AD9626BCPZ-250

Analog To Digital Converters (ADC) Overview

The AD9626BCPZ-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 at 250 MSPS with a 70 MHz input, an Effective Number of Bits (ENOB) of 10.5 bits, and a Spurious-Free Dynamic Range (SFDR) of 80 dBc. Power dissipation is rated at 364 mW at the maximum sample rate. The component utilizes a 56-lead LFCSP package and supports selectable output data formats including offset binary, two's complement, and Gray code.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ-250 against the manufacturer's current ordering guide to confirm pinout compatibility and thermal specifications. Ensure that the procurement documentation matches the Rev. 0 datasheet parameters. Confirm RoHS compliance status through official channel partners or distributor certificates prior to finalizing acquisition orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when system requirements demand a 12-bit resolution with a sampling rate up to 250 MSPS. The internal reference and track-and-hold simplify board layout by reducing external component count. Consider the 56-lead LFCSP package constraints for thermal management and PCB space. Verify that the 1.8 V supply requirement aligns with the system's power architecture and that the CMOS output levels are compatible with the downstream logic.

Analog To Digital Converters (ADC) Part Context

The AD9626 belongs to a family of high-speed ADCs designed for wideband carrier and broadband systems. It is part of a pin-compatible series that includes lower-resolution variants such as the AD9601. The device is fabricated on an advanced CMOS process, ensuring robust performance across the industrial temperature range of -40°C to +85°C while maintaining low power dissipation characteristics suitable for portable and dense electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9601 is a pin-compatible alternative within the same family offering 10-bit resolution. Other models in the AD9626 series include the AD9626-170 and AD9626-210, which support lower maximum sampling rates of 170 MSPS and 210 MSPS respectively. Verify functional equivalence regarding pinouts and software configuration if substituting these variants.
