ADS61B49IRGZT

Analog To Digital Converters (ADC) Overview

The ADS61B49IRGZT is a single-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 210 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and supports both parallel CMOS and DDR LVDS digital output interfaces. Power requirements include a 3.3 V analog supply and a 1.7 V to 1.9 V digital supply. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.9 dB, an Effective Number of Bits (ENOB) of 11.4 bits, and a power dissipation of approximately 628 mW. It is housed in a VQFN-48 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports dual-mode digital outputs for flexible interface compatibility with parallel CMOS and DDR LVDS standards.
• Delivers high dynamic performance with low power consumption suitable for bandwidth-constrained applications.
• Integrates a pipeline architecture optimized for wideband signal processing.

Analog To Digital Converters (ADC) Applications

• Wireless infrastructure base stations
• Test and measurement instrumentation
• Software-defined radio systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the exact part number against official Texas Instruments documentation, as standard listings typically reference ADS6149 or ADS6128 variants. Confirm that the suffix 'B' does not indicate a specific binning or revision code that alters electrical specifications. Ensure the VQFN-48 package type matches the design footprint requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel 12-bit resolution at 210 MSPS is required. Compare SNR and power dissipation against alternatives like the ADS6128 if lower power is critical. Verify that the available parallel CMOS or LVDS output modes align with the downstream FPGA or processor interface capabilities.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS61xx family of high-speed ADCs from Texas Instruments. It shares architectural similarities with the ADS6149 but offers 12-bit resolution instead of 14-bit. The family is designed for applications requiring a balance between sampling speed, resolution, and power efficiency in compact surface-mount packages.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6128IRGZT is a verified single-channel substitute within the same family offering identical 12-bit resolution and 210 MSPS performance. The ADS6149IRGZT serves as a higher-resolution alternative with 14-bit capability at the same sampling rate.
