Clarifying Questions (5 mins)

• Looking at the industrial context, I'm thinking about the specific types of applications where these ADCs are most commonly used. Could you provide more information about the primary industrial use cases for these converters?

Why it matters: Determines the focus areas for optimization and potential trade-offs. Expected answer: Factory automation, process control, and power management systems. Impact on approach: Would tailor solutions to specific industrial requirements and constraints.

• Considering the energy efficiency goal, I'm curious about the current power consumption benchmarks. What are the typical power consumption levels for TI's ADCs in industrial applications, and how do they compare to competitors?

Why it matters: Establishes a baseline for improvement and identifies competitive gaps. Expected answer: TI's ADCs consume X mW in standby and Y mW during conversion, slightly higher than leading competitors. Impact on approach: Would focus on specific power-saving techniques to close the gap or surpass competitors.

• Given the industrial setting, I'm thinking about environmental factors that might affect ADC performance. What are the most challenging operating conditions these ADCs face in industrial environments?

Why it matters: Helps identify potential areas where energy efficiency improvements might be constrained by environmental factors. Expected answer: High temperatures, electromagnetic interference, and vibration. Impact on approach: Would consider solutions that balance energy efficiency with robustness and reliability.

• Considering the product lifecycle, I'm wondering about the current generation of TI's industrial ADCs. How long has the current product line been in the market, and what have been the most significant customer requests for improvement?

Why it matters: Determines if we're looking at incremental improvements or a more substantial redesign. Expected answer: Current generation is 3-4 years old, with customers requesting lower power consumption and higher sampling rates. Impact on approach: Would focus on balancing these potentially conflicting requirements in the proposed solutions.
