ADC0803-1CD

The ADC0803-1CD is an 8-bit CMOS successive approximation Analog to Digital Converter (ADC) family from Philips Semiconductors. These converters are designed for easy integration with microprocessor-controlled buses, requiring minimal external circuitry. The device features differential analog voltage inputs for improved common-mode rejection and a voltage reference input for encoding small analog voltages to the full 8 bits of resolution.

Key features include compatibility with most microprocessors, 3-state outputs that can be directly connected to a data bus, and logic levels compatible with TTL and MOS. The ADC0803-1CD can operate with either an internal or external clock, with guaranteed specifications at a 1 MHz clock frequency. The analog input range is from 0V to VCC, and it operates on a single 5V supply. The device is available in a 20-pin plastic dual in-line package (DIP) and has an operating temperature range of 0°C to 70°C.

Applications for the ADC0803-1CD include transducer-to-microprocessor interfaces, digital thermometers, digitally-controlled thermostats, and microprocessor-based monitoring and control systems. Its design facilitates direct connection to microprocessors, simplifying system design.
