ADC34J24IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J24IRGZ25 is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 125 MSPS and utilizes a JESD204B serial interface. The device features an ultra-low power architecture with a single 1.8-V supply, consuming approximately 715 mW at full speed. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 70.1 dBFS and a Spurious-Free Dynamic Range (SFDR) of 93 dBc at fIN = 70 MHz. It supports multi-chip synchronization via SYSREF and includes internal dithering to improve dynamic performance.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel 12-bit resolution with 125 MSPS sampling rate
• JESD204B compliant serial interface supporting Subclass 0, 1, and 2
• Ultra-low power consumption: ~203 mW per channel at 160 MSPS equivalent
• Internal dither for improved SFDR and cleaner 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 specific suffix 'RGZ25' against the manufacturer's current orderable parts list to confirm package type and availability status. Ensure that the JESD204B configuration parameters, such as lane count and conversion rate, align with the system requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-linearity, low-power solution is required for multi-channel signal acquisition. The ADC34J24 offers a balance between speed and power efficiency compared to higher-speed variants like the ADC34J25. Verify that the input frequency range and dynamic range requirements fit within the specified SNR and SFDR limits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J2x family, which also includes the ADC34J22 (50 MSPS), ADC34J23 (80 MSPS), and ADC34J25 (160 MSPS). All members share pin compatibility and similar architectural features, differing primarily in their maximum sampling rates and associated power consumption profiles.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC34J23 (lower speed) or ADC34J25 (higher speed). For non-pin-compatible alternatives, consider the ADC3424 series, though interface differences (LVDS vs. JESD204B) must be evaluated.
