ADC32J43IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC32J43IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 80 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 lane speeds up to 3.2 Gbps. It operates on a single 1.8 V supply, consuming approximately 329 mW at maximum sampling rate. Key performance metrics include an SNR of 72.6 dBFS and SFDR of 95 dBc at fIN = 10 MHz. The component is housed in a 48-pin VQFN package measuring 7 mm x 7 mm.

• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '25' against the manufacturer's current documentation to confirm package and tape/reel specifications. Confirm availability status as product lifecycle data may indicate obsolescence or limited production runs. Ensure compatibility with existing board layouts regarding the 48-VQFN exposed pad thermal requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel 14-bit ADC with an integrated JESD204B interface is required for systems operating at sampling rates up to 80 MSPS. Compare against ADC32J42 (50 MSPS) or ADC32J44 (125 MSPS) if speed requirements differ. Verify that the system clock architecture can accommodate the internal PLL multiplication factor of 20 for bit clock generation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC32J4x family, which includes variants with different maximum sampling rates (ADC32J42, ADC32J44, ADC32J45). All members share pin-to-pin compatibility and similar architectural features, differing primarily in their specified maximum ADC clock frequencies and associated AC performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include ADC32J42, ADC32J44, and ADC32J45. Verify that the replacement variant meets the specific sampling rate and dynamic performance requirements of the application.
