ADC3444IRTQ25

Analog To Digital Converters (ADC) Overview

The ADC3444IRTQ25 is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 125 MSPS with a single 1.8-V supply. The device features a serial low-voltage differential signaling (LVDS) interface and an internal phase-locked loop (PLL) for bit clock generation. Key performance metrics at 125 MSPS include a typical signal-to-noise ratio (SNR) of 72.9 dBFS and a spurious-free dynamic range (SFDR) of 88 dBc. It operates within a temperature range of -40°C to +85°C and is housed in a VQFN-56 package.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture with 14-bit resolution
• Serial LVDS interface with internal PLL
• Ultra-low power consumption: 475 mW total at 125 MSPS
• Supports multi-chip synchronization via SYSREF

Analog To Digital Converters (ADC) Applications

• Multi-carrier, multi-mode cellular base stations
• Radar and smart antenna arrays
• Software-defined radios (SDRs)
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTQ25' against the manufacturer's current orderable addendum to confirm availability and exact packaging details. Check for any recent production change notices (PCN) that may affect pin compatibility or electrical specifications. Ensure the source document matches the SBAS670A revision history for accurate parameter validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low power are required for multi-channel applications. Compare SNR and SFDR requirements against the 125 MSPS performance tables. Consider the VQFN-56 package size for board space constraints. Verify that the system clock architecture can accommodate the internal PLL and input clock divider options.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC344x family, which includes ADC3441, ADC3442, and ADC3443. These devices share pinout compatibility and architectural features but differ in maximum sampling rates. The ADC3444 represents the highest speed variant in this specific 14-bit series, supporting up to 125 MSPS.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include ADC3441, ADC3442, and ADC3443, provided the lower sampling rates meet system requirements. Cross-family alternatives like the ADC34J24 or ADC34J44 offer JESD204B interfaces instead of serial LVDS.
