ADS6244IRGZT

Analog To Digital Converters (ADC) Overview

The ADS6244IRGZT is a dual-channel, 14-bit pipeline analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a maximum sampling rate of 105 MSPS with simultaneous sample-and-hold capabilities for both channels. The device operates on a single 3.3 V supply and utilizes a serial LVDS interface for data output. Housed in a compact 48-pin VQFN package, it supports an operating temperature range from -40°C to +85°C. Key performance metrics include a signal-to-noise ratio of 74.4 dB and an effective number of bits (ENOB) of 11.9 bits at full scale.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture with simultaneous sample-and-hold functionality
• Integrated programmable gain amplifier with coarse and fine adjustment
• Serial LVDS digital output interface for simplified system integration
• Single 3.3 V power supply operation for low voltage compatibility

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Software-defined radio receivers
• Medical imaging equipment
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZT' to confirm the tape-and-reel packaging and industrial temperature grade (-40°C to +85°C). Ensure the order matches the exact part number ADS6244IRGZT to guarantee the 105 MSPS sampling rate variant, as other suffixes may indicate different speed grades or packaging options within the same family.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required alongside high-resolution 14-bit conversion. The integrated PGA reduces external component count compared to discrete solutions. Consider the serial LVDS interface requirements for PCB layout and termination matching. Verify that the 105 MSPS speed meets the Nyquist criteria for the target input bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS624x series of dual-channel ADCs from Texas Instruments. It shares the same 48-VQFN footprint and pinout with variants like the ADS6242 and ADS6243, which offer different sampling rates. This specific model provides a balance between resolution and speed suitable for broadband applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6242IRGZT offers higher sampling speeds (up to 125 MSPS) with identical pinouts. The ADS6243IRGZT provides lower sampling rates (80 MSPS) but maintains the same package and interface. Cross-reference these parts if speed adjustments are acceptable without redesigning the PCB layout.
