The LTC2051HMS8 is a high-performance, dual zero-drift operational amplifier from Linear Technology, designed to provide precision and stability in a variety of applications. This op-amp is part of Linear Technology's family of auto-zeroing amplifiers which use a proprietary technique to continuously self-calibrate for DC offset, resulting in minimal input offset voltage and offset drift over time and temperature.

Key Features

• Zero-Drift Topology: Ensures an ultra-low input offset voltage of 5µV max and a maximum offset drift of 0.05µV/°C, making it ideal for high-accuracy applications.
• Low Noise: Offers a low 1/f noise characteristic, with a typical noise density of 1.5µVP-P from 0.1Hz to 10Hz, ensuring signal fidelity in noise-sensitive circuits.
• High Gain Bandwidth Product: Features a 3.5MHz gain bandwidth product and a fast slew rate of 2V/µs, providing good dynamic response.
• Power Efficiency: Operates with a supply voltage range from 2.7V to 5.5V and has a low supply current of 750µA per amplifier, making it suitable for battery-powered devices.
• Extended Temperature Range: The H-grade version is tested and guaranteed to specifications from -40°C to 125°C, accommodating a wide range of environmental conditions.
• Rail-to-Rail Output: The rail-to-rail output stage allows the output to swing within millivolts of the supply rails, maximizing dynamic range in low-voltage applications.
• Robust Package: Comes in an 8-lead MSOP package that is compact and suitable for space-constrained applications.
