ADS6243IRGZ25

Analog To Digital Converters (ADC) Overview

The ADS6243 is a dual-channel, 14-bit, 105 MSPS analog-to-digital converter (ADC) designed for high-performance data acquisition systems. It features a differential input architecture with an integrated track-and-hold amplifier and a low-noise, wide-bandwidth front-end buffer. The device supports flexible reference configurations and offers multiple power-down modes to optimize energy efficiency. Key electrical specifications include a full-power bandwidth of 200 MHz, a spurious-free dynamic range (SFDR) of 72 dBc at 10 MHz input frequency, and a typical noise floor of -148 dBm/Hz. The part operates from a single +3.3 V supply and utilizes a 40-lead TQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZ25' against manufacturer documentation to confirm package type and tape-and-reel quantity. Ensure compatibility with existing PCB footprints and thermal management solutions. Confirm that the voltage levels and clocking requirements match the target system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and 14-bit resolution are required at speeds up to 105 MSPS. Evaluate the trade-off between the integrated buffer's power consumption and the need for external driver circuits. Consider the available power-down modes if system-level energy efficiency is a critical design constraint.

Analog To Digital Converters (ADC) Part Context

This device belongs to Texas Instruments' high-speed ADC portfolio, specifically targeting applications needing balanced performance between resolution and speed. It serves as a successor or alternative to older generation parts in similar form factors, offering improved noise performance and integrated signal conditioning compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as other variants in the ADS62xx series. Verify that any substitute maintains the same 14-bit resolution and 105 MSPS sampling rate. Ensure interface compatibility and power supply requirements align with the current design constraints.
