OPA703UA

OPA703UA Description

The OPA703UA from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) designed for precision analog applications. Packaged in an 8-SOIC tube, this single-channel op-amp operates over a 4V to 12V supply range, making it versatile for both low-voltage and moderate-voltage systems. With an ultra-low input bias current of 1 pA and a minimal input offset voltage of 160 µV, the OPA703UA ensures high accuracy in signal conditioning and sensor interfacing. Its 1 MHz gain bandwidth product (GBW) and 0.6V/µs slew rate enable stable performance in bandwidth-sensitive applications. The device is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
