TLC7135CN TI Analog-to-Digital Converter | 28-PDIP | 4.5 Digit, ±20000 Counts

Product Overview

The TLC7135CN is a high-performance, 4.5-digit analog-to-digital converter (ADC) from Texas Instruments. It features a dual-slope integration architecture, providing excellent noise rejection and high accuracy. The device is housed in a 28-pin PDIP package, making it suitable for through-hole PCB assembly. With a maximum count of ±20,000, it offers a resolution of 100 µV per count for a 2V full-scale input. The TLC7135CN operates from a single +5V supply and includes an internal clock oscillator, auto-zero, and polarity detection. It is ideal for precision measurement applications such as digital multimeters, panel meters, and industrial process control.
