DS4812 General 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

DS4812 Maximum Ratings

Supply Voltage, V_DD (see Note 1)...........................5.5V
Differential Input Voltage (see Note 2)................± V_DD
Input Voltage Range, V_I(see Note 1).........-0.3V to V_DD
Input Current, I_DD.............................................± 4 mA
Output Current, I_O..........................................± 50 mA
Total current into V_DD......................................± 50 mA
Total current out of GND .................................± 50 mA
Duration of short-circuit current (See Note 3) unlimited
Operating Temperature ............................0 to +70
Storage Temperature ..........................-55 to +125
Soldering Temperature....See J-STD-020A Specification
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.
