AD9626BCPZRL7-250

Analog To Digital Converters (ADC) Overview

The AD9626BCPZRL7-250 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices, optimized for high performance and low power consumption. It operates at a maximum conversion rate of 250 MSPS with a 700 MHz full-power analog bandwidth. The device features an integrated track-and-hold amplifier and voltage reference, requiring only a single 1.8 V supply for both analog and digital sections. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 64.8 dBFS and an Effective Number of Bits (ENOB) of 10.5 bits at an input frequency up to 70 MHz. It offers selectable output data formats including offset binary, two's complement, and Gray code.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the -250 variant matches the required 250 MSPS speed grade against the datasheet ordering guide. Ensure the LFCSP-56 package type aligns with PCB footprint requirements. Check RoHS compliance status as per the manufacturer's current documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for wideband carrier and broadband systems requiring outstanding dynamic performance. Consider the interleaved dual-port mode if system architecture benefits from half-sample-rate operation. Evaluate power dissipation levels relative to thermal constraints in the final enclosure design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9626 family of 1.8 V ADCs, which also includes variants operating at 170 MSPS and 210 MSPS. The AD9626 is pin-compatible with the 10-bit AD9601, facilitating design flexibility across resolution requirements within the same package form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the AD9626-170 and AD9626-210, though these operate at lower maximum sample rates. For pin-compatible alternatives with different resolution, the AD9601 series may be considered.
