ADC0804LCN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0804LCN/NOPB is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates on a single 5-V supply and features differential analog voltage inputs for improved common-mode rejection. The device includes an on-chip clock generator, tri-state output latches, and logic compatible with both MOS and TTL voltage levels. Designed for microprocessor interfacing without additional logic, it offers a conversion time of approximately 100 µs at a 640 kHz clock frequency. The component is housed in a standard 20-pin Dual-In-Line (PDIP) package.
