ADC34J43IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J43IRGZ25 is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 80 MSPS with a single 1.8-V supply. The device features an ultra-low power consumption of 584 mW and supports flexible input clock division by 1, 2, or 4. It utilizes a JESD204B serial interface to reduce interconnect complexity and includes internal dithering for improved spurious-free dynamic range. Designed for high linearity, it provides channel isolation of 105 dB and supports multi-chip synchronization via SYSREF.

• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as production data before procurement planning. Confirm that the VQFN-48 package dimensions match the design footprint. Ensure the system power supplies provide stable 1.8 V rails within the recommended operating conditions. Check for moisture sensitivity level requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent channels are required at 80 MSPS. Compare against ADC34J42 for lower speed or ADC34J44 for higher speed needs. Verify that the JESD204B lane configuration meets the system bandwidth requirements. Consider the thermal resistance metrics if operating in enclosed environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J4x family, which includes variants with different sampling rates such as the ADC34J42 (50 MSPS), ADC34J44 (125 MSPS), and ADC34J45 (160 MSPS). All members share the same pinout and register map, facilitating pin-to-pin compatibility across the series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC34J42, ADC34J44, and ADC34J45. These parts maintain identical packaging and electrical interfaces but differ in maximum sampling frequency.
