ADS4149IRGZR

Analog To Digital Converters (ADC) Overview

The ADS4149IRGZR is a single-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a pipeline architecture and supports sampling rates up to 250 MSPS. The device features differential inputs and a parallel digital interface. It functions on dual 1.8 V supplies for analog and digital sections. Key performance metrics include a signal-to-noise ratio of 72.2 dB, an effective number of bits of 11.7, and a spurious-free dynamic range of 80 dB at 100 MHz input frequency. Power consumption is rated at 265 mW. The component is housed in a 48-pin VQFN package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Validate pin compatibility with existing PCB footprints during the procurement phase.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring high resolution and moderate speed with strict power constraints. Compare against the ADS4149EVM development kit for initial validation. Consider the pin-compatible ADS4148 if 12-bit resolution suffices for the application. Evaluate thermal management requirements based on the 265 mW dissipation rating.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS414x family of high-speed, low-power ADCs from Texas Instruments. The family includes variants with different resolutions and sampling rates, such as the ADS4125 and ADS4148. These devices share similar form factors and interface standards, facilitating design scalability across product lines without major hardware revisions.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4149IRGZT is a tray-packaged equivalent of the same functional device. For lower resolution needs, the ADS4148 offers a pin-compatible 12-bit alternative. Verify that any substitute maintains the required 250 MSPS throughput and 14-bit accuracy.
