ADC32J45IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC32J45IRGZ25 is a dual-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 compliant with Subclass 0, 1, and 2 standards, supporting data rates up to 3.2 Gbps per lane. Key performance metrics at 160 MSPS include a signal-to-noise ratio (SNR) of 72.5 dBFS and a spurious-free dynamic range (SFDR) of 92 dBc. It operates within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 14-bit resolution with sampling rates up to 160 MSPS
• JESD204B serial interface supporting up to 3.2 Gbps per lane
• Ultralow power consumption: 454 mW typical total dissipation at 160 MSPS
• Internal dither and flexible clock buffer with divide-by-1, -2, or -4 options

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 'IRGZ25' against the manufacturer's official documentation to confirm package type, temperature grade, and reel specifications. Ensure compatibility with system requirements for the 48-pin VQFN form factor and JESD204B interface configuration before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC32J45IRGZ25 when high linearity and low power are required for dual-channel applications operating at sampling frequencies up to 160 MSPS. This model is distinct from the ADC32J42, ADC32J43, and ADC32J44 due to its maximum 160 MSPS speed rating. Verify that the system can support the necessary JESD204B lane count and clocking architecture.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC32J4x family, which includes the ADC32J42, ADC32J43, and ADC32J44. These devices share pin-to-pin compatibility and similar architectural features but differ primarily in their maximum supported sampling rates, ranging from 50 MSPS to 160 MSPS.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC32J42, ADC32J43, and ADC32J44 are pin-compatible members of the same family. However, they offer lower maximum sampling rates (50 MSPS, 80 MSPS, and 125 MSPS respectively). No other direct substitutes are documented in the provided source material.
