... The inputs can be driven beyond the sup- plies without damage or phase reversal of the output. The LT1801 is available in the MS8, SO-8 and the 3mm × 3mm × 0.8mm dual fine pitch leadless package (DFN) with the standard dual op amp pinout. The LT1802 features the standard quad op amp configuration and is available in the 14-pin plastic SO package ...

... • /2) /R DMAX S SMAX S Example: An LT1801 in an SO-8 package operating on ±5V supplies and driving a 50Ω load, the worst-case power dissipation is given by (10 • 4.5mA) + (2.5) /50 = 0.045 + 0.125 DMAX = 0.17W If both amplifiers are loaded simultaneously, then the total power dissipation is 0.34W. ...

... The circuit shown on the first page of this data sheet makes use of the low voltage operation and the wide bandwidth of the LT1801 to create a DC accurate 1MHz 4th order lowpass filter powered from a 3V supply. The amplifiers are configured in the inverting mode for the lowest distor- tion and the output can swing rail-to-rail for maximum dynamic range ...

... U TYPICAL APPLICATIO S Single Supply 1A Laser Driver Amplifier Figure 4 shows the LT1801 used laser driver application. One of the reasons the LT1801 is well suited to this control task is that its 2.3V operation ensures that it will be awaked during power-up and operated before the circuit can otherwise cause significant current to flow in the 2 ...

... R4 and R5. When a transient signal arrives amp output moves and causes the current change depending on the signal polarity. The current, limited by the clipping of the LT1801 output and the 3kΩ of total emitter degeneration, is mirrored to the output devices to drive the capacitive load. The LT1801 output then returns to near mid-supply, providing the precise DC output voltage to the load ...
