ADS42LB49IRGCT

Analog To Digital Converters (ADC) Overview

The ADS42LB49IRGCT is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and provides digital outputs via serial CMOS and serial LVDS interfaces. It functions on a single 1.8 V supply voltage for both analog and digital sections. Key performance metrics include a signal-to-noise ratio (SNR) of 75.8 dB and an effective number of bits (ENOB) of 12.2 bits. The component is housed in a 64-pin VQFN package with exposed pad and supports an industrial operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCT to confirm the tape-and-reel packaging format and industrial temperature grade. Ensure compatibility with the required serial interface configuration during procurement planning. Confirm RoHS compliance status through official manufacturer documentation prior to ordering. Validate that the supplier source is authorized to guarantee part authenticity and traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a balance between high resolution and moderate power consumption is required. The 14-bit resolution suits applications needing better linearity than 12-bit devices but lower power than 16-bit alternatives. Consider the serial interface complexity versus parallel throughput needs. Evaluate system bandwidth requirements against the 250 MSPS sampling limit to ensure adequate Nyquist zone coverage.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS42LBxx family of low-power, high-performance ADCs. It shares the same physical footprint and pinout with the 16-bit ADS42LB69 variant, facilitating board-level upgrades. The series targets multi-standard wireless infrastructure where power efficiency and spectral purity are critical constraints for dense deployment scenarios.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS42LB69IRGCT serves as a higher-resolution alternative within the same package. Verify interface timing compatibility when substituting models. Check if the application requires the specific 14-bit ENOB characteristics rather than the 16-bit version's performance profile.
