ADC3421IRTQR

Analog To Digital Converters (ADC) Overview

The ADC3421IRTQR is a quad-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipelined architecture and supports a sampling rate of 25 Msps. The device features four differential analog inputs and provides serial LVDS data output. It operates with analog and digital supply voltages ranging from 1.7V to 1.9V. The component is housed in a 56-pin VQFN package with an exposed thermal pad, designed for surface-mount installation.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent high-speed 12-bit analog-to-digital converters within a single chip.
• Supports simultaneous sampling across all channels for coherent multi-phase signal acquisition.
• Features low-voltage operation compatible with standard digital logic levels via LVDS outputs.

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems requiring multi-channel signal digitization
• Medical imaging equipment such as ultrasound scanners
• Test and measurement instruments including oscilloscopes and spectrum analyzers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm tape-and-reel packaging status. Ensure the part number matches the exact pinout and electrical specifications required for your design, as minor suffix variations can indicate different packaging or temperature grades. Cross-reference the latest datasheet revision to confirm current availability and lifecycle status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a system requires four synchronized 12-bit channels at 25 Msps. It is suitable for designs needing low power consumption and small form factors due to the VQFN package. Consider alternative models if higher sampling rates or resolutions are necessary, or if single-ended input interfaces are preferred over differential configurations.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC342x family of high-speed analog-to-digital converters. The family shares common architectural features but varies in sampling speed and resolution. The ADC3421 specifically targets applications balancing moderate speed with high channel count and precision.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3421IRTQT is a direct functional substitute within the same family, differing primarily in packaging configuration. Verify pin compatibility and thermal performance requirements before substitution.
