TLC0820A High-Speed 8-Bit Parallel flash ADC, DIP-20

Description

Experience high-speed data conversion with the TLC0820A, a versatile and easy-to-use 8-bit Analog-to-Digital Converter (ADC) designed by Texas Instruments. Perfect for hobbyists and engineers alike, this IC eliminates the need for complex external clocking, making it an ideal choice for DIY data acquisition projects, sensor interfacing, and microprocessor-based systems.

The TLC0820A is an advanced LinCMOS™ 8-bit analog-to-digital converter that utilizes a modified flash technique to achieve high-speed conversions (up to 1.18 µs) without the heavy power consumption of traditional flash converters. It features a built-in track-and-hold circuit with a 100-ns sample window, allowing it to handle fast-moving signals with ease. Designed for simplicity, it interfaces directly with most microprocessors via a parallel bus, appearing just like a memory location or I/O port. Whether you are building a digital oscilloscope or a high-speed sensor hub, the TLC0820A provides a reliable, single 5V solution that requires no external clock components.
