ADC12D1620LGMLS

Analog To Digital Converters (ADC) Overview

The ADC12D1620LGMLS is a 12-bit, single or dual-channel RF sampling analog-to-digital converter (ADC) from Texas Instruments. It operates at sampling rates up to 3200 MSPS in interleaved mode or 1600 MSPS in dual-channel mode. The device features a 3-GHz input bandwidth and supports low-sampling power-saving mode for clock frequencies at or below 800 MHz. It utilizes a 256-pin CLGA package and is rated for an operating temperature range of -55°C to +125°C. The component is designed for radiation environments with a total ionizing dose tolerance of 300 krad(Si).

Analog To Digital Converters (ADC) Feature Summary

• Radiation hardening with 300 krad(Si) total ionizing dose tolerance and single event latch-up protection exceeding 120 MeV-cm2/mg.
• Supports auto-sync functionality for multi-chip system synchronization and includes a time stamp feature for external trigger capture.
• Features low-sampling power-saving mode that reduces power consumption and improves performance when the clock frequency is 800 MHz or lower.

Analog To Digital Converters (ADC) Applications

• Direct RF down conversion
• Satellite wideband communications
• Synthetic aperture RADAR and LIDAR

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix LGMLS corresponds to the 256-pin CLGA package configuration. Confirm that the flight grade designation matches the required radiation hardness specifications for the intended mission profile. Ensure compatibility with the recommended 3.3-kΩ reference and termination resistors during board design validation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed digitization of RF signals with strict radiation tolerance requirements. Consider the 3-GHz bandwidth and 12-bit resolution for wide dynamic range needs. Evaluate the power consumption benefits of the low-sampling mode if operating at reduced clock speeds below 800 MHz.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12D1620QML family, which includes variants such as the CCGA packaged ADC12D1620CCMLS. The LGMLS variant specifically denotes the CLGA package option within the same functional family, offering improved ENOB, SNR, and crosstalk characteristics compared to its predecessor, the ADC12D1600QML.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12D1620CCMLS serves as a pin-compatible alternative within the same family, differing primarily in the 376-pin CCGA package versus the 256-pin CLGA package. Verify thermal dissipation requirements and footprint compatibility before substitution.
