El ADC0804 es un convertidor analógico a digital de 8 bits con características que lo hacen útil para una variedad de aplicaciones. Este IC puede convertir una entrada analógica en un valor digital de 8 bits, que luego puede ser procesado por un microcontrolador o cualquier otro dispositivo digital.
Aquí están algunos pasos para usar el ADC0804 en tu proyecto:
  1. Proporciona alimentación al chip: El ADC0804 se alimenta con una fuente de tensión de +5V suministrada a los pines 20 (Vcc) y 10 (GND).
  2. Configura la referencia de voltaje: Los pines 9 y 4 son los pines de entrada de referencia de voltaje (VIN(+) y VIN(-)) para la señal analógica. Por lo general, VIN(-) se conecta a tierra y VIN(+) se configura a un voltaje de referencia deseado.
  3. Suministra la señal analógica de entrada: La señal analógica de entrada se aplicará al pin 6 (IN+). El pin 7 (IN-) se conecta a tierra.
  4. Configura el inicio de la conversión (Start of Conversion): Un pulso alto en el pin 3 (START) inicia la conversión de analógico a digital. Este pulso puede ser proporcionado por un microcontrolador u otra fuente de señal digital.
  5. Controla el fin de la conversión (End of Conversion): El ADC0804 ofrece una indicación de cuando la conversión ha finalizado a través del pin 5 (EoC). Este pin se volverá alto al finalizar la conversión y puede ser monitoreado por un microcontrolador.
  6. Lee los datos de salida: Los pines 11 a 18 son las salidas digitales del ADC0804. Estos dan el valor digital de la señal analógica de entrada.
Aquí están las conexiones específicas, asumiendo que estás utilizando un microcontrolador genérico como controlador principal:
  • Conecta MCU:5V a ADC0804:20 (Vcc) y ADC0804:10 (GND).
  • Conecta MCU:GND a ADC0804:4 (VIN-) y ADC0804:7 (IN-).
  • Conecta MCU:ANALOG_INPUT al ADC0806:6 (IN+) y la referencia de voltaje (+5V) a ADC0804:9 (VIN+).
  • Conecta MCU:DIGITAL_OUTPUT a ADC0804:3 (START).
  • Conecta ADC0804:5 (EoC) a MCU:DIGITAL_INPUT.
  • Conecta ADC0804:11-18 (DB0-DB7) a los puertos de entrada del microcontrolador designados para leer los datos del ADC.
Ten en cuenta que estos son solo pasos generales y que el uso específico del ADC0804 puede variar dependiendo del resto de tu circuito y tu programa.
