ADC31JB68RTAT

Analog To Digital Converters (ADC) Overview

The ADC31JB68RTAT is a dual-channel, high-speed analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 640 MSPS with a 16-bit resolution. The device utilizes JESD204B interface technology for digital data output. It supports multiple analog supply voltage options including 1.8 V and 3.3 V, alongside a digital I/O supply range of 1.7 V to 1.95 V. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 70.3 dB and an Spurious-Free Dynamic Range (SFDR) of 80 dB at Nyquist. The component is housed in a 196-ball NFBGA package and functions within an industrial temperature range from -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with required JESD204B link layer settings during system integration. Cross-reference pin assignments with official mechanical drawings before PCB layout finalization.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and high linearity are required at 640 MSPS. Evaluate power consumption constraints relative to the 1.8 V and 3.3 V supply options. Consider the NFBGA-196 footprint requirements and thermal management needs for the specified operating temperature range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC31JBxx family of dual-channel converters designed for demanding RF applications. It shares architectural similarities with other high-speed TI ADCs but offers specific integration benefits such as built-in digital correction capabilities. The RTAT suffix denotes the specific reel packaging and temperature rating configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements may include other members of the ADC31JBxx series with adjusted sampling rates or channel counts. Verify electrical compatibility and pinout alignment before substituting with single-channel high-speed ADCs requiring additional external circuitry.
