LMC6035IBPX datasheet by Texas Instruments

LMC6035IBPX Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the LMC6035IBPX?
  Texas Instruments recommends a compact layout with the LMC6035IBPX placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is driving. The device should be placed on a solid ground plane, and the input and output traces should be kept short and away from noise sources.
• How do I handle the thermal dissipation of the LMC6035IBPX?
  The LMC6035IBPX has a thermal pad on the bottom of the package that should be connected to a solid ground plane or a thermal relief pattern on the PCB. Additionally, the device should be placed in a well-ventilated area, and the PCB should be designed to allow for good airflow.
• What is the recommended power-up sequence for the LMC6035IBPX?
  The recommended power-up sequence is to first apply the analog supply voltage (VCC) and then the digital supply voltage (VDD). The power-up sequence should be controlled to prevent the device from being powered up with an invalid input voltage.
• How do I filter the output of the LMC6035IBPX to reduce noise?
  The output of the LMC6035IBPX can be filtered using a low-pass filter, such as an RC filter or an active filter. The filter should be designed to have a cutoff frequency that is above the frequency of interest and below the Nyquist frequency of the ADC or DAC.
• What is the recommended input impedance for the LMC6035IBPX?
  The recommended input impedance for the LMC6035IBPX is 1 kΩ or higher. This ensures that the device can drive the input capacitance of the ADC or DAC and maintain a stable output voltage.
