ADC3424IRTQ25

Analog To Digital Converters (ADC) Overview

The ADC3424IRTQ25 is a quad-channel, 12-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). Key performance metrics include a signal-to-noise ratio (SNR) of 70.2 dBFS and a spurious-free dynamic range (SFDR) of 87 dBc at an input frequency of 70 MHz. It operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture with 12-bit resolution
• Serial LVDS interface for high-density integration
• Internal PLL and flexible clock buffer with divide-by-1, -2, or -4 options
• Supports multi-chip synchronization via SYSREF input

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 orderable addendum to confirm package dimensions and tape-and-reel specifications. Ensure that the ordering information matches the current revision of the SBAS673A datasheet to avoid discrepancies in mechanical data.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a system requires four synchronized channels operating at speeds up to 125 MSPS. The ADC3424 is part of the ADC342x family; verify compatibility with other family members if pin-to-pin substitution with lower-speed variants like the ADC3421 or ADC3422 is considered.

Analog To Digital Converters (ADC) Part Context

The ADC3424 belongs to the ADC342x family, which includes the ADC3421 (25 MSPS), ADC3422 (50 MSPS), and ADC3423 (80 MSPS). All devices share the same VQFN-56 package and functional block diagram, differing primarily in their maximum sampling clock frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3424IRTQT is a direct pin-compatible alternative within the same family. Verify that the specific suffix requirements match the target application before substituting.
