低压精密运算放大器
GT8571
The GT857X, GT8571, GT8572 and GT8574, family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the GT857X offset voltage and offset drift provide unparalleled long-term stability. With a mere 1.3 mA of quiescent current, the GT857X are able to achieve a 24-MHz bandwidth. These small- size, high-precision operational amplifiers have high input impedance and rail-to-rail input and rail-to-rail output swing. The GT857X 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.
