ADC34J25IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J25IRGZ25 is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 160 MSPS with a single 1.8-V supply. The device features a JESD204B serial interface supporting up to 3.2 Gbps and includes an internal phase-locked loop for clock multiplication. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 69.6 dBFS at fIN = 70 MHz and a Spurious-Free Dynamic Range (SFDR) of 86 dBc. Power consumption reaches 812 mW at full speed.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel 12-bit resolution with 160 MSPS sampling rate
• JESD204B compliant serial interface with Subclass 0, 1, and 2 support
• Ultra-low power consumption: 203 mW per channel at 160 MSPS
• Internal dither algorithm to improve SFDR and noise floor

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 component status as obsolete or production data based on the latest manufacturer documentation. Confirm the VQFN-48 package availability and ensure compliance with RoHS standards. Check for moisture sensitivity level (MSL) requirements during storage and handling to prevent damage prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model for high-linearity applications requiring simultaneous sampling across four channels. Ensure the system clock architecture accommodates the flexible input clock buffer with divide-by-1, -2, or -4 options. Verify that the differential input voltage range matches the signal source specifications for optimal dynamic performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J2x family, which includes variants with different sampling rates such as the ADC34J22 (50 MSPS), ADC34J23 (80 MSPS), and ADC34J24 (125 MSPS). All members share pin compatibility and similar architectural features, allowing for design flexibility within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-to-pin compatible alternatives within the same family include the ADC34J24IRGZ25 for lower sampling rate requirements. For higher resolution needs, consider the 14-bit ADC34J4x series, though functional differences exist in bit depth and power characteristics.
