ADC34J44IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J44IRGZ25 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 JESD204B serial interface and an internal clock divider for flexible system clock architecture. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 72.5 dBFS at fIN = 10 MHz and a Spurious-Free Dynamic Range (SFDR) of 93 dBc under the same conditions. Total power dissipation is typically 715 mW at maximum sampling rate.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel 14-bit resolution with 125 MSPS maximum sampling rate
• Ultra-low power consumption: 203 mW per channel at 160 MSPS equivalent scaling
• Internal Dither algorithm improves SFDR and noise floor
• 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 component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure the specific IRGZ25 suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 14-bit resolution and 125 MSPS throughput are required for high-linearity applications. Compare against ADC34J45 if higher 160 MSPS speeds are needed, or ADC34J42/43 for lower speed variants. Ensure the design accommodates the VQFN-48 package thermal characteristics and differential input voltage requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J4x family, which includes ADC34J42, ADC34J43, and ADC34J45. These devices share pin compatibility and functional blocks but differ in maximum sampling frequencies. The ADC34J44 specifically targets the 125 MSPS segment of the high-speed data converter market.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include ADC34J42, ADC34J43, and ADC34J45. Verify that the alternative's sampling rate meets system timing requirements before substitution.
