ADS42JB69IRGC25

Analog To Digital Converters (ADC) Overview

The ADS42JB69IRGC25 is a dual-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS with a pipeline architecture and differential input type. The device supports serial CMOS and serial LVDS interfaces, specifically JESD204B for data rates up to 3.125 Gbps. Key performance metrics include a signal-to-noise ratio (SNR) of 75.9 dB, an effective number of bits (ENOB) of 12.1 bits, and a full power bandwidth (FPBW) of 900 MHz. Differential nonlinearity (DNL) is specified at 0.6 LSB, while integral nonlinearity (INL) is 3 LSB. It functions within an ambient temperature range of -40°C to +85°C using a 1.8 V supply.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '25' against official documentation to confirm if it denotes a distinct tape-and-reel quantity or packaging variant compared to standard versions. Confirm current lifecycle status as some sources indicate discontinuation. Ensure compliance with export control regulations if applicable to your region before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring dual-channel synchronization with 16-bit resolution at 250 MSPS. The 900 MHz FPBW makes it suitable for wideband applications. Compare ENOB and SNR requirements against system noise floors. Ensure the PCB layout supports the JESD204B interface constraints and thermal management for the VQFN-64 package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS42JBX9 family of high-performance ADCs. It shares architectural similarities with the ADS42LB69 but features specific interface and power optimizations. The IRGCT suffix typically indicates a cut-tape or reel packaging option within the same functional family, differing primarily in shipping configuration rather than electrical characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS42JB69IRGCT is a direct functional substitute within the same series. For lower resolution needs, the ADS42JB46 offers 14-bit performance at 160 MSPS. Cross-reference pinouts and software configurations when migrating between these variants.
