Frequently Asked Questions
What resolution and linearity does the ICL7135CAI+T provide for voltage measurement?
The ICL7135CAI+T provides 4.5-digit resolution covering counts from 0 to 19999, with a maximum linearity error of 0.005% of full scale. Its dual-slope conversion technique rejects 50 Hz and 60 Hz interference, making it suitable for precision panel meter designs requiring accurate voltage readings in electrically noisy environments.
Can the ICL7135CAI+T directly drive 7-segment display panels without additional driver ICs?
Yes, the ICL7135CAI+T includes an integrated multiplexed display driver that directly controls up to 5 digits of 7-segment LED or LCD displays. This eliminates the need for separate display driver ICs, reducing BOM cost and PCB area in digital voltmeter and panel meter designs operating from ±2 V analog input range.
What analog input range does the ICL7135CAI+T support and how does auto-zero improve accuracy?
The ICL7135CAI+T accepts analog input voltages from -2 V to +2 V with automatic polarity detection. Its built-in auto-zero phase eliminates offset errors before each conversion cycle, ensuring 0.005% linearity across the full input range. This makes the ICL7135CAI+T accurate for precision panel meter applications without requiring external offset trimming.
