低压精密运算放大器
GT8521
The GT852X, GT8521, GT8522 and GT8524, family of precision amplifiers offers state-of-the-art performance. With chopper stabilized technique, the GT852X offset voltage and offset drift provide unparalleled long-term stability. With a mere 21 µA of quiescent current, the GT852X are able to achieve a 350KHz bandwidth. These small-size, high-precision operational amplifiers have high input impedance and rail-to-rail input and rail-to-rail output swing. The GT852X 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.
