| UTC M2904 LINEAR INTEGRATED CIRCUIT SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER DESCRIPTION The UTC M2904 consists of two independent, high gain, internally frequency compensated operation amplifiers which were designed specifically to operate from a single power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. SOP-8 TSSOP-8 FEATURES *Single Supply *Operating Voltage: +3V~+32V *Low Operating Current: 0.7mA (typ.) *Slew Rate: 0.5V/s (typ.) DIP-8 APPLICATIONS *transducer amplifiers, DC gain blocks, and all the conventional op amp circuits which now can be more easily implemented in single power supply systems.

While using with both power source mode, the cross-over distortion might occure instantly when QL ON. There might be cases when application for amplifier of audio signals, not only distortion but also the apparent frequency bandwidth being narrowed remarkably. It is adjustable especially when using both power source mode, constantly to use with higher on QU than the load current (including feedback current),and then connect the pull-down resister RP at the part between output and GND pins.
