Key Features
- Easy Drive Features: Relaxes the drive requirements of the analog front end (AFE) and reference circuitry, reducing the need for dedicated high-speed ADC drivers and reference buffers.
- Overvoltage Protection: Input overvoltage protection clamps on each analog input protect the ADC from overvoltage events.
- On-Chip Reference Buffer: Available in the WLCSP option, 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: Enables low-power, interrupt-driven firmware design by performing conversions autonomously and generating alerts based on channel-specific threshold limits.
Applications
The AD4696 is optimal for use in space-constrained, multichannel, precision data acquisition systems and monitoring circuits. It is particularly suited for applications such as industrial automation, medical devices, and any scenario requiring high-performance, low-power, and compact ADC solutions.
