TLV5636CDGKR datasheet by Texas Instruments

TLV5636CDGKR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the TLV5636CDGKR to minimize noise and ensure accurate conversions?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. The analog input traces should be short and shielded, and the digital output traces should be routed away from the analog inputs. Additionally, decoupling capacitors should be placed close to the device to filter out noise.
• How do I handle the internal reference voltage of the TLV5636CDGKR, and what are the implications of using an external reference?
  The internal reference voltage of the TLV5636CDGKR is 2.5V, and it can be bypassed with an external reference voltage between 2.5V and 5V. However, using an external reference may affect the accuracy and linearity of the conversions. It's recommended to use the internal reference voltage unless a specific application requires a different reference voltage.
• What is the maximum clock frequency that can be used with the TLV5636CDGKR, and what are the implications of using a higher clock frequency?
  The maximum clock frequency for the TLV5636CDGKR is 20 MHz. Using a higher clock frequency may result in increased power consumption, noise, and decreased accuracy. It's recommended to use a clock frequency between 10 kHz and 20 MHz for optimal performance.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) features of the TLV5636CDGKR?
  The TLV5636CDGKR has a built-in POR and BOR circuitry that resets the device during power-on and brown-out conditions. The POR threshold is 1.5V, and the BOR threshold is 1.2V. The device will reset when the supply voltage falls below these thresholds, and will remain in reset until the voltage rises above the threshold. It's recommended to use an external reset circuitry to ensure a clean reset signal.
• What is the recommended operating temperature range for the TLV5636CDGKR, and how does temperature affect its performance?
  The recommended operating temperature range for the TLV5636CDGKR is -40°C to 125°C. Temperature affects the device's performance, with increased temperature resulting in decreased accuracy and increased power consumption. It's recommended to operate the device within the specified temperature range for optimal performance.
