Key Featrues

Low Offset Voltage (60 µV maximum): This feature ensures minimal error in signal amplification, making the amplifier ideal for precision applications such as sensor signal conditioning and instrumentation. The low offset voltage enhances accuracy in measurements and reduces the need for calibration.
Low Input Bias Current (2 nA maximum): With minimal current drawn from the input signal, this feature minimizes loading effects on high-impedance sources, preserving signal integrity. It is particularly beneficial in applications like thermocouple and RTD measurements, where input impedance is critical.
Low Noise (8 nV/√Hz typical): The amplifier's low noise performance ensures clear signal amplification in sensitive applications such as wireless base station control circuits and optical networks. This feature enhances signal-to-noise ratio, improving overall system performance.
High CMRR and PSRR (>120 dB): The high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) ensure stable operation in noisy environments, reducing interference from power supply fluctuations and common-mode signals. This makes the amplifier suitable for industrial and automotive applications.
Wide Supply Voltage Range (±2.5V to ±15V): This feature allows the amplifier to operate in a variety of power supply configurations, making it versatile for both line-powered and portable instrumentation. It supports flexibility in design and compatibility with different system requirements.
