Key Features
- On-chip Reference: The device includes an on-chip 1.25 V or 2.5 V reference with a temperature coefficient of 5 ppm/°C, which can be enabled via a software write.
- Power-On Reset: Ensures that the DAC output powers up to 0 V or midscale and remains at this level until a valid write takes place.
- Power-Down Feature: Reduces current consumption to 400 nA at 5 V and provides software-selectable output loads while in power-down mode.
- Rail-to-Rail Output Amplifier: The output amplifier has rail-to-rail operation, ensuring full output voltage range.
- Asynchronous Clear (CLR): Updates all DACs to a user-programmable code—zero scale, midscale, or full scale—upon activation.
- Simultaneous Update: The outputs of all DACs can be updated simultaneously using the LDAC function.
Applications
- Industrial Control Systems: Suitable for applications requiring multiple precise analog outputs, such as in process control and automation.
- Medical Devices: Used in medical equipment where high accuracy and reliability are critical, such as in patient monitoring systems.
- Aerospace and Defense: Applicable in various military and aerospace applications due to its robust performance and reliability.
- Automotive Systems: Can be used in automotive control systems, including engine control units and other safety-critical systems.
