(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods    may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less.
(3) Short-circuit to ground, one amplifier per package.

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 (150V max) and drift (1.5V/°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/s 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.

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 6A and features a reference pin for easy shutdown operation with standard CMOS logic in dual-supply applications.

For ease of use, the OPA727 and OP728 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) will be available Q4'04 in DFN-8 and SO-8, and the quad version OPA4727 will be available Q1'05 in TSSOP-14. All versions are specified for operation from −40°C to +125°C.
