The combination of the OPA827 JFET op amp in this series provides excellent AC performance and excellent DC accuracy. These amplifiers feature low offset voltage (150μV, max), very low temperature drift (1.5μV/°C, typical), low bias current (15pA, typical), and very low noise from 0.1Hz to 10Hz (250nV).polypropylene, typical). The device operates over a wide supply voltage range and has low supply current (4.8mA/Ch, typical) over ± ± 4V to 18V.
Excellent AC features such as 22MHz gain-bandwidth product (GBW), a 28V/μs slew rate, and precision dc characteristics make the OPA827 family suitable for a wide range of applications including 16-bit to 18-bit mixed-signal systems, blocking (I/video conversion) amplifiers, filters, accuracy for ± 10V front-end and professional audio applications.
