Key Features
- Easy Drive Features: Relax the drive requirements of the analog front end (AFE) and reference circuitry, reducing the need for dedicated high-speed ADC drivers and reference buffers.
- High-Z Mode: Analog input high-Z mode and reference input high-Z mode simplify system designs and increase channel density.
- Overvoltage Protection: Input overvoltage protection clamps on each analog input protect the ADC from overvoltage events.
- On-Chip Reference Buffer: The WLCSP option includes an internal reference buffer, providing a true, buffered reference input.
- Advanced Digital Functionality: Compatible with low power digital hosts, featuring low SPI clock rate requirements, on-chip customizable channel sequencers, and oversampling and decimation.
- Autocycle Mode and Threshold Detection: Enable low power, interrupt-driven firmware design by performing conversions autonomously and generating alerts based on channel-specific threshold limits.
