OPA728 电子微调 20MHz、高精度 CMOS 运算放大器
The OPA728 and OPA728 series op amps use a state-of-the-art 12V analog CMOS process and e-trim, a package-level trim, offering outstanding dc precision and ac performance. The extremely low offset (150uV max) and drift (1.5uV/°C) are achieved by trimming the IC digitally after packaging to avoid the shift in parameters as a result of stresses during package assembly. To correct for offset drift, the OPA728 and OPA728 family is trimmed over temperature. The devices feature very high CMRR and open-loop gain to minimize errors.
Excellent ac characteristics, such as 20MHz GBW, 30V/us slew rate and 0.0003% THD+N make the OPA728 and OPA728 well-suited for communication, high-end audio, and active filter applications
