Description
The ADS7822U is a 12-bit, 8-channel, successive approximation (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates on a single 2.7V to 5V supply, making it suitable for low-power and portable applications.
Key features:
- 8 single-ended or 4 differential inputs (software-configurable).
- Serial I²C interface for easy microcontroller integration.
- Low power consumption (0.5mW at 5V, 100kSPS).
- Internal reference (2.5V) or external reference support.
- Auto-scan mode for sequential channel conversion.
Applications include battery monitoring, data acquisition, and industrial control systems. Its compact MSOP-8 package saves board space.
For detailed specs, refer to the datasheet (TI document SBAS199).
