Key Features
- I2C-Compatible Serial Interface: Supports standard, fast, and high-speed modes, allowing for flexible communication with the host system.
- Pin-Selectable Addressing: Allows multiple devices to be connected to the same serial bus by selecting different I2C addresses.
- Automatic Shutdown: The device enters a low-power shutdown mode when not converting, reducing power consumption to 1 µA maximum at 3V.
- Out-of-Range Indicator/Alert Function: An open-drain output (ALERT) becomes active when the conversion result violates the programmed high or low limits, which can be used as an interrupt.
- Fast Conversion Time: 2 µs conversion time, enabling rapid data acquisition.
- Single-Ended Analog Input Channels: Each of the 8 channels can handle input frequencies up to 11 MHz.
Applications
- Industrial Automation: Suitable for monitoring and control systems in industrial environments due to its robust operating temperature range and low power consumption.
- Embedded Systems: Ideal for use in microcontroller-based systems requiring multiple analog input channels with I2C communication.
- Medical Devices: Can be used in medical equipment that requires precise analog-to-digital conversion with low power consumption.
- Aerospace and Defense: Applicable in various aerospace and defense applications where reliability and precision are critical.
