TLV5638CDR datasheet by Texas Instruments

TLV5638CDR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the TLV5638CDR?
  The recommended layout and routing for the TLV5638CDR involves keeping the analog and digital grounds separate, using a star-ground configuration, and minimizing the length of the analog input traces to reduce noise and interference.
• How do I ensure accurate voltage reference performance?
  To ensure accurate voltage reference performance, it is recommended to decouple the VREF pin with a 10nF capacitor to GND, and to use a low-impedance voltage source for the VCC pin.
• What is the maximum clock frequency for the TLV5638CDR?
  The maximum clock frequency for the TLV5638CDR is 20MHz, but it can be overclocked up to 30MHz with some degradation in performance.
• How do I handle the digital output data from the TLV5638CDR?
  The digital output data from the TLV5638CDR is in 2's complement format, and it is recommended to use a FIFO or a buffer to handle the data to avoid data loss or corruption.
• What is the power-on reset behavior of the TLV5638CDR?
  The TLV5638CDR has a power-on reset (POR) circuit that resets the device to a known state when the power supply voltage rises above 1.5V. The POR circuit ensures that the device starts up in a known state and prevents any unexpected behavior.
