GT8562
The GT856X, GT8561, GT8562 and GT8564, family of
precision amplifiers offers state-of-the-art performance. With zero-drift technology, the GT856X offset voltage
and offset drift provide unparalleled long-term stability. With a mere 720 µA of quiescent current, the GT856X
are able to achieve a 17-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 GT856X 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.
