ADS5485IRGCTG4

Analog To Digital Converters (ADC) Overview

The ADS5485IRGCTG4 is a 16-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at sampling rates of 170 MSPS or 200 MSPS, depending on the specific variant configuration. The device features a single differential input channel and utilizes an LVDS parallel data interface for high-speed data transfer. It supports both 5-V and 3.3-V supply voltages, offering flexibility in system power design. The component is housed in a 64-pin VQFN package, suitable for space-constrained applications requiring high-resolution signal conversion.

Analog To Digital Converters (ADC) Procurement Notes

Verify the exact datasheet revision and sampling rate specification (170 vs 200 MSPS) as variants exist within the ADS548x family. Confirm that the LVDS interface requirements match the target FPGA or processor inputs. Ensure the PCB layout accommodates the 64VQFN package thermal pad requirements for adequate heat dissipation during continuous high-speed operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution ADC is required with sampling speeds up to 200 MSPS. Consider the ADS5484 if a lower sampling rate of 170 MSPS is sufficient, or if cost optimization is prioritized over maximum speed. Evaluate the power supply compatibility, as the device supports both 5-V and 3.3-V systems, simplifying integration into mixed-voltage environments.

Analog To Digital Converters (ADC) Part Context

The ADS5485 belongs to the ADS548x family of 16-bit ADCs manufactured by Texas Instruments. This family includes the ADS5484 and ADS5485, which share similar architectural features but differ primarily in their maximum sampling rates. The ADS5485 represents the higher-performance variant within this series, designed for applications demanding faster data throughput while maintaining high linearity and resolution.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5484IRGCTG4 is a related part within the same family, offering identical functionality but limited to a 170 MSPS sampling rate. Verify if the reduced speed meets application requirements before substituting. No direct cross-brand replacements are documented in the provided source material.
