Key Featrues
High Slew Rate of 15V/µs - With a high slew rate, the INA159 can rapidly respond to changes in input signals, making it ideal for high-speed applications such as industrial process controls and instrumentation. This ensures minimal signal distortion and improved dynamic performance.
Wide Input Common-Mode Voltage Range - The INA159 supports input common-mode voltages extending beyond the supply rails, from -12.5V to +17.5V. This flexibility allows it to handle a wide range of signal levels, making it versatile for various industrial and audio applications.
Low Offset Voltage and Drift - Featuring a low offset voltage of ±100µV and a drift of ±1.5µV/°C, the INA159 ensures high accuracy and stability over temperature variations. This is critical for precision applications like differential-to-single-ended conversion and audio line receivers.
Single-Supply Operation Down to 1.8V - The INA159 can operate on a single supply as low as 1.8V, making it suitable for low-power and portable devices. This feature expands its use cases in battery-powered systems and energy-efficient designs.
Applications
Instrumentation Amplification: The INA159 excels in instrumentation applications, such as data acquisition systems and test equipment. Its low offset voltage and drift, combined with high slew rate and bandwidth, enable precise measurement and amplification of differential signals, ensuring accurate data collection in laboratory and field settings.
Differential-to-Single-Ended Conversion: The INA159 is well-suited for converting differential signals to single-ended outputs in audio and communication systems. Its wide input common-mode range and single-supply operation make it ideal for audio line receivers, where it can handle large signal swings while maintaining signal integrity.
Sensor Interface for Single-Supply Systems: The INA159 is ideal for interfacing with sensors in single-supply systems, such as battery-powered devices or portable instruments. Its ability to operate on low voltages (down to 1.8V) and its precision gain of 0.2 make it suitable for amplifying and translating sensor signals, such as those from pressure sensors or accelerometers, for further processing by ADCs.
