低压精密运算放大器
GT8531
The GT853X, GT8531, GT8532 and GT8534, family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the GT853X offset voltage and offset drift provide unparalleled long-term stability. With a mere 70 µA of quiescent current, the GT853X are able to achieve a 2-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 GT853X 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.
