ADS61B49IRGZR

Analog To Digital Converters (ADC) Overview

The ADS61B49IRGZR is a single-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports a maximum sampling rate of 250 MSPS and features an integrated high-impedance analog input buffer. The device utilizes a pipeline architecture with differential inputs and parallel CMOS/LVDS output interfaces. It operates on a 3.3 V analog supply and a 1.7 V to 1.9 V digital supply. The component is housed in a 48-pin VQFN package rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated high-impedance analog input buffer eliminates the need for external front-end amplifiers.

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Direct RF sampling applications
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the voltage levels match the system design requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC with an integrated input buffer is required. It is suitable for designs needing direct signal acquisition without additional buffering stages, provided the 250 MSPS speed and 14-bit resolution meet the application bandwidth and accuracy needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS61Bx9 family of high-speed ADCs. The series includes variants with different resolutions, such as the 12-bit ADS61B29. The ADS61B49 specifically provides 14-bit performance within this family, sharing the same form factor and core architecture while differing in bit-depth specifications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS61B29 serves as a lower-resolution alternative within the same family. Designers requiring 12-bit performance may consider this substitute if the higher dynamic range of the 14-bit version is not necessary for the specific application.
