ADC32J44IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC32J44IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 125 MSPS with a flexible input clock buffer allowing divide-by-1, -2, or -4 operations. 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. It operates on a single 1.8 V supply, consuming approximately 401 mW at maximum speed. Key performance metrics include a typical SNR of 72.6 dBFS and SFDR of 94 dBc at fIN = 10 MHz. The component is housed in a 48-pin VQFN package measuring 7 mm x 7 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRGZ25' against the manufacturer's official documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with system requirements for JESD204B lane configuration and clocking architecture before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC32J44 variant specifically for applications requiring sampling rates between 50 MSPS and 125 MSPS. For higher speeds up to 160 MSPS, consider the ADC32J45. Verify that the system clock architecture can accommodate the internal divider settings if operating below the maximum supported frequency.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC32J4x family, which includes the ADC32J42, ADC32J43, and ADC32J45. These devices are pin-to-pin compatible with the 12-bit ADC32J2x series, facilitating design upgrades. The family is designed for high-linearity applications requiring large dynamic range and low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC32J45 is a direct functional replacement within the same package if a higher sampling rate of 160 MSPS is required. The ADC32J43 is suitable if a lower sampling rate of 80 MSPS is sufficient. All variants share the same pinout and register map.
