TI OPA2197IDR Dual Operational Amplifier 2 Circuit Rail-to-Rail
The OPA2197IDR is a dual-channel, high-precision operational amplifier (op-amp) designed by Texas Instruments (TI) for demanding analog signal processing applications. Featuring a rail-to-rail input and output (RRIO) design, it operates across a wide supply voltage range of ±2.25V to ±18V (dual-supply) or 4.5V to 36V (single-supply), making it versatile for industrial, medical, and audio systems. The device boasts a low input offset voltage of 25µV (typical) and 0.2µV/°C temperature drift, ensuring high DC accuracy. With a 10MHz gain bandwidth product (GBW) and 20V/µs slew rate, it balances speed and precision.
OPA2197IDR Operational Amplifier Applications
The OPA2197IDR excels in high-resolution data acquisition systems, sensor signal conditioning, and medical instrumentation. In high-precision DAQ systems, it amplifies microvolt-level signals from thermocouples, strain gauges, or pressure sensors with minimal error. For medical devices like ECG/EEG monitors, its low noise and high CMRR ensure clean extraction of biological signals. In audio equipment, it serves as a low-distortion preamplifier or active filter, delivering transparent sound reproduction. Industrial applications include motor control current sensing, 4–20mA loop transmitters, and battery management systems, where its stability and wide supply range are critical.
