGKR can easily be integrated into a wide range of industrial, medical, and test and measurement applications.

OPA197IDGKR’s primary function is to amplify small signals without introducing any distortions. It accomplishes this by linearizing the input signal, ensuring that the output is an exact replica of the input, just with higher amplitude. This amplification makes it possible for users to measure signals that have an amplitude too small for direct detection.

The device is available in several integrated circuit packages, such as surface-mount SOIC, TO-5, PDIP, and others, making it compatible with a wide range of applications. The amplifier is also designed with plentiful pins for use with different topologies. Each pin serves specific functions, for example, the non-inverting input pin, the inverting input pin, the output pin, and the ground pin.

OPA197IDGKR also incorporates several unique features to simplify the integration process and make the device easier to use. It has an input common-mode voltage range that extends beyond its supply rail, making it ideal for a variety of single- and dual-supply applications. It also features a high common-mode rejection ratio, wide gain-bandwidth product, and low THD+N and gain drift.

The device derives its power supply from two rails–a 0 Vground and a positive or negative supply (up to 36 V). The input is low-impedance and can easily accommodate voltages of up to 15 V without distortion. The typical supply current is 1.5 mA, and the amplifier’s high input impedance allows it to efficiently process small signals. The output voltage, when the device is powered by a +12 V supply, is typically 10Vpp for a 1VPP input signal.

OPA197IDGKR’s versatile design and high-performance capabilities make it suitable for a wide array of applications, such as precision deep-level analog tests, telemetry systems, sensor measurements, and communications systems. Its low-noise operation also makes it highly beneficial in medical imaging systems, since it is capable of producing precisely accurate readings without interference.
