概覽
The THS4130EVM is a good example of PCB design and layout for high-speed operational amplifier applications. It is a complete circuit for the high-speed operational amplifier. The EVM is mad eof the THS4130 high-speed operational amplifier, a number of passive components, and various featues and footprints that enable the user to experiment, test, and verify varous operational amplifier circuit implementations. The board measures 4.5 inces in length by 2.5 inces in width. Initially, this board is populated for a single-ended input amplifier. The outputs (Vo+ af Vo-) can be tested differentially or single ended. Gain is set to one and can be changed by changing the ratios of the feedback and gain resistors (see the device datasheet for recommended resistor values). The user may populate various footprints on the evaluation module board to verify filter designs or perform other experiments. Each input is terminated with a 50-ohm resistor to provide correct line-impedance matching.
This device is CE compliant.
