Frequently Asked Questions
What input voltage range does TC7109ACKW accept on its differential analog input channels?
TC7109ACKW accepts a differential analog input voltage from -3.5 V to +3.5 V, covering both positive and negative signal polarities, which is useful for bridge sensor interfaces and precision voltage measurement circuits where bipolar inputs must be resolved to 12-bit accuracy.
How accurate is the TC7109ACKW in terms of linearity, and why does this matter for digital panel meters?
TC7109ACKW achieves a maximum linearity error of 0.024%, meaning the ADC output deviation from an ideal straight-line transfer function is extremely small across the full scale, which is essential for digital panel meters and measurement instruments that display calibrated readings without correction tables.
Why does TC7109ACKW use a dual-slope conversion topology rather than a successive approximation approach?
Dual-slope integration inherently averages out high-frequency noise and rejects power-line interference at 50 Hz or 60 Hz, providing stable 12-bit results even in electrically noisy industrial environments where a successive-approximation ADC would require additional filtering stages.
Is TC7109ACKW still actively manufactured, and what lead time should a procurement engineer plan for?
TC7109ACKW carries a factory lead time of 6 weeks from Microchip, and procurement engineers sourcing it for production builds should include buffer stock in their planning to avoid supply gaps during periods of high industrial ADC demand.
