TLV1544CDR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a dedicated analog ground plane, and to keep the analog and digital signals separate. The analog input traces should be short and direct, 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.
  • The POR and BOR features of the TLV1544CDR can be handled by connecting the POR pin to a capacitor and a pull-up resistor to VCC. The capacitor should be chosen to ensure that the POR pin is held low for at least 1ms after power-on. The BOR threshold can be adjusted by connecting a resistor divider network to the BOR pin.
  • The recommended clock frequency for the TLV1544CDR is between 1.5MHz and 4MHz. A crystal oscillator or a high-quality clock source is recommended to ensure accurate conversions. The clock source should be connected to the CLKIN pin, and the clock frequency should be chosen based on the desired conversion rate and system requirements.
  • The TLV1544CDR has a built-in calibration feature that can be initiated by writing to the calibration register. The device should be calibrated after power-on and after any changes to the reference voltage or clock frequency. The calibration process involves a self-test and adjustment of the internal bias voltages and currents to ensure optimal performance.
  • The recommended reference voltage for the TLV1544CDR is between 2.5V and 5V. The reference voltage should be connected to the REF pin, and a bypass capacitor should be connected between the REF pin and the analog ground plane to filter out noise. The reference voltage should be chosen based on the desired conversion range and system requirements.
