SINGLE-SUPPLY DUAL
OPERATIONAL AMPLIFIER
SOP-8
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.
TSSOP-8
FEATURES
*Single Supply

*Low Operating Current: 0.7mA (typ.)
*Slew Rate: 0.5V/μs (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.

APPLICATION
The UTC M2904, in its static state (No in and output condition) when design, QU being biased by constant current
(break down beam) yet, QL stays OFF.
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.
