DAC104S085CIMMX/NOPB datasheet by Texas Instruments

DAC104S085CIMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC104S085?
  The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
• How do I ensure accurate voltage output from the DAC104S085?
  To ensure accurate voltage output, it's essential to use a low-noise, low-impedance voltage reference (VREF) and to decouple the VREF pin with a capacitor. Additionally, ensure that the output load is within the specified range, and the output voltage is not loaded with a capacitive load.
• What is the maximum clock frequency for the DAC104S085?
  The maximum clock frequency for the DAC104S085 is 40 MHz. Exceeding this frequency may result in incorrect data conversion or device malfunction.
• How do I handle the DAC104S085's power-down mode?
  To enter power-down mode, assert the PD pin low. In this mode, the device consumes minimal power, but the output voltage is not guaranteed. When exiting power-down mode, ensure that the PD pin is de-asserted before applying a new input code to prevent output glitches.
• What is the thermal impedance of the DAC104S085 package?
  The thermal impedance (θJA) of the DAC104S085 package is approximately 48°C/W. This value is essential for estimating the device's junction temperature and ensuring reliable operation within the specified temperature range.
