ADS41B29IRGZT

Analog To Digital Converters (ADC) Overview

The ADS41B29IRGZT is a single-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS using a pipeline architecture. The device accepts differential analog inputs and features parallel LVDS outputs. It requires 1.8 V for both analog and digital power supplies. Key performance metrics include a signal-to-noise ratio (SNR) of 73.6 dB, an effective number of bits (ENOB) of 11.8 bits, and a spurious-free dynamic range (SFDR) of 84.5 dB. Power consumption is 325 mW. It functions within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a low-power 14-bit pipeline ADC core optimized for high-speed data acquisition.
• Supports flexible input configurations with differential signaling capabilities.
• Provides parallel LVDS output interfaces for direct connection to high-speed processors or FPGAs.

Analog To Digital Converters (ADC) Applications

• Wireless infrastructure base stations
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZT' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with the operational environment specifications. Ensure compatibility with the 1.8 V supply rails before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 14-bit conversion is required at 250 MSPS. Compare against the ADS4149 if lower power consumption is prioritized over slightly different dynamic range characteristics. Ensure the system design supports the parallel LVDS interface requirements and the thermal dissipation needs associated with 325 mW power consumption.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS41Bxx family of low-power, 14-bit, 250 MSPS ADCs. It shares architectural similarities with the ADS4149 but differs in channel count and specific performance parameters such as SFDR. The family is designed for demanding RF applications requiring high linearity and speed.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4149IRGZT: Single-channel alternative with potentially different power/performance trade-offs. ADS4125IRGZT: Lower resolution (12-bit) option for cost-sensitive designs. Verify pinout and register compatibility before substitution.
