UTC324 QUAD OPERATIONAL AMPLIFIERS DESCRIPTION LINEAR INTEGRATED CIRCUIT The UTC324 consists of four independent, high gain internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. Operation from split power supplies is also possible so long as the difference between the two supplies 3 Volts to 32 volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP amp circuits which now can be easily implemented in single power supply system. FEATURES *Internally frequency compensated for unity gain *Large DC voltage gain :100dB *Wide operating supply range(Vcc=3V~32V) *Input common-mode voltage includes ground *Large output voltage swing: F [ ... ]
