Low voltage precision operational amplifier
GT8502
The GT850X, GT8501, GT8502 and GT8504, family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the GT850X offset voltage and offset drift provide unparalleled long-term stability. With a mere 7 µA of quiescent current, the GT850X are able to achieve a 45-KHz bandwidth. These small-size, high-precision operational amplifiers have high input impedance and rail-to-rail input and rail-to-rail output swing. The GT850X feature flat bias current over temperature. Therefore, no calibration is needed in high input impedance applications over temperature. All versions are specified over the temperature range of -40°C to +125°C.
