Overview
Description
The TC835 is a low-power, 4-1/2 digit (0.005% resolution) BCD analog-to-digital converter (ADC) characterized for 200 kHz clock rate operation. It operates on a single 5V supply with the TC7660. The multiplexed BCD data output is suitable for interfacing with personal computers. The TC835 supports microprocessor-based data acquisition systems with BUSY and STROBE outputs, along with the RUN/HOLD input. The OVERRANGE, UNDERRANGE, BUSY, and RUN/HOLD control functions, plus multiplexed BCD data outputs, make the TC835 ideal for microprocessor-based scales, measurement systems, and intelligent panel meters. It interfaces with full-function LCD and LED display decoder/drivers.
