Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to PCB assembly. Ensure proper ESD handling precautions are observed due to the sensitivity of the QFN package. Cross-reference datasheet revisions to ensure compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a balance of 13-bit resolution and moderate sampling speed is required for portable applications. Consider the HMCAD1051-80 variant if higher sampling rates up to 80 MSPS are needed. Evaluate system jitter requirements carefully, as clock quality significantly impacts SNR performance. Verify that the output driver supply voltage (OVDD) matches the receiving logic levels.

Analog To Digital Converters (ADC) FAQ

What clock input formats does the HMCAD1051-40 support?

The device supports LVDS, LVPCLL, sine wave, and CMOS clock inputs. For CMOS inputs, the CKn pin should be connected to ground while the signal is applied to CKP.

How is the output data format configured?

The DFRMT pin selects the format. Connecting it to OVSS results in offset binary, while connecting it to OVDD results in two's complement output.

What is the aperture jitter specification?

The RMS aperture jitter is specified as less than 0.5 ps, which is critical for maintaining high SNR at elevated input frequencies.
