ADS62P48IRGC25

Analog To Digital Converters (ADC) Overview

The ADS62P48IRGC25 is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 250 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and supports both DDR LVDS and parallel CMOS digital output interfaces. It requires a 3.3 V analog supply and a 3.0 V to 3.6 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 73.9 dB, an effective number of bits (ENOB) of 11.4 bits, and a power dissipation of 660 mW. The component is housed in a VQFN-64 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '25' against the official datasheet to confirm it denotes the industrial temperature grade (-40°C to +85°C) and packaging type. Ensure compatibility with existing board layouts for the VQFN-64 package. Check for moisture sensitivity level requirements during assembly. Confirm availability status as distribution channels may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 12-bit resolution at 250 MSPS is required. Compare SNR and spurious-free dynamic range (SFDR) against alternatives like the ADS62P49 if higher performance is needed. Consider the power budget, as the device dissipates 660 mW. Evaluate the need for DDR LVDS versus parallel CMOS outputs based on downstream FPGA or processor capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS62P48 belongs to the ADS62Pxx family of dual-channel ADCs from Texas Instruments. This series is designed for high-performance applications requiring moderate resolution and high speed. It shares similar pinouts and functionality with other members like the ADS62P42 and ADS62P43, differing primarily in sampling rates and resolution specifications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADS62P49IRGC25 (14-bit, 250 MSPS) for higher resolution or the ADS62P42IRGC25 (12-bit, 80 MSPS) for lower power needs. Cross-family alternatives should be evaluated based on interface compatibility and performance metrics.
