OPA827 低噪声、高精度、JFET 输入运算放大器
The OPA827 series of JFET operational amplifiers combine outstanding dc precision with excellent ac performance. These amplifiers offer low offset voltage (150uV, max), very low drift over temperature (1.5uV/°C, typ), low bias current (15pA, typ), and very low 0.1Hz to 10Hz noise (250nVPP, typ). The device operates over a wide supply voltage range, ±4V to ±18V on a low supply current (4.8mA/Ch, typ).
Excellent ac characteristics, such as a 22MHz gain bandwidth product (GBW), a slew rate of 28V/us, and precision dc characteristics make the OPA827 series well-suited for a wide range of applications including 16-bit to 18-bit mixed signal systems, transimpedance (I/V-conversion) amplifiers, filters, precision ±10V front ends, and professional audio applications
