TLC1542 11 Channel, 10-Bit Analog-to-Digital Converter (ADC), DIP-20

Description

Upgrade your DIY projects with the TLC1542, a high-performance 10-bit Analog-to-Digital Converter designed for hobbyists who need more than just a basic sensor reading. This IC offers 11 analog input channels, allowing you to monitor a massive array of sensors—from temperature and light to potentiometers—using just a few pins on your Arduino or ESP32 thanks to its efficient serial interface. Housed in a beginner-friendly 20-pin Through-Hole (DIP) package, it plugs directly into your breadboard or perfboard without the need for difficult surface-mount soldering. With built-in sample-and-hold and a fast 21-µs conversion time, the TLC1542 ensures your data is accurate and responsive, making it a must-have for advanced data logging and robotics.
