ADS6129IRGZR

Analog To Digital Converters (ADC) Overview

The ADS6129IRGZR is a single-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS and utilizes a pipeline architecture. The device features differential inputs and supports selectable parallel DDR LVDS or CMOS output interfaces. It requires a 3.3 V analog supply and a 1.7 V to 1.9 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 70.9 dB, an effective number of bits (ENOB) of 11.4, and power dissipation of 687 mW. It is housed in a 48-pin VQFN package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the reel packaging configuration as indicated by distributor listings. Confirm that the component meets RoHS compliance requirements for your target market. Ensure that the thermal characteristics of the exposed pad VQFN package are adequately addressed in the PCB layout design. Cross-reference the manufacturer's latest datasheet to confirm current production status and availability constraints before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel ADC with 250 MSPS throughput and 12-bit resolution is required. It is appropriate for applications needing flexible digital interface options between LVDS and CMOS. Consider the 3.3 V analog and 1.8 V digital supply requirements during power budgeting. Evaluate the 687 mW power dissipation against thermal management capabilities. Compare SNR and ENOB specifications against system dynamic range needs.

Analog To Digital Converters (ADC) Part Context

The ADS6129 belongs to the ADS61xx family of high-speed analog-to-digital converters. This series includes variants such as the ADS6128, which offers similar functionality but with a lower 210 MSPS sampling rate. Both devices share the same VQFN-48 package and pipeline architecture, allowing for potential design compatibility within product lines requiring different speed grades.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6128IRGZR is a confirmed substitute part number within the same family. It shares the identical VQFN-48 package and pinout but operates at a reduced sampling rate of 210 MSPS instead of 250 MSPS. Verify that the lower bandwidth of the ADS6128 meets the specific signal processing requirements of the application.
