AD9608BCPZRL7-105

Analog To Digital Converters (ADC) Overview

The AD9608BCPZRL7-105 is a dual-channel, 10-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 105 MSPS with a single 1.8 V analog supply and supports 1.8 V CMOS or LVDS digital outputs. The device features a differential pipeline architecture with output error correction logic to ensure no missing codes across the full operating temperature range of −40°C to +85°C. Key electrical specifications include an SNR of 61.7 dBFS at 70 MHz input frequency and an SFDR of 85 dBc. Power consumption is rated at 95 mW per channel at the maximum sampling rate. The component is housed in a 64-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 corresponds to reel packaging requirements when sourcing this component. Confirm that the -105 speed grade matches the system timing constraints, as the AD9608 family also includes a -125 variant. Ensure the LFCSP-64 thermal pad is properly soldered to the ground plane to maintain specified thermal resistance and electrical performance during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel 10-bit ADC with 105 MSPS throughput is required. The device is pin-compatible with other ADI converters ranging from 10-bit to 16-bit resolutions, facilitating migration paths within the same footprint. Consider the LVDS output option if signal integrity over longer traces is critical, or CMOS mode for simpler interfacing with standard logic families.

Analog To Digital Converters (ADC) Part Context

The AD9608 belongs to Analog Devices' high-speed data converter portfolio, utilizing a patented sample-and-hold circuit. It is part of a broader family that includes variants like the AD9608-125 and other bit-resolution models such as the AD9648 and AD9268. This integration allows designers to scale resolution and speed while maintaining consistent board layouts and design methodologies across different application requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9608BCPZ-105 is a direct functional equivalent with identical specifications but may differ in packaging format (tray vs. reel). Other members of the AD9608 family, such as the AD9608BCPZ-125, offer higher sampling rates but require verification of thermal and timing constraints.
