Texas Instruments provides a recommended PCB layout in the DRV134PAG4 datasheet, but it's also important to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using decoupling capacitors.
The gain resistor (Rg) value depends on the desired gain and input impedance of the amplifier. TI provides a gain calculation formula in the datasheet, and you can use online calculators or simulation tools to determine the optimal Rg value for your specific application.
The maximum input signal amplitude is not explicitly stated in the datasheet, but it's limited by the device's input voltage range and the desired output signal amplitude. As a general rule, keep the input signal amplitude below 2Vpp to ensure linear operation and avoid clipping.
Yes, the DRV134PAG4 can be used as a line driver or a differential amplifier, depending on the application requirements. The device's high common-mode rejection ratio (CMRR) and high differential gain make it suitable for both applications.
To ensure EMC, follow proper PCB design and layout guidelines, use shielding and filtering components, and consider using a common-mode choke or ferrite bead to reduce electromagnetic interference (EMI). Additionally, ensure that the device is properly decoupled and bypassed.
