HMCAD1511

Analog To Digital Converters (ADC) Overview

The HMCAD1511 is an 8-bit high-speed analog-to-digital converter (ADC) utilizing time-interleaving to achieve sampling rates from 30 MSPS to 1 GSPS. It supports single, dual, and quad channel modes with maximum sampling frequencies of 1000 MSPS, 500 MSPS, and 250 MSPS, respectively. The device features integrated cross-point switches for flexible input assignment, internal low-jitter programmable clock dividers, and internal reference circuitry requiring no external components. Digital gain ranges from 1X to 50X, providing a Signal-to-Noise Ratio (SNR) of 49.8 dB at 1X gain and 48 dB at 10X gain. Total power dissipation is 710 mW at 1000 MSPS including I/O. It operates on a 1.8 V supply with 1.7–3.6 V CMOS logic control interface pins and outputs serial LVDS/RS DS data in a 7x7 mm QFN-48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm packaging type and reel specifications. Ensure compatibility with the required voltage levels for the control interface and analog supplies before finalizing procurement. Confirm that the component meets RoHS compliance standards relevant to your manufacturing region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a versatile ADC with configurable channel counts and high sampling rates is required. Consider the trade-off between channel count and sampling speed inherent in the multi-mode design. Verify that the system can accommodate the pipeline delays associated with single, dual, or quad channel operations for proper FPGA synchronization.

Analog To Digital Converters (ADC) Part Context

The HMCAD1511 belongs to Analog Devices' family of high-speed, low-power ADCs designed for demanding signal processing applications. It shares pin compatibility with the HMCAD1520 and can be configured to operate similarly to the HMCAD1510, offering flexibility in system design while maintaining consistent physical footprint requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The HMCAD1520 is a pin-compatible alternative within the same product family. Additionally, the HMCAD1511 can be configured to operate as an HMCAD1510; however, functionality and performance should be verified against the HMCAD1510 datasheet for specific application requirements.
