ADC0816CCJ

Updated: 2026-09-16

Overview

The ADC0816CCJ is a high-performance 8-bit analog-to-digital converter manufactured using CMOS technology. It features a 16-channel multiplexer, allowing it to handle multiple analog inputs with a single conversion unit. This component is widely used in industrial automation, instrumentation, and embedded systems where reliable analog signal digitization is required. The device operates on a single +5V power supply, making it compatible with most standard digital logic circuits. Its conversion time of approximately 100μs makes it suitable for moderate-speed applications, while its built-in track-and-hold function ensures accurate sampling of analog signals.

Structure and Working Principle

The ADC0816CCJ consists of three main functional blocks: a 16-channel analog multiplexer, an 8-bit successive approximation ADC, and digital control logic. The multiplexer selects one of 16 analog input channels, which is then fed to the ADC core for conversion. The successive approximation register (SAR) architecture provides a balance between speed and accuracy. During operation, the device uses a capacitor array and comparator to perform binary search conversion. The conversion process begins with a start command, after which the SAR determines each bit of the digital output sequentially. The end-of-conversion (EOC) signal indicates when valid data is available at the output pins.

Key Features

The ADC0816CCJ offers several notable features including a wide analog input voltage range (typically 0-5V), low power consumption (approximately 15mW), and compatibility with microprocessor interfaces. Its 16-channel input multiplexer eliminates the need for external switching components in multi-signal applications. Additional features include a built-in voltage reference, three-state output capability for bus compatibility, and an adjustable conversion rate. The device's CMOS construction provides good noise immunity and allows for operation across a temperature range of 0°C to 70°C, making it suitable for commercial and industrial environments.

Application Areas

This converter is commonly employed in process control systems, data acquisition units, and industrial measurement equipment. Its ability to handle multiple analog inputs makes it particularly useful in monitoring applications where several sensors need to be read sequentially. Other applications include medical instrumentation, automotive systems, and consumer electronics. In embedded systems, the ADC0816CCJ is often used to interface analog sensors (temperature, pressure, light) with digital microcontrollers. Its moderate speed and resolution make it ideal for applications that don't require high-speed or high-precision conversion.

Maintenance and Precautions

To ensure optimal performance, proper grounding and power supply decoupling are essential. Bypass capacitors (typically 0.1μF ceramic) should be placed close to the power pins. Analog inputs should be protected from noise and voltage spikes, potentially requiring RC filters or clamping diodes. When designing with this ADC, pay attention to the analog input impedance requirements and ensure signal sources can drive the input capacitance. The device should be operated within its specified voltage and temperature ranges. Electrostatic discharge (ESD) precautions should be observed during handling and installation.

B2B Procurement Guide

When procuring ADC0816CCJ converters, verify the manufacturer's authenticity as counterfeit components can be a concern in the semiconductor market. Consider purchasing from authorized distributors or reputable electronic component suppliers. For production quantities, check lead times and minimum order quantities. Some suppliers may offer price breaks at certain quantity thresholds. Evaluate whether the PDIP (plastic dual in-line package) version meets your needs or if alternative packaging options are required. Don't forget to account for any necessary support components like voltage references or interface logic in your procurement planning.
