Key Featrues

Low Input Offset Voltage (150 µV maximum): This feature ensures minimal error in signal amplification, making the OP400S ideal for precision applications such as sensor signal conditioning and medical instrumentation, where accuracy is critical.
Low Offset Voltage Drift (1.2 µV/°C): The low drift over a wide temperature range (−55°C to +125°C) guarantees stable performance in extreme environments, enhancing reliability in aerospace and industrial applications.
High Open-Loop Gain (5000 V/mV minimum): This high gain allows for superior signal amplification with minimal distortion, improving performance in high-gain and low-noise applications like audio processing and data acquisition systems.
On-Chip Zener Zap Trimming: This eliminates the need for external offset nulling, simplifying circuit design and reducing component count, which is beneficial for compact and cost-effective designs in consumer electronics and portable devices.
Excellent CMR (120 dB) and PSRR (1.8 µV/V): These features ensure high immunity to common-mode noise and power supply variations, making the OP400S suitable for use in noisy environments such as automotive and industrial control systems.
