ADC3243IRGZT

Analog To Digital Converters (ADC) Overview

The ADC3243IRGZT is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a maximum sampling rate of 50 MSPS and utilizes a pipeline architecture. The device features serial LVDS output interfaces and supports both external and internal reference modes. Key performance metrics include an Effective Number of Bits (ENOB) of 12 bits, a Spurious-Free Dynamic Range (SFDR) of 93 dB, and a Signal-to-Noise and Distortion Ratio (SINAD) of 73.9 dB. Typical power consumption is 120 mW. It functions within an operating temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling capability for coherent signal processing
• Low power consumption design suitable for battery-operated systems
• Integrated low-noise programmable gain amplifier for flexible input ranges
• Serial LVDS interface for high-speed data transmission with reduced pin count

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR)
• Wireless Local Loop (WLL) base stations
• Point-to-point microwave radio links
• Medical imaging equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRGZT' to confirm the industrial temperature rating (-40°C to +85°C) and tape-and-reel packaging format. Ensure compatibility with the required voltage levels for the serial LVDS interface. Check for moisture sensitivity level (MSL) requirements during storage and handling to prevent damage before reflow soldering.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required at moderate speeds up to 50 MSPS. Compare against the ADC3241 (25 MSPS) if lower speed suffices, or the ADC3244 (125 MSPS) if higher bandwidth is needed. Consider the integrated PGA and reference options to simplify external circuitry compared to discrete solutions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC324x family of high-performance, low-power, dual-channel 14-bit ADCs from Texas Instruments. It shares architectural similarities with the ADC3241, ADC3242, and ADC3244, differing primarily in sampling rates and specific feature sets like the presence of an on-chip reference or PGA.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC3241IRGZT, ADC3242IRGZT, and ADC3244IRGZT. Verify that the alternative's sampling rate and feature set (such as PGA availability) meet the original design requirements.
