The ADC0820CCD is a high-speed 8-bit Analog-to-Digital Converter (ADC) manufactured by National Semiconductor (now Texas Instruments). This ADC uses a half-flash conversion technique, enabling it to achieve very fast conversion rates. Its speed and resolution make it well-suited for applications requiring real-time data acquisition and signal processing, such as video processing, high-speed instrumentation, and communication systems.

Technical Specifications

The ADC0820CCD operates from a single 5V supply. It has a typical conversion time of 1.5 µs. The analog input voltage range is 0V to 5V. The digital outputs are TTL compatible. The operating temperature range is 0°C to +70°C. The differential and integral linearity are typically ±1/2 LSB. The total unadjusted error is typically ±1 LSB. The package is typically a ceramic DIP (Dual In-line Package) or a surface-mount package. The device includes an internal voltage reference. The conversion rate can be controlled externally for optimal performance.
