ADC0820CCWMX

Analog To Digital Converters (ADC) Overview

The ADC0820CCWMX is an 8-bit high-speed analog-to-digital converter manufactured by Texas Instruments. It utilizes a half-flash conversion technique to achieve a maximum conversion time of 1.5 µs in WR-RD mode and 2.5 µs in RD mode. The device operates on a single 5 V supply with a maximum power dissipation of 75 mW. It features a built-in track-and-hold function, eliminating the need for external sample-and-hold circuits for signals with slew rates below 100 mV/µs. The component provides latched tri-state outputs and logic inputs compatible with both MOS and TTL voltage levels.

Analog To Digital Converters (ADC) Feature Summary

• Half-flash architecture with 32 comparators for 1.5 µs (WR-RD) or 2.5 µs (RD) conversion times
• Built-in track-and-hold function suitable for input signals slewing at less than 100 mV/µs
• Latched tri-state digital outputs with MOS and TTL voltage level compatibility
• Single 5 VDC supply operation with low power consumption of 75 mW maximum

Analog To Digital Converters (ADC) Applications

• Microprocessor-based monitoring and control systems
• Transducer to microprocessor interfaces
• Process control applications
• Logic analyzers and test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. The 'CCWM' designation indicates a SOIC-20 package with commercial operating temperature specifications. Confirm that the NOPB suffix is present if lead-free compliance is required. Ensure the source documentation explicitly lists the full part number to avoid confusion with similar variants.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and high-speed conversion are required without external sampling hardware. It is suitable for interfacing directly with microprocessors due to its memory-mapped interface capability. Consider the WR-RD mode for faster throughput or RD mode for simpler timing. Verify that the analog input signal slew rate remains within the 100 mV/µs limit to maintain accuracy without additional circuitry.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC0820 series of CMOS A/D converters. It is designed to appear as a memory location or I/O port, simplifying system integration. The half-flash technique distinguishes it from standard successive approximation register (SAR) converters by offering faster conversion speeds while maintaining low power consumption.
