AD9628BCPZRL7-125

Analog To Digital Converters (ADC) Overview

The AD9628BCPZRL7-125 is a dual-channel, 12-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 guarantee no missing codes across the full industrial temperature range of −40°C to +85°C. The device features a high-performance sample-and-hold circuit and an on-chip voltage reference, powered by a single 1.8 V supply. Key electrical specifications include a signal-to-noise ratio (SNR) of 71.2 dBFS and a spurious-free dynamic range (SFDR) of 93 dBc at a 70 MHz input frequency. Power consumption is rated at 101 mW per channel at maximum speed. Digital outputs support 1.8 V CMOS or LVDS logic levels, with data formats configurable as offset binary, Gray code, or two's complement.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current datasheet to confirm reel packaging details and tape dimensions. Ensure the component matches the exact pinout and thermal pad requirements for the 64-lead LFCSP package. Cross-reference the revision history to confirm compatibility with existing design files.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution is required for applications needing 12-bit resolution at speeds up to 125 MSPS. Consider the 650 MHz analog input bandwidth and low power consumption of 101 mW per channel for battery-operated or thermally constrained designs. Verify that the available digital output formats meet the receiving logic requirements.

Analog To Digital Converters (ADC) Part Context

The AD9628 belongs to Analog Devices' family of high-speed, low-power ADCs designed for communications and instrumentation. It shares pin compatibility with other converters in the series, such as the AD9650 and AD9269, allowing for migration paths between different resolutions and speeds within the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible alternatives like the AD9628-105 if lower sampling rates suffice. Evaluate newer generations from the manufacturer for potential improvements in noise performance or power efficiency before substituting.
