ADC0820CIWMX

Analog To Digital Converters (ADC) Overview

The ADC0820CIWMX is an 8-bit high-speed analog-to-digital converter manufactured by National Semiconductor. It utilizes a half-flash conversion technique to achieve a conversion time of 1.5 µs with a maximum power dissipation of 75 mW. The device integrates a track-and-hold function, eliminating the need for external sampling circuits for signals slewing below 100 mV/µs. It operates on a single 5 VDC supply and features latched tri-state outputs compatible with both MOS and TTL logic levels. The component is housed in a surface-mount package.
