Abstract
CONVERTIDOR DIGITAL/ANALOGICO. CONSTA DE: INVERSORES DE ENTRADA IO-17 QUE ACTUAN COMO CONMUTADORES Y RECIBEN, RESPECTIVAMENTE 2O-27 DE SEÑAL DIGITAL DE ENTRADA; RESISTENCIAS R0-R7 DETERMINATIVAS DE CORRIENTE, PONDERADAS EN BINARIO, QUE ACOPLAN LAS SEÑALES DE SALIDA PROCEDENTES DE LOS INVERSORES A UNA ORDENACION DE DISPOSITIVOS Q0-Q7 DE TRANSISTORES DE SALIDA MOS FET DE ALTA TENSION; LOS DISPOSITIVOS Q0-Q7 TIENEN: LOS ELECTRODOS DE PUERTA CONECTADOS EN COMUN A UN TERMINAL G AL QUE SE APLICA UN POTENCIAL DE POLONIZACION, LOS ELECTRODOS DRENADORES DE SALIDA CONECTADOS EN COMUN A UN TERMINAL DRENADOR D, Y LOS TERMINALES S0-S7 DE ELECTRODO SURTIDOR DE ENTRADA QUE RECIBEN CORRIENTES DE SEÑAL DESDE LAS RESISTENCIAS. SE UTILIZA COMO AMPLIFICADOR DE SALIDA DE VIDEO.
