ADC3242IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC3242IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 50 MSPS with a single 1.8-V supply. The device features a serial LVDS interface and an internal phase-locked loop for bit clock generation. Key performance metrics include a signal-to-noise ratio of 73.3 dBFS at fIN = 10 MHz and channel isolation of 105 dB. It operates within a temperature range of -40°C to +85°C and is housed in a 48-pin VQFN package measuring 7 mm × 7 mm.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 14-bit resolution with 50 MSPS maximum sampling rate
• Serial LVDS interface reducing pin count and system integration density
• Ultra-low power consumption: 116 mW per channel at 50 MSPS
• Internal dither and chopper for improved linearity

Analog To Digital Converters (ADC) Applications

• Multi-carrier, multi-mode cellular base stations
• Radar and smart antenna arrays
• Software-defined radios (SDRs)
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGZ25' against the manufacturer's current orderable addendum to confirm package type and tape/reel specifications. Check for production status updates as component availability may change. Ensure compatibility with existing board layouts given the 48-VQFN footprint.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3242 variant specifically for systems requiring a 50 MSPS sampling rate. For higher speeds, consider the ADC3243 (80 MSPS) or ADC3244 (125 MSPS). Ensure the input clock frequency and amplitude meet the recommended operating conditions for optimal SNR and SFDR performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC324x family, which includes the ADC3241 (25 MSPS), ADC3243 (80 MSPS), and ADC3244 (125 MSPS). All variants share the same 48-pin VQFN package and pinout, facilitating pin-to-pin compatibility across the family while offering different speed grades.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include ADC3241, ADC3243, and ADC3244 due to identical pinouts. Verify that the alternative sampling rate meets system requirements before substitution.
