ADS4449IZCR

Analog To Digital Converters (ADC) Overview

The ADS4449IZCR is a quad-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a maximum sampling rate of 250 MSPS and utilizes a pipeline architecture. The device operates with an analog supply voltage range of 1.8V to 2V and a digital supply voltage range of 1.7V to 2V. It employs differential inputs and provides data output via LVDS serial interface. The component is housed in a 144-terminal NFBGA package measuring 10mm x 10mm. It supports synchronous sampling across its four channels and includes internal dithering capabilities.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel configuration with two independent pipeline modules
• High linearity designed for low power consumption and high SFDR
• Supports synchronous sampling across all four channels
• Integrated internal dithering mechanism

Analog To Digital Converters (ADC) Applications

• Multi-carrier GSM cellular infrastructure base stations
• Radar and smart antenna arrays
• Active antenna arrays for wireless infrastructures
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IZCR against the manufacturer's current orderable addendum to confirm package type and tape-and-reel specifications. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for any recent product change notices regarding packaging revisions or availability updates from Texas Instruments.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a quad-channel solution with 14-bit resolution and 250 MSPS throughput is required. Ensure the system design accommodates the 144-pin NFBGA footprint and the specific 1.8V/1.7V dual-supply voltage requirements. Verify that the LVDS serial interface aligns with the downstream FPGA or processor input capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS4449 belongs to the ADS44xx family of high-performance ADCs from Texas Instruments. It is distinct from single-channel variants like the ADS4149, offering four simultaneous conversion channels in a single package. This integration reduces board space compared to using multiple single-channel devices while maintaining high spectral performance.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the ADS44xx series or comparable high-speed quad-channel ADCs from other manufacturers if direct substitution is necessary.
