ADS6149IRGZR

Analog To Digital Converters (ADC) Overview

The ADS6149IRGZR is a single-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments, operating at a maximum sampling rate of 250 MSPS. It features a compact 48-lead QFN package and consumes 687 mW total power dissipation at full speed. The device supports both Double Data Rate (DDR) LVDS and parallel CMOS digital output interfaces. Key electrical characteristics include a typical Signal-to-Noise Ratio (SNR) of 73.4 dBFS at 20 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 92 dBc under the same conditions. It operates with an analog supply voltage of 3.3 V and a digital supply voltage of 1.8 V.

Analog To Digital Converters (ADC) Feature Summary

• Maximum sampling rate of 250 MSPS with 14-bit resolution in a 48-QFN package.
• Total power dissipation of 687 mW at 250 MSPS, scaling down automatically at lower rates.
• Dual output interface options: DDR LVDS and Parallel CMOS.
• Programmable fine gain up to 6 dB for SNR/SFDR trade-off optimization.

Analog To Digital Converters (ADC) Applications

• Multicarrier, wide-bandwidth communications
• Software Defined Radio
• Power Amplifier Linearization
• Test and Measurement Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'RGZR' corresponds to the tape and reel packaging format as specified in the manufacturer's ordering information. Confirm the industrial temperature range specification of -40°C to 85°C matches the application requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and adherence to production data specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS6149IRGZR when a high-speed, low-power 14-bit ADC is required for wideband applications. Choose this part over the ADS6148 if the design requires the higher 250 MSPS sampling rate instead of 210 MSPS. Consider the available DDR LVDS or parallel CMOS outputs based on the downstream FPGA or processor interface capabilities. Verify that the 3.3 V analog and 1.8 V digital supply voltages align with the system power architecture.

Analog To Digital Converters (ADC) Part Context

The ADS6149 belongs to the ADS614X family of 14-bit ADCs, which are pin-compatible with the ADS612X family of 12-bit devices. This family is designed to combine high dynamic performance with low power consumption. The device is specified over the industrial temperature range and is suitable for applications demanding efficient signal chain integration in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6148 serves as a lower-speed alternative within the same family, offering 210 MSPS sampling. For pin-compatible upgrades or downgrades, the ADS6129 (12-bit, 250 MSPS) and ADS6128 (12-bit, 210 MSPS) are also available in the same package.
