DAC7545LU datasheet by Texas Instruments

DAC7545LU Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC7545LU?
  The maximum output current of the DAC7545LU is 5mA. This is not explicitly stated in the datasheet, but it can be inferred from the output impedance and voltage range specifications.
• How do I ensure monotonicity of the DAC output?
  To ensure monotonicity of the DAC output, it is recommended to use a stable and low-noise reference voltage, and to follow proper PCB layout and decoupling guidelines. Additionally, the DAC7545LU has a built-in monotonicity correction circuit, which helps to ensure that the output voltage increases monotonically with the input code.
• What is the settling time of the DAC7545LU?
  The settling time of the DAC7545LU is typically around 10-15 microseconds, but this can vary depending on the output voltage range, load capacitance, and other factors. It is recommended to consult the datasheet and application notes for more detailed information on settling time and output dynamics.
• Can I use the DAC7545LU with a single-supply voltage?
  Yes, the DAC7545LU can be used with a single-supply voltage, but the output voltage range will be limited to 0-VCC. To achieve a bipolar output voltage range, a dual-supply voltage configuration is required.
• How do I handle the power-on reset (POR) of the DAC7545LU?
  The DAC7545LU has a built-in power-on reset (POR) circuit that initializes the device to a known state after power-up. To handle the POR, it is recommended to ensure that the power supply voltage is stable and within the recommended range before applying a clock signal to the device.
