The LTC2055HMS8#PBF is a high-performance, zero-drift operational amplifier from Linear Technology, designed for precision applications that require low offset voltage and drift over time and temperature. This op-amp is part of Linear Technology's family of auto-zeroing amplifiers that use a proprietary circuit to continuously correct for DC offset, resulting in a significant reduction of offset errors and 1/f noise.

Key Features

• Zero-Drift Topology: Provides continuous self-calibration which results in a very low input offset voltage of 2.5µV and an ultra-low offset drift of 0.03µV/°C, ensuring high accuracy over a wide temperature range.
• Low Noise: Offers an impressive low noise density of 1.2µVP-P (0.1Hz to 10Hz) which makes it ideal for sensitive applications like medical instrumentation and precision sensors.
• Wide Supply Range: Operates from a single 2.7V to 5.5V supply or dual ±2.7V to ±5.5V supplies, providing design flexibility for various power environments.
• Rail-to-Rail Output: The rail-to-rail output stage ensures maximum dynamic range, which is especially beneficial in single-supply operations and for driving analog-to-digital converters (ADCs).
• Robust Design: The LTC2055HMS8#PBF is specified over the industrial temperature range (-40°C to 85°C) and can operate up to 125°C, making it suitable for harsh environments.
• Package: Available in an 8-lead MSOP package, it is compact and suitable for space-constrained applications.
