Texas Instruments provides a recommended PCB layout in the PGA204AU/1KE4 evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The gain setting depends on the specific application requirements. The PGA204AU/1KE4 has a programmable gain amplifier, and the gain setting can be determined by considering factors such as the input signal amplitude, desired output signal amplitude, and noise tolerance. TI provides a gain calculation tool to help with this process.
The maximum input signal amplitude that the PGA204AU/1KE4 can handle is dependent on the gain setting and the supply voltage. According to the datasheet, the maximum input signal amplitude is typically 2.5Vpp differential, but this can be affected by the gain setting and other factors. It's recommended to consult the datasheet and perform simulations or testing to determine the maximum input signal amplitude for a specific application.
To ensure EMC with the PGA204AU/1KE4, it's recommended to follow proper PCB design and layout practices, such as using a solid ground plane, minimizing signal trace lengths, and using shielding and filtering components as needed. Additionally, TI provides EMC guidelines and recommendations in the PGA204AU/1KE4 datasheet and application notes.
The power consumption of the PGA204AU/1KE4 depends on the supply voltage, gain setting, and operating frequency. According to the datasheet, the typical power consumption is around 12mA at 5V supply voltage. To optimize power consumption for low-power applications, consider using a lower supply voltage, reducing the gain setting, and operating at a lower frequency. TI also provides power-saving modes and shutdown features that can be used to minimize power consumption.
