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 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/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 500pA, they are well suited for use as transimpedance (I/V-conversion) amplifiers for monitoring optical power in ONET applications.

Optimized for single-supply operation up to 12V, the input common-mode range extends to GND for true single-supply functionality. The output swings to within 150mV of the rails, maximizing dynamic range. The low quiescent current of 4.3mA makes it well-suited for use in battery-operated equipment. The OPA728 shutdown version reduces the quiescent current to typically 6µA and features a reference pin for easy shutdown operation with standard CMOS logic in dual-supply applications.

For ease of use, the OPA727 and OPA728 op amp families are fully specified and tested over the supply range of 4V to 12V. The OPA727 (single) and OPA728 (single with shutdown) are available in MSOP-8 and DFN-8; the OPA2727 (dual) is available in DFN-8 and SO-8; and the quad version OPA4727 in TSSOP-14. All versions are specified for operation from -40°C to +125°C.
