ADC0804LCV

Analog To Digital Converters (ADC) Overview

The ADC0804LCV is an 8-bit analog-to-digital converter manufactured by National Semiconductor. It features a CMOS architecture designed for microprocessor compatibility. The device operates with a single power supply and includes an internal clock generator, eliminating the need for external timing components. It provides an 8-bit resolution with a typical conversion time of approximately 135 microseconds. The input voltage range is unipolar, typically from 0 to +5V, making it suitable for general-purpose data acquisition applications.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with unipolar input range
• Internal clock generator for simplified design
• Microprocessor compatible parallel output interface
• Single +5V power supply operation

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Portable battery-operated instruments
• General-purpose data acquisition modules

Analog To Digital Converters (ADC) Part Context

The ADC0804LCV belongs to the ADC080x series of 8-bit A/D converters. The 'L' suffix typically denotes a lower power variant or specific temperature grade, while 'CV' indicates a plastic small outline package (SOIC) with a lead-free finish. This component is part of a legacy family widely used in older embedded systems and industrial controllers requiring straightforward analog signal digitization.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include the ADC0804CCN or ADC0804CN from various manufacturers such as Texas Instruments or NXP. When substituting, verify that the replacement maintains the same logic voltage levels and conversion speed requirements. Note that newer SAR ADCs may offer higher resolution but often require different interface protocols like SPI.
