GT8551数据手册GTIC中文资料规格书

描述 Description

The GT855X, GT8551, GT8552 and GT8554, family of precision amplifiers offers state-of-the-art performance. With zero-drift technology, the GT855X offset voltage and offset drift provide unparalleled long-term stability. With a mere 190 uA of quiescent current, the GT855X are able to achieve a 6-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 GT855X feature flat bias current over temperature. Therefore, no calibration is needed in high input impedance applications over temperature.

All versions are specified over the industrial temperature range of -40°C to +125°C.
