- High Oversampling Ratio: This reduces the external anti-alias requirements to first order in most cases.
- Flexible Interface: Supports parallel, SPI, and serial interfaces for versatile communication options.
- On-Chip Voltage Reference: A 2.5 V voltage reference is available on-chip, or an external reference can be used.
- Power-Down Mode: Reduces idle power consumption to 200 µW.
- Dual Input Modes: Allows for both unipolar and bipolar input ranges.
Applications
- Industrial Automation: Suitable for precision measurement and control systems.
- Medical Devices: Used in medical equipment requiring high accuracy and reliability.
- Aerospace and Defense: Applicable in various military and aerospace applications where precision and durability are critical.
- Test and Measurement: Ideal for use in precision measurement instruments and data acquisition systems.
