ADS5483IRGCR

Analog To Digital Converters (ADC) Overview

The ADS5483IRGCR is a quad-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a pipeline architecture with a sampling rate of 105 MSPS per channel. The device utilizes differential inputs and offers a parallel interface for data output. It operates on a single 3.3 V analog supply and a 3.0 V to 3.6 V digital supply. Key performance metrics include a typical signal-to-noise ratio (SNR) of 73.8 dBFS at a 20 MHz input frequency and an effective number of bits (ENOB) of 11.7 bits. The component is housed in a 64-pin VQFN package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel configuration providing four independent 14-bit ADCs within a single package
• Integrated digital processing capabilities including programmable gain amplifiers and decimation filters
• Flexible power management with multiple low-power modes to optimize energy consumption during idle periods

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems requiring multi-channel signal acquisition
• Medical imaging equipment such as ultrasound scanners
• Test and measurement instruments like oscilloscopes and spectrum analyzers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGCR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the VQFN-64 footprint and thermal pad requirements. Check for any export control classifications or humidity sensitivity levels that may impact storage and handling procedures before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a system requires four synchronized high-speed channels with 14-bit resolution. Compare SNR and spurious-free dynamic range (SFDR) against alternative devices if input frequencies exceed 20 MHz. Consider the integrated digital filter options if post-processing bandwidth reduction is needed to lower data throughput requirements without external FPGA resources.

Analog To Digital Converters (ADC) Part Context

The ADS5483 belongs to the ADS54xx family of high-performance analog-to-digital converters designed for demanding applications. It shares architectural similarities with other quad-channel devices in the series but distinguishes itself through its specific 14-bit resolution and 105 MSPS speed. This places it between lower-resolution, higher-speed models and higher-resolution, slower models in the product lineup.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5263IRGCR is a related quad-channel device offering 16-bit resolution at the same 100 MSPS sampling rate. While pin-compatible, the ADS5263 provides higher precision but may have different power consumption characteristics. Verify interface timing and voltage levels when substituting, as the ADS5263 uses a 1.8 V digital core compared to the ADS5483's 3.0 V to 3.6 V digital supply.
