DESCRIPTION
The DS4812 BiCMOS dual operational amplifier combines high slew rate and rail-to-rail output swing.
The device provides 10V/
s of slew rate and 6.5 MHz of bandwidth while only consuming 1.5 mA of
supply current per channel. Ideal low voltage BiFET substitute for low gain, high speed applications.

NOTES:
1.
Relative to GND.
2.
Non-inverting input relative to inverting input. Excessive current flows when input is brought below
GND - 0.3V.
3.
The output may be shorted to either supply. Temperature and/or supply voltages must be limited to
ensure that the maximum dissipation rating is not exceeded.
