ADC0820CCN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0820CCN/NOPB is an 8-bit high-speed analog-to-digital converter featuring a built-in track-and-hold function and latched TRI-STATE outputs. Utilizing a half-flash conversion technique with 32 comparators, it achieves a maximum conversion time of 1.5 µs in WR-RD mode and 2.5 µs in RD mode. Operating on a single 5 VDC supply, the device dissipates a maximum of 75 mW. It accepts analog input voltages from 0 V to 5 V without requiring zero or full-scale adjustments. The component interfaces directly with microprocessors via standard logic levels compatible with both MOS and T2L standards.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix /NOPB confirms lead-free compliance and RoHS adherence as per Texas Instruments specifications. Confirm the package type corresponds to the 20-Pin SOIC variant for physical compatibility. Ensure the temperature grade matches the application requirements, as the CCN suffix indicates commercial range operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when interface simplicity is prioritized over absolute minimum power consumption. The built-in sample-and-hold capability allows direct connection to signals with slew rates below 100 mV/µs without external conditioning. Verify that the required resolution fits within the 8-bit constraint and that the 1.5 µs conversion speed meets system timing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0820-N family of 8-bit high-speed A/D converters. The 'CCN' designation specifies the commercial temperature range (-40°C to +85°C) and the 20-Pin SOIC package. The '/NOPB' suffix indicates a non-plumb (lead-free) manufacturing process compliant with environmental directives.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include ADC0820BCN/NOPB for extended temperature ranges or ADC0820CIWM/NOPB for wider operating conditions. Cross-family replacements require careful evaluation of interface timing and voltage level compatibility.
