ADS4229IRGC25

Analog To Digital Converters (ADC) Overview

The ADS4229IRGC25 is a dual-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 250 MSPS with an ultralow power consumption of 545 mW using a single 1.8-V supply. The device features high dynamic performance, including an 80.8-dBc spurious-free dynamic range (SFDR) at 170 MHz and a crosstalk specification exceeding 90 dB at 185 MHz. It supports both DDR LVDS and parallel CMOS digital output interfaces within a compact 64-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '25' against the manufacturer's current documentation to confirm package type and reel specifications. Confirm availability status as this component may be subject to discontinuation or limited stock constraints in certain regions.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS4229 for applications requiring low power and high dynamic performance in multi-carrier environments. Ensure the system design accommodates the 1.8-V single supply requirement and utilizes the internal reference to eliminate external decoupling capacitors.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS42xx family of ultralow-power ADCs. It serves as a successor to the ADS62P49, offering pin compatibility but requiring adjustments for supply voltage differences and the removal of external reference support.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4229 is pin-compatible with the previous generation ADS62P49 data converter. Migration requires accounting for changes in AVDD supply voltage and the handling of previously connected pins which must now be floated.
