ADC3441IRTQ25

Analog To Digital Converters (ADC) Overview

The ADC3441IRTQ25 is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates from 25 MSPS to 125 MSPS with a single 1.8-V supply. The device features a serial LVDS interface and an internal phase-locked loop (PLL) for bit clock generation. Key performance metrics include a signal-to-noise ratio (SNR) of 72.4 dBFS at fIN = 70 MHz and spurious-free dynamic range (SFDR) of 87 dBc. It operates within a temperature range of -40°C to +85°C and is housed in a VQFN-56 package.

• Serial LVDS interface reducing pin count
• Internal PLL and support for multi-chip synchronization via SYSREF

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 'IRTQ25' against the manufacturer's current orderable addendum to confirm package type and tape/reel specifications. Check for any recent product change notices (PCN) regarding availability or material composition updates before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low power consumption are required for multi-channel applications. Ensure the system clock architecture accommodates the internal PLL and that the serial LVDS interface matches the downstream receiver capabilities. Verify that the 1.8-V supply voltage aligns with the system power design.

Analog To Digital Converters (ADC) Part Context

The ADC3441 is part of the ADC344x family, which includes variants with different maximum sampling rates (ADC3442: 50 MSPS, ADC3443: 80 MSPS, ADC3444: 125 MSPS). All devices share the same 14-bit resolution, quad-channel architecture, and VQFN-56 package, offering pin-to-pin compatibility within the series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include ADC3442IRTQ25, ADC3443IRTQ25, and ADC3444IRTQ25, depending on the required sampling rate. For lower resolution needs, the 12-bit ADC342x series offers pin-compatible options.
