Key Featrues
Wide Supply Voltage Range (2.7 V to 36 V): The OPAx171 family operates on a broad supply voltage range, making it versatile for both low-power and high-voltage applications. This flexibility allows designers to use the same amplifier across a variety of systems, from battery-powered devices to industrial equipment, without needing multiple amplifier models.
Low Noise (14 nV/√Hz): With a low noise density of 14 nV/√Hz, the OPAx171 is ideal for precision applications such as sensor signal conditioning and audio processing. This feature ensures high signal integrity, especially in environments where minimizing noise is critical for accurate measurements or high-fidelity audio.
Rail-to-Rail Input and Output: The amplifier supports rail-to-rail input and output operation, enabling it to handle signals close to the supply rails. This capability maximizes dynamic range and is particularly beneficial in low-voltage applications, ensuring accurate signal processing even at the extremes of the supply voltage.
Low Quiescent Current (475 µA per Amplifier): The OPAx171 consumes only 475 µA per amplifier, making it highly efficient for battery-operated and power-sensitive applications. This low power consumption extends battery life and reduces heat dissipation, which is crucial for portable and embedded systems.
EMI Hardened and RFI Filtered Inputs: The OPAx171 is designed with EMI-hardened and RFI-filtered inputs, making it robust against electromagnetic interference. This feature is essential for applications in noisy environments, such as industrial automation or automotive systems, where signal integrity must be maintained despite external disturbances.

Applications
Precision Signal Conditioning for Industrial Sensors: The OPAx171 family is ideal for conditioning signals from industrial sensors such as pressure transducers, load cells, and temperature sensors. Its wide supply range (2.7 V to 36 V) and rail-to-rail input/output capabilities ensure accurate signal amplification and processing, even in harsh industrial environments. The low noise (14 nV/√Hz) and low offset drift (±0.3 µV/°C) make it suitable for high-precision applications.
Portable Medical Devices: The OPAx171 operational amplifiers are well-suited for portable medical devices, such as blood glucose meters and ECG monitors. Their low quiescent current (475 µA per amplifier) and ability to operate on low supply voltages (down to 2.7 V) make them ideal for battery-powered applications. The rail-to-rail output and high common-mode rejection (120 dB) ensure accurate signal amplification in low-power medical devices.
Automotive Sensor Interfaces: The OPAx171 series is perfect for automotive sensor interfaces, such as those used in engine control units (ECUs) or tire pressure monitoring systems (TPMS). With an operating temperature range of -40°C to +125°C and EMI-hardened inputs, these amplifiers can withstand the demanding conditions of automotive environments. The rail-to-rail input and output capabilities allow for seamless integration with various sensor types.
Energy Harvesting Systems: The OPAx171 amplifiers are ideal for energy harvesting systems, such as those used in IoT devices or wireless sensor networks. Their ability to operate on low supply voltages (2.7 V) and low quiescent current make them suitable for systems powered by small energy sources like solar cells or thermoelectric generators. The low noise and high precision ensure reliable signal amplification in energy-constrained applications.
