DAC81401PWR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the DAC81401PWR evaluation module user's guide (SLAU445). It's essential to follow this guide to minimize noise and ensure optimal performance.
  • To achieve a bipolar output, you can use an external op-amp to level-shift and amplify the output of the DAC81401PWR. Texas Instruments provides an example circuit in the DAC81401PWR datasheet (SLAS634).
  • The maximum update rate of the DAC81401PWR is 1 MSPS. To achieve this rate, you need to use the SPI interface and ensure that the clock frequency is at least 20 MHz. Additionally, you should minimize the time between consecutive writes to the DAC register.
  • It's essential to follow proper power supply decoupling and bypassing techniques. Texas Instruments recommends using a 10 μF ceramic capacitor and a 1 μF ceramic capacitor in parallel, placed as close as possible to the power pins of the DAC81401PWR.
  • The DAC81401PWR's performance is affected by temperature, with a typical temperature coefficient of ±3 ppm/°C. To compensate for temperature effects, you can use an external temperature sensor and adjust the DAC output accordingly. Alternatively, you can use a temperature-compensated voltage reference.
