Overview

The OP27GPZ is a high-precision, low-noise operational amplifier designed for applications requiring exceptional signal integrity. It features a very low input offset voltage of 30 uV and a low noise floor of 4.5 nV/rtHz, making it ideal for accurate instrumentation and low-level signal amplification. The 8-PDIP through-hole package is well-suited for prototyping and easy integration into legacy industrial systems.

Why Choose This Part

The OP27GPZ offers a superior balance of 8 MHz gain bandwidth and a 2.8V/us slew rate while maintaining a low input bias current of 15 nA. Its robust design allows for operation across a wide temperature range of -40degC to 85degC, ensuring reliability in demanding environments.

Applications

Precision Instrumentation
Utilized in weigh scales and strain gauge amplifiers where low offset and high stability are critical.
Thermocouple Amplifiers
Ideal for amplifying millivolt-level signals from temperature sensors with minimal error.
Low-Noise Audio Preamplifiers
Used in high-fidelity audio paths where maintaining a high signal-to-noise ratio is necessary.
Data Acquisition Systems
Serves as a high-accuracy front-end buffer for 12-bit and 16-bit analog-to-digital converters.

Getting Started

To evaluate the OP27GPZ, it can be directly inserted into a standard breadboard or an 8-pin DIP socket for rapid circuit validation. Engineers should use high-quality decoupling capacitors (0.1 uF ceramic) close to the supply pins to maintain the device low-noise performance and stability.
