ADS5421Y/RG4

Analog To Digital Converters (ADC) Overview

The ADS5421Y/RG4 is a high-performance, single-channel 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 40 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and features a parallel digital interface for data output. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply between 3 V and 5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 76 dB, an effective number of bits (ENOB) of 12.1, and power dissipation of approximately 925 mW. It is housed in a 64-pin LQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's official documentation to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the exact package type and temperature grade required for the target application environment before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution at 40 MSPS is required for mid-speed applications. Consider the 925 mW power consumption and the need for separate analog and digital power supplies during system design. Verify that the parallel interface timing requirements align with the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS5421 series of high-speed ADCs. It is designed for applications requiring moderate speed and high resolution. The RG4 suffix typically indicates a tape and reel packaging option compliant with specific environmental standards, distinguishing it from tube-packaged variants.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments product selection guide for pin-compatible or functionally equivalent alternatives within the ADS54xx family. Verify that any substitute maintains the same 14-bit resolution, 40 MSPS speed, and LQFP-64 package footprint.
