The OP77HP is a high-performance, precision operational amplifier from Analog Devices Inc. This op-amp is designed to offer an optimal balance between low offset voltage and drift, high input impedance, and fast settling time. It is an excellent choice for applications requiring high accuracy and stability over time and temperature, such as instrumentation, data acquisition systems, and precision filters.

With a very low offset voltage of less than 75 µV and an extremely low drift of less than 1.3 µV/°C, the OP77HP sets a new standard for precision op-amps. These characteristics significantly reduce the need for external calibration, saving both time and cost in precision applications. The high input impedance minimizes the loading effect on the input signal, preserving signal integrity and ensuring accurate amplification.

The OP77HP also features a fast settling time, making it suitable for high-speed analog-to-digital converters (ADCs) where quick and precise settling is crucial. This makes it an ideal choice for applications that require both high precision and high speed, such as medical devices, test equipment, and control systems.

This operational amplifier operates within a supply voltage range of ±3 V to ±18 V, providing flexibility in various circuit configurations and ensuring compatibility with a wide range of supply voltages. Additionally, the OP77HP boasts a low noise performance with a noise figure of only 3 nV/√Hz at 1 kHz, which is beneficial for low-noise amplification in sensitive applications.

The OP77HP is available in a variety of packages, including the standard 8-lead PDIP, 8-lead SOIC, and 8-lead CERDIP, allowing for easy integration into different types of circuit boards and design layouts. With its combination of precision, speed, and versatility, the OP77HP from Analog Devices Inc. is a reliable and efficient solution for demanding applications that require the utmost in operational amplifier performance.
