Texas Instruments Spice Series Op Amps

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 (150V max) and drift (1.5VC) 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 OPA727OPA728 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, 30Vs slew rate and 0.0003 THDN 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 (IV-conversion) amplifiers for monitoring optical power in ONET applications.

Optimized for single-supply operation 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 to 12V.

The OPA727 (single) and OPA728 (single with shutdown) are available in MSOP-8 and DFN-8; the OPA2727 (dual) will be available in DFN-8 and SO-8, and the quad version OPA4727 will be available in TSSOP-14.

Production processing does not necessarily include testing of all parameters.

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.

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 10mA or less.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.

Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure.

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The TPA2012D2 only requires two external components for operation.The.
