XL7135CD – ADC (Analog-to-Digital Converter) – Xinluda

The Xinluda XL7135CD is a 4½-digit, dual-slope integrating analog-to-digital converter with multiplexed BCD outputs and digit drivers, supplied in a SOP-28 package. It is a pin- and function-compatible alternative to the classic ICL7135/TC7135 family.

The Xinluda XL7135CD is a high-precision 4½-digit, dual-slope integrating analog-to-digital converter (ADC) intended for digital panel meters (DPM), digital voltmeters (DVM), and microprocessor-based data-acquisition systems. It combines the well-proven reliability of dual-slope conversion with multiplexed BCD outputs and digit-driver lines, making it a drop-in style alternative to the industry-standard ICL7135 / TC7135 architecture. The XL7135CD is offered in a 28-pin small-outline (SOP-28, 300 mil) package.

Like other devices in the 7135 family, the XL7135CD delivers 4½-digit (20,000-count) resolution with auto-zero and auto-polarity operation, and a set of control lines (STROBE, OVER RANGE, UNDER RANGE, BUSY and RUN/HOLD) that simplify interfacing to microprocessors, UARTs, and external display drivers. Per the manufacturer datasheet, it operates from a 4 V to 6 V supply over a 0°C to +70°C temperature range.
