Evaluation Models

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS7A8300. Table 14 shows the summary information for this fixture.

Table 14. Design Kits and Evaluation Models

TPS7A8300EVM-579 Evaluation Module SBVU021

The EVM can be requested at the Texas Instruments web site through the TPS7A8300 product folder.

Spice Models

Computer simulation of circuit performance using SPICE is often useful when analyzing the performance of analog circuits and systems. A SPICE model for the TPS7A83A device is available through the TPS7A83A product folder under simulation models.

Electrostatic Discharge Caution


This integrated circuit can be damaged by ESD. 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.
