TBA673 RING (DE)MODULATOR

TBA673 II II RING (DE)MODULATOR FOR TELEPHONY AND INDUSTRIAL EQUIPMENT The TBA673 is a monolithic integrated circuit comprising a 4-transistor modulator and demodulator circuit. The four transistors must be as identical as possible; the lay-out has been designed to achieve this and the best possible tracking of the transistor parameters with tempera ture. QUICK REFERENCE DATA Collector cut -off current IE = 0; VCB = 5 V; Tamb = 25 °c Base-emitter voltage differences between transistors 1, 2,.
