ADC1001CCJ

Analog To Digital Converters (ADC) Overview

The ADC1001CCJ is a CMOS, 10-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a 20-pin dual-in-line package and operates within a temperature range of -40°C to +85°C. The device accepts differential analog inputs and utilizes an on-chip clock generator with a typical conversion time of 220 µs at a 410 kHz clock frequency. Data is output via TRI-STATE buffers in two 8-bit bytes, formatted left justified. It requires a single 5V supply and supports ratiometric operation or fixed voltage references.

Analog To Digital Converters (ADC) Feature Summary

• Pin compatible with the ADC0801 series 8-bit A/D converters
• Differential analog voltage inputs for low-frequency common-mode rejection
• On-chip clock generator eliminates external timing components
• TRI-STATE digital outputs compatible with MOS and TTL logic levels

Analog To Digital Converters (ADC) Applications

• Microprocessor systems requiring direct interfacing without additional logic
• Industrial control applications utilizing 5V single-supply operation
• Data acquisition systems needing 10-bit resolution with differential inputs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation when ordering, as the ADC1001CCJ indicates an extended temperature range (-40°C to +85°C), distinct from the commercial grade ADC1001CCJ-1 (0°C to +70°C). Confirm that the application environment remains within the specified operating voltage range of 4.5 VDC to 6.3 VDC to ensure accurate performance and prevent diode conduction errors.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring compatibility with legacy 8-bit microprocessor architectures like the NSC800 or 8080 derivatives. Ensure the analog input voltage does not exceed the supply voltage by more than 50 mV to avoid forward biasing internal protection diodes. Consider the 220 µs typical conversion time when determining system throughput requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1001 family of 10-bit successive approximation converters. It serves as a higher-resolution alternative to the 8-bit ADC0801 while maintaining pin compatibility. The device was originally developed by National Semiconductor and is now supported under the Texas Instruments product portfolio following their acquisition.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC1001CCJ-1 is available as a lower-cost variant with a restricted commercial temperature range of 0°C to +70°C. Designers requiring industrial temperature specifications must use the CCJ suffix. No other direct pin-compatible replacements are documented in the provided datasheet.
