ADS5422Y/250

Analog To Digital Converters (ADC) Overview

The ADS5422Y/250 is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 250 MSPS and accepts an input bandwidth up to 175 MHz. The device utilizes a single +3.3V power supply for both analog and digital sections, simplifying system design. It offers differential inputs and provides parallel LVDS outputs for data transfer. Key performance metrics include a typical signal-to-noise ratio (SNR) of 68 dB and a spurious-free dynamic range (SFDR) of 78 dB at Nyquist frequencies. The component is housed in a 48-pin TQFP package suitable for surface-mount applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the ordering information matches the required package type and temperature grade. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between high speed and moderate resolution is required for wideband signal acquisition. Consider the single-supply architecture for power efficiency in portable or space-constrained designs. Evaluate the LVDS output interface requirements against the downstream processing logic levels and trace impedance constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS54xx family of high-performance ADCs from Texas Instruments. The family is characterized by its use of advanced CMOS technology to deliver high linearity and low power consumption. The ADS5422 variant specifically targets applications requiring 12-bit precision at multi-hundred megasample rates, distinguishing it from lower-resolution or slower-speed counterparts in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADS5400 or ADS5420, depending on whether sampling rate or resolution adjustments are needed. Verify pin-to-pin compatibility and electrical parameter overlaps with alternative manufacturers' parts if sourcing flexibility is required.
