ADC0816CCJ

Analog To Digital Converters (ADC) Overview

The ADC0816CCJ is an 8-bit analog-to-digital converter manufactured by National Semiconductor, now part of Texas Instruments. It features a built-in 16-channel multiplexer for selecting single-ended analog inputs. The device operates on a single +5V supply and utilizes a successive approximation architecture with a typical conversion time of approximately 100 microseconds. Digital outputs are TTL/CMOS compatible, facilitating direct interfacing with microprocessors. The component is housed in a 28-lead plastic DIP package and is specified for operation within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-based data logging applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'CCJ' corresponds to the 28-lead DIP package and industrial temperature grade. Check current product status, as legacy components may be discontinued or subject to last-time-buy notices from the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 8-bit resolution and 16 input channels are required without external multiplexers. Ensure the system voltage matches the +5V requirement. Consider the 100µs conversion speed against application timing constraints. Verify that the parallel interface aligns with the target microprocessor's I/O capabilities.

Analog To Digital Converters (ADC) Part Context

The ADC0816 belongs to the National Semiconductor ADC08xx family of microprocessor-compatible A/D converters. It extends the functionality of the 8-channel ADC0808/0809 by integrating a 16-channel multiplexer. This series is designed for cost-effective, low-speed data acquisition tasks where high precision is not critical.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-for-pin replacements may be limited due to the specific 16-channel integration. Alternatives such as the ADC0820 require external multiplexing. Verify compatibility with existing PCB footprints and logic levels when substituting with modern equivalents.
