ADC0820CCN

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADC0820CCN is an 8-bit CMOS analog-to-digital converter featuring a built-in track-and-hold function and half-flash architecture. It operates on a single 5V supply with a maximum power dissipation of 75 mW. The device provides tri-state latched outputs and requires no external clocking, supporting conversion times of 1.5 µs in WR-RD mode and 2.5 µs in RD mode. Designed for microprocessor compatibility, it accepts logic inputs meeting both MOS and TTL voltage level specifications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCN' indicates the commercial temperature range (0°C to +70°C) and PDIP-20 package. Confirm that the component matches the SNAS529C datasheet revision requirements. Ensure the ordering code corresponds to the exact manufacturer part number before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed conversion without external clocking is required. It is suitable for signals with slew rates below 100 mV/µs. Consider the ±1 LSB total unadjusted error limit for the CCN variant. Verify interface timing requirements against the specified tWR and tRD minimums.

Analog To Digital Converters (ADC) Part Context

The ADC0820-N series utilizes a unique sampled-data comparator design. This architecture allows simultaneous comparison cycles within the MS and LS flash converters, enabling inherent sampling capabilities. The device integrates a most significant 4-bit ADC and a least significant 4-bit ADC to achieve full 8-bit resolution.
