HMCAD5831LP9BE

Analog To Digital Converters (ADC) Overview

The HMCAD5831LP9BE is a 3-bit, 26 GSPS analog-to-digital converter featuring an overrange bit, data inhibit function, and 1:2 demultiplexer. It operates with -5 V analog and -3.3 V digital supplies, consuming approximately 4.2 W of power. The device provides a 20 GHz input bandwidth and supports Nyquist operation up to 26 GSPS. Differential CML outputs are available with programmable swing via external VREF resistors. Integral and differential nonlinearity are specified at ±0.5 LSBs. The component utilizes a 64-lead, 9 x 9 mm SMT package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package marking and lead finish specifications. Confirm thermal management requirements, as the device dissipates significant power and requires a dedicated heat sink attached to the exposed pad. Ensure supply voltages match the -5 V and -3.3 V rails defined in the operating conditions table before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed, low-resolution digitization is required for broadband signals. The 3-bit resolution limits amplitude precision but enables extreme sampling rates. Designers must account for the 4.2 W power dissipation and implement robust PCB thermal vias connected to a bottom-side heat sink. Verify that the system clock jitter is sufficiently low to maintain the specified ENOB at the target input frequency.
