ADC3441IRTQR

Analog To Digital Converters (ADC) Overview

The ADC3441IRTQR is a quad-channel, 14-bit analog-to-digital converter from Texas Instruments. It operates at a sampling rate of 25 MSPS and features a serial LVDS interface. The device requires a single 1.8 V supply and includes a flexible input clock buffer with divide-by-1, -2, and -4 options. It is housed in a 56-pin VQFN (RTQ) package rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture providing four independent 14-bit conversion paths
• Serial LVDS interface for high-speed data transmission
• Flexible input clock buffer supporting divide-by-1, -2, and -4 configurations
• Single 1.8 V power supply requirement

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wireless local loop infrastructure
• Point-to-point microwave communication links

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTQR' to confirm the 56-pin VQFN package and industrial temperature range (-40°C to +85°C). Ensure the design supports the required 1.8 V single-supply voltage and LVDS signaling standards. Confirm that the target application utilizes the 25 MSPS sampling rate capability rather than higher speeds available in other variants within the ADC344x family.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a multi-channel solution is required for wideband signal acquisition. The integrated clock buffer simplifies timing distribution by allowing internal division ratios. The LVDS interface reduces noise susceptibility in dense PCB layouts. Consider the thermal performance of the RTQ package if high ambient temperatures are expected within the specified operating range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC344x family of quad-channel, 14-bit analog-to-digital converters. While the broader family supports sampling rates up to 125 MSPS, the ADC3441 variant is specifically characterized for 25 MSPS operation. It shares architectural similarities with other members but differs in speed grading and specific electrical characteristics defined by its model number.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC3442, ADC3443, ADC3444, ADC3445, ADC3446, ADC3447, and ADC3448. These parts offer different sampling rates ranging from 25 MSPS to 125 MSPS while maintaining the same pinout and functionality.
