OPA2192IDR – TEXAS INSTRUMENTS

The Texas Instruments OPA2192IDR is a single, precision, rail-to-rail input/output operational amplifier housed in a space-saving 8-pin SOIC package. It boasts a very low input bias current of typically 10 pA, crucial for high-impedance applications minimizing input offset errors. Its ultra-low input offset voltage of ±10µV ensures exceptional accuracy in sensitive instrumentation. The device operates from a ±2.5V to ±18V supply range, or a single supply from 5V to 36V, providing flexibility in various power schemes. The OPA2192IDR exhibits a gain-bandwidth product of 10 MHz and a slew rate of 10V/µs, making it suitable for moderate-speed applications requiring high precision. Its rail-to-rail capability maximizes dynamic range, particularly beneficial in sensor interfacing and signal conditioning circuits. Common applications include precision instrumentation amplifiers, low-noise data acquisition systems, and high-resolution analog-to-digital converter (ADC) input buffers. The OPA2192IDR’s advantages lie in its combination of low offset voltage, low bias current, and wide supply voltage range, making it a superior choice when accuracy and low noise are paramount, even with limited power supply options.
