... U U APPLICATIO S I FOR ATIO Circuit Description The LT1803/LT1804/LT1805 have input and output signal ranges from the negative power supply to the positive power supply. Figure 1 depicts a simplified schematic of one amplifier. The input stage is comprised of two differ- ential amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/ Q4 that are active over the different ranges of the common mode input voltage ...

... Output JA is significantly JA The LT1803/LT1804/LT1805 can deliver a large output current, so the short-circuit current limit is set around 50mA to prevent damage to the device. Attention must be paid to keep the junction temperature of the IC below the absolute maximum rating of 150 C (refer to the Power Dissipation section) when the output is continuously short circuited ...

... When feedback resistors are used to set up gain, care must be taken to ensure that the pole formed by the feedback resistors and the total capacitance at the inverting input does not degrade stability. For instance, the LT1803/ LT1804/LT1805 in a noninverting gain of 2 setup with two 5k resistors and a capacitance of 5pF (part plus PC board) will probably oscillate ...
