Texas Instruments recommends following a star-grounding topology, keeping analog and digital grounds separate, and using a solid ground plane to minimize noise. Additionally, keep the input and output traces short and away from each other to reduce crosstalk.
The TLV2352IPW has a built-in POR and BOR circuitry. To handle these, ensure that the power supply ramps up slowly (typically 1-2 ms) and that the voltage stays above the BOR threshold (typically 1.9 V) during operation. You can also add external circuitry to detect and respond to POR and BOR events if needed.
The recommended operating temperature range for the TLV2352IPW is -40°C to 125°C. Operating outside this range may affect the amplifier's performance, including increased noise, reduced bandwidth, and decreased accuracy. Ensure that your design takes into account the temperature range and its impact on the amplifier's performance.
Choose gain resistors based on your desired gain and bandwidth requirements. A higher gain resistor value will result in higher gain but reduced bandwidth. Conversely, a lower gain resistor value will result in lower gain but increased bandwidth. Consult the datasheet and application notes for guidance on selecting the optimal gain resistors for your specific application.
To minimize EMI and RFI, use a shielded enclosure, keep the amplifier away from high-frequency sources, and use a low-pass filter or ferrite bead on the input and output lines. Additionally, ensure that your PCB layout follows good EMI/RFI design practices, such as keeping signal traces short and away from the edge of the board.
