ADC3421IRTQT

Analog To Digital Converters (ADC) Overview

The ADC3421IRTQT is a quad-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It features a pipelined architecture with a sampling rate of 25 MSPS. The device operates on single supply voltages of 1.7V to 1.9V for both analog and digital domains. It utilizes differential inputs and provides serial LVDS data output. 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

• Four independent high-speed analog-to-digital conversion channels
• Integrated synchronous sampling capability across all channels
• Serial low-voltage differential signaling (LVDS) interface for data transmission

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wireless local area network (WLAN) infrastructure
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'QT' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the required operating temperature range aligns with the industrial specifications defined in the official documentation before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized channels are required at 25 MSPS throughput. Compare power consumption metrics against alternative pipeline architectures. Verify that the system clock frequency matches the device's input requirements and that the LVDS receiver logic levels are compatible with the downstream processing circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC342x family of high-performance analog-to-digital converters. The series includes variants with different sampling rates, such as the 50 MSPS ADC3422 and the 80 MSPS ADC3423. All members share similar architectural characteristics and packaging options within the Texas Instruments portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3421IRTQ25 serves as a direct replacement variant within the same package and functional specification. Other family members like the ADC3422 or ADC3423 offer higher sampling rates but require verification of pin compatibility and power budget adjustments.
