ADC34J45IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC34J45IRGZ25 is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 160 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 at 160 MSPS include a typical Signal-to-Noise Ratio (SNR) of 72 dBFS and a Spurious-Free Dynamic Range (SFDR) of 86 dBc. Total power dissipation is typically 812 mW. It operates within a temperature range of -40°C to +85°C and is housed in a VQFN-48 package.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel 14-bit resolution with 160 MSPS maximum sampling rate
• JESD204B serial interface supporting Subclass 0, 1, and 2
• Ultra-low power consumption: 203 mW per channel at 160 MSPS
• Internal dither algorithm and multi-chip synchronization support

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 ordering suffix 'RGZ25' against the manufacturer's current orderable addendum to confirm package type and tape-and-reel specifications. Confirm that the component status remains active or production data as required by the design lifecycle. Ensure compatibility with existing PCB footprints for the VQFN-48 package.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent high-speed channels are required. The ADC34J45 is optimized for input frequencies up to 450 MHz. Verify that the system clock architecture can accommodate the internal divide-by-1, -2, or -4 options. Ensure the host processor supports the JESD204B protocol for lane serialization.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J4x family, which includes variants with different sampling rates such as the ADC34J44 (125 MSPS), ADC34J43 (80 MSPS), and ADC34J42 (50 MSPS). All members share pin compatibility and similar architectural features, allowing for design flexibility across different bandwidth requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADC34J44IRGZ25, ADC34J43IRGZ25, and ADC34J42IRGZ25. These parts offer lower sampling rates but maintain the same 14-bit resolution and package footprint.
