Schematic Editor Display Figure 2 shows the schematic editor layout The empty workspace on the sheet is the design window where you build the test circuit Below the Schematic Editor title bar is an operational menu row with selections such as file operations analytical operations test and measurement equipment selection etc Located just below the menu row is a row of icons associated with different file and TINA tasks The final row of icons allows you to select a specific component group These component groups contain basic passive components semiconductors and even sophisticated device macromodels These groups are accessed to build the circuit schematic 3 Building a Circuit with TINA TI To illustrate how easy it is to use TINA TI we will build an analog circuit and demonstrate some of the circuit analysis capabilities For this example a high output 1kHz sine wave oscillator circuit is selected A search through a circuit application handbook provides a number of op amp based designs We will build and simulate a Wien bridge oscillator with amplitude stabilization using the software A Texas Instruments OPA743 12V CMOS op amp is selected for the circuit application This amplifier is well suited for this design and provides very good dc and ac performance It operates with supplies of 3 5V to 12V our example requires 5V 10V SBOU052A August 2007 Revised August 2008 Getting Started with TINA TI 3 Submit Documentation Fe
