ADC32J42IRGZ25

Analog To Digital Converters (ADC) Overview

The ADC32J42IRGZ25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 50 MSPS and utilizes a JESD204B serial interface. The device features a single 1.8 V supply with typical power consumption of 227 mW per channel at the maximum speed. It includes an internal phase-locked loop (PLL), flexible input clock divider, and support for multichip synchronization via SYSREF. The component is housed in a 48-pin VQFN package measuring 7 mm x 7 mm.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 14-bit resolution with 50 MSPS sampling rate
• JESD204B serial interface supporting up to 3.2 Gbps
• Internal PLL multiplies sampling clock by 20x
• Flexible clock buffer with divide-by-1, -2, or -4 options

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 '25' against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm current production status as product lifecycles may change. Ensure compatibility with system voltage requirements of 1.7 V to 1.9 V for both analog and digital supplies.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 50 MSPS sampling rate is sufficient for the application. Compare against ADC32J43 (80 MSPS) if higher throughput is required. Verify that the JESD204B lane configuration matches the system design constraints. Check thermal dissipation requirements given the 227 mW/ch power consumption at maximum speed.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC32J4x family, which also includes the ADC32J43 (80 MSPS), ADC32J44 (125 MSPS), and ADC32J45 (160 MSPS). All variants share pinout compatibility and similar architectural features, differing primarily in their maximum supported sampling frequencies and associated AC performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include ADC32J43IRGZ25, ADC32J44IRGZ25, and ADC32J45IRGZ25, offering higher sampling rates. For lower-speed applications, the 12-bit ADC32J22 series offers pin-compatible alternatives.
