Texas Instruments OPA2251UA Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers Overview
Dual, general-purpose operational amplifier featuring a 35kHz bandwidth and 120dB voltage gain. This 2-channel IC operates from a single supply of 2.7V to 36V or dual supplies from ±1.35V to ±18V, with a low operating supply current of 27µA. It offers a 100µV input offset voltage and 20nA input bias current, with a 0.01V/µs slew rate.
Packaged in an 8-SOIC surface-mount case with gull wing terminals, this industrial-grade component is RoHS compliant and operates from -40°C to 85°C.
