Key Features
- Dual 16-bit Buffered Voltage Output DACs: Provides high-resolution digital-to-analog conversion with rail-to-rail output amplifiers.
- Low Power Consumption: Typically 400 nA in power-down mode at 5 V.
- Power-On Reset and Power-Down Feature: Ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place. Software-selectable power-down mode with output loads.
- Simultaneous Update of DAC Outputs: The LDAC function allows updating all DACs simultaneously, with user-selectable DAC channels.
- Asynchronous Clear Function: Clears all DACs to a software-selectable code—0 V, midscale, or full scale.
- External Reference Input: Reference buffer provided on-chip with external reference input pins.
Applications
- Industrial Automation: For precise control and measurement in industrial automation systems.
- Medical Devices: Suitable for medical equipment requiring high accuracy and low power consumption.
- Aerospace and Defense: Used in various aerospace and defense applications where high resolution and reliability are critical.
- Test and Measurement Equipment: Ideal for test and measurement instruments that require precise analog output.
