The OP37GSZ precision amplifier is a low-noise, high-speed integrated circuit (IC) from Analog Devices. It is manufactured in a small, space-saving SOIC-8 package that is suitable for small form factors. The amplifier offers a precision op-amp circuit with a low 80 nV noise floor and high speed of 17 V/uS. The IC has rail-to-rail output for improved dynamic range, and it features a guaranteed low total harmonic distortion of 0.003%. It is rated for a supply voltage range of 2.5 to 18 V and can operate with a single supply for VP+ and VN- up to 18 V. It is ideal for a wide range of applications, including sensor-based systems, data acquisition systems, signal conditioning, and communication systems.
