Frequently Asked Questions
What is the full-scale analog input voltage range of the TC7117ACKW and how many display digits does it support?
The TC7117ACKW accepts a full-scale analog input from 2.7 V to 3.35 V and drives a 3.5-digit LED display, giving a maximum reading of 1999 counts. The dual-slope ADC architecture provides excellent 50 Hz and 60 Hz noise rejection for stable readout in AC-powered environments.
Which measurement instrument designs benefit from using the TC7117ACKW dual-slope converter?
Digital panel meters, benchtop multimeters, and industrial process indicators benefit most from the TC7117ACKW because its dual-slope conversion suppresses mains-frequency interference. The IC drives LED segments directly at up to 3.35 V analog input, reducing component count in 3.5-digit measurement applications that require reliable readings in factory or laboratory settings.
How many analog input channels does the TC7117ACKW have and what package does it use?
The TC7117ACKW features 1 analog input channel and is packaged in a 44-pin MQFP (JEDEC S-PQFP-G44) surface-mount package with a standard quad flat-pack footprint. This package provides adequate pin count for segment drive outputs and reference connections while keeping PCB area requirements reasonable for compact instrument designs.
What is the typical lead time for TC7117ACKW and how does its RoHS status affect procurement?
The TC7117ACKW has a factory lead time of approximately 6 weeks and carries a RoHS-compliant e3 (Pb-free) rating, making it compatible with lead-free soldering processes. The e3 JESD-609 code indicates the device meets MSL moisture sensitivity requirements for standard surface-mount assembly without special handling beyond the rated floor life.
