The maximum output current of the DAC121S101 is 5mA. However, it's recommended to limit the output current to 3mA for optimal performance and to prevent overheating.
To ensure monotonicity, it's recommended to use a 0.1uF capacitor between the output pin and GND, and to use a 1kΩ resistor in series with the output pin. Additionally, the input code should be incremented or decremented in a monotonic sequence.
The settling time of the DAC121S101 is typically 10μs, but it can vary depending on the output voltage, load capacitance, and other factors. It's recommended to consult the datasheet and application notes for more information.
Yes, the DAC121S101 can be used with a 5V power supply. However, the output voltage range will be limited to 0-4.096V. If a 5V output is required, an external amplifier or voltage doubler may be necessary.
To reduce noise and glitches, it's recommended to use a low-pass filter (e.g. RC filter) at the output, and to ensure that the power supply is well-regulated and decoupled. Additionally, using a clock frequency that is a multiple of the DAC's update rate can help reduce noise.
