Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS6444IRGC25 is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 14-bit resolution at 105 MSPS
• Channel Configuration: 4 differential input channels with simultaneous sampling
• Signal Interface: LVDS serial data output
• Converter Architecture: Pipelined topology
• Power Supply Requirements: 3V to 3.6V for both analog and digital supplies
• Package and Pinout: 64-VQFN (9x9) with exposed pad
• Temperature Rating: -40°C to 85°C operating range

The ADS6444IRGCT meets all these parameters identically to the main part, establishing it as a parametric equivalent. The primary distinction between these parts is product status: the ADS6444IRGC25 is obsolete, while the ADS6444IRGCT is active in production.
