ADC1175-50CILQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC1175-50CILQ/NOPB is a high-speed, low-power 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 50 MSPS with an input bandwidth of 130 MHz. The device features a differential input architecture and utilizes a single +3.3 V supply voltage. Key electrical specifications include a typical signal-to-noise ratio (SNR) of 64 dB and a total harmonic distortion (THD) of -72 dBc. It is housed in a 48-pin LFCSP package and supports operation over an extended industrial temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a track-and-hold amplifier and reference for simplified system design

• Features low power consumption suitable for battery-operated applications

Analog To Digital Converters (ADC) Applications

• Medical imaging systems
• Industrial process control
• Communications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance as per manufacturer documentation. Confirm the 'LQ' designation indicates the qualified automotive or extended temperature grade if required by the application environment. Ensure the 48-pin LFCSP footprint matches the PCB layout specifications exactly to avoid assembly issues.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 50 MSPS throughput are required within a compact form factor. Compare SNR and THD performance against alternative ADCs in the same speed class to ensure signal integrity requirements are met. Verify that the single 3.3 V supply capability aligns with the system's power budget and voltage domain constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC117x family of high-speed data converters designed for demanding signal processing tasks. It serves as a bridge between analog sensor signals and digital processing units like FPGAs or DSPs. The NOPB suffix denotes a non-pb (lead-free) version compliant with environmental standards, replacing older leaded variants in the product line.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the ADC117x series offering higher speeds or resolutions. Evaluate alternative 12-bit, 50 MSPS ADCs from other manufacturers if supply constraints exist, ensuring interface compatibility and power specifications match.
