DAC80P-CBI-V datasheet by Texas Instruments

DAC80P-CBI-V Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC80P-CBI-V?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
• How do I handle the output voltage range of the DAC80P-CBI-V?
  The DAC80P-CBI-V has an output voltage range of 0 to VREF. To ensure accurate output, it's essential to select a suitable reference voltage (VREF) and consider the output impedance of the device when designing the output stage.
• What is the purpose of the SYNC pin, and how do I use it?
  The SYNC pin is used to synchronize the DAC's output with an external clock signal. It allows the DAC to update its output on the rising edge of the SYNC signal, ensuring synchronized output with other devices in the system.
• How do I implement a bipolar output configuration with the DAC80P-CBI-V?
  To achieve a bipolar output, you need to use an external amplifier and a voltage reference. The DAC's output is connected to the inverting input of the amplifier, and the non-inverting input is connected to a voltage reference. The amplifier's output will then provide a bipolar signal.
• What is the maximum clock frequency supported by the DAC80P-CBI-V?
  The DAC80P-CBI-V supports clock frequencies up to 40 MHz. However, the actual clock frequency may be limited by the specific application and the quality of the clock signal.
