Analog To Digital Converters (ADC) FAQ

How does the ADC12DJ2700 handle input signal calibration?

Offset calibration eliminates internal DC offsets during initialization. For accurate results, the input signal should ideally be disabled or known during offset calibration. Linear/gain calibration can be performed without disconnecting the input signal.

What is the maximum data rate supported by the JESD204B interface?

The serial output channels support data rates up to 12.8 Gbps. The interface allows for up to 16 lanes, which can be configured to balance bitrate and channel count.

Can the device operate in both single and dual-channel modes?

Yes, the device is configurable. It operates at up to 5.4 GSPS in single-channel mode and up to 2.7 GSPS in dual-channel mode, allowing designers to choose based on bandwidth or channel density needs.
