Instructions for Use:
Power Supply:
- Connect the supply voltage (VDD) to the power pin.
- Ensure the supply voltage is within the specified range (4.5V to 5.5V).
Reference Voltage:
- Connect the reference voltage (VREF) to the reference input pin.
- The reference voltage should be within the range of 0V to 5V.
Digital Inputs:
- Apply logic high (2.0V to VDD) or logic low (0V to 0.8V) signals to the digital input pins.
Output Configuration:
- The output current (IOUT) can be up to 20mA continuously.
- Ensure the load impedance is appropriate for the output current.
Power Consumption:
- In active mode, the device consumes approximately 30μA.
- To reduce power consumption, use the shutdown mode which reduces power to about 1μA.
Temperature Considerations:
- The device operates within a temperature range of -40°C to 85°C.
Resolution and Linearity:
- The AD7581JN has a 12-bit resolution.
- Ensure that the differential nonlinearity (DNL) and integral nonlinearity (INL) are within the specified limits to maintain accuracy.
Settling Time:
- The settling time for the output to reach 0.1% of the final value is approximately 10μs.
Output Impedance:
- The output impedance is very low (0.1Ω), making it suitable for driving various loads.
Handling Precautions:
- Handle the device with care to avoid static damage.
- Follow standard ESD precautions when handling and soldering the device.
By following these parameters and instructions, you can ensure optimal performance and reliability of the AD7581JN.
