ADS4129IRGZR

Analog To Digital Converters (ADC) Overview

The ADS4129IRGZR is a single-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at sampling rates up to 250 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and supports both parallel CMOS and low-voltage differential signaling (LVDS) digital output interfaces. It functions on a single 1.8 V supply voltage for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of 72.2 dB, an effective number of bits (ENOB) of 11.7 bits, and a spurious-free dynamic range (SFDR) of 80 dB. The component is housed in a 48-lead VQFN package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRGZR' to confirm the reel packaging format and industrial temperature grade. Ensure compatibility with the 48-lead VQFN footprint during PCB layout. Confirm that the selected digital interface mode matches the downstream processing requirements before finalizing the order.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and minimal power dissipation is required. The ADS4129 is suitable for applications where space is constrained due to its compact QFN package. Consider the available development kit, such as the ADS4129EVM, for initial system validation and performance verification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS41xx family of ultralow-power ADCs from Texas Instruments. It shares architectural similarities with the ADS4126 and ADS41B29 but offers distinct interface options and power characteristics. The device is designed to address the growing demand for energy-efficient data conversion in portable and battery-operated wireless systems.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4126 serves as a functional alternative within the same product family. Designers should verify pinout compatibility and interface specifications when substituting parts.
