OPA4727A Datasheet PDF - Burr Brown

●DESCRIPTION

●The OPA727 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 (150µV max) and drift (1.5µV/°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 OPA727/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/µs slew rate and 0.0003% THD+N make the OPA727 and OPA728 well-suited for communication, high-end audio, and active filter applications. With a bias current of less than 100pA, they are ideal for use as transimpedance (I/V-conversion) amplifiers for monitoring optical power in ONET applications.
