AD9608BCPZ-125

Analog To Digital Converters (ADC) Overview

The AD9608BCPZ-125 is a dual-channel, 10-bit analog-to-digital converter (ADC) operating at sampling rates up to 125 MSPS. It utilizes a multistage differential pipeline architecture with output error correction logic to ensure no missing codes across the full temperature range. The device operates from a single 1.8 V analog supply and supports separate digital output driver supplies for 1.8 V CMOS or LVDS logic families. Key performance metrics include an SNR of 61.7 dBFS at 70 MHz and an SFDR of 85 dBc at 70 MHz. Power consumption is specified at 95 mW per channel at 125 MSPS. The component is housed in a 64-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation against the manufacturer's current ordering guide to confirm the exact speed grade and package variant. Ensure that the procurement documentation matches the required industrial temperature range specifications. Cross-reference the datasheet revision history to confirm compatibility with existing design files and pinout configurations before finalizing purchase orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution with 10-bit resolution and 125 MSPS throughput is required. Consider the available output formats, including offset binary, Gray code, or twos complement, based on downstream processing needs. Evaluate the power consumption requirements relative to the 95 mW per channel specification at maximum sampling rates. Verify compatibility with the 64-lead LFCSP footprint during PCB layout planning.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9608 family of dual-channel ADCs from Analog Devices. It shares pin compatibility with other converters in the series, such as the AD9650, AD9269, and AD9648, facilitating migration between different bit resolutions and sampling speeds. The device is designed to support applications requiring high performance in a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9608BCPZ-105 is a verified alternative within the same family, offering a 105 MSPS sampling rate instead of 125 MSPS. Both parts share identical pinouts and packaging, allowing for direct substitution if the lower sampling rate meets system requirements. Verify that the reduced bandwidth does not impact application performance.
