ADC3241IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC3241IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 25 MSPS and operates on a single 1.8-V supply. The device features a serial LVDS interface to reduce pin count and includes an internal phase-locked loop for bit clock generation. Key performance metrics include an SNR of 72.4 dBFS and SFDR of 87 dBc at fIN = 70 MHz. It offers ultra-low power consumption of 116 mW per channel at maximum speed and provides 105 dB channel isolation.

• 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 availability status. Ensure the design accommodates the VQFN-48 thermal requirements, as junction-to-ambient resistance is 25.7 °C/W. Confirm that the 25 MSPS sampling rate meets system bandwidth needs, as higher-speed variants exist within the family.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3241 specifically for applications requiring a maximum sampling rate of 25 MSPS. For higher throughput, consider the ADC3242 (50 MSPS), ADC3243 (80 MSPS), or ADC3244 (125 MSPS). All variants share the same pinout and register map, ensuring pin-to-pin compatibility within the 14-bit serial LVDS family. Verify analog input bandwidth requirements, as the device supports frequencies up to 540 MHz.

Analog To Digital Converters (ADC) Part Context

The ADC3241 belongs to the ADC324x family, which also includes the ADC3242, ADC3243, and ADC3244. These devices are designed for high-linearity, low-power applications. The family utilizes a common VQFN-48 package and serial LVDS interface. The ADC3241 represents the entry-level sampling speed in this specific 14-bit pipeline configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include ADC3242, ADC3243, and ADC3244, offering higher sampling rates. For 12-bit resolution alternatives, the ADC322x series is compatible. No external substitutes are documented; verify obsolescence status through official channels.
