The OPA4197IDR is a precision amplifier with 36-V rail-to-rail input and output, low offset voltage op amp in a 14-lead surface-mount small-outline integrated circuit (SOIC). It is manufactured by Texas Instruments. The device offers excellent DC precision, rail-to-rail input and output to 36 V, low input offset voltage (3.3 mV max), and low power dissipation (1 mA) over the full specified temperature range of -40°C to 125°C. The op-amp offers a wide unity-gain bandwidth of 1.1 MHz, low supply current of 4.5 mA typical, and excellent CMRR of 130 dB. The OPA4197IDR is suitable for a wide range of precision applications such as industrial process control, communications, medical diagnostics, ultrasound, test and measurement, and consumer applications.
