LM2904D Datasheet | NXP Semiconductors

DESCRIPTION The 532/358/LM2904 consists of two independent, high gain, internally frequency-pensated operational amplifiers internally frequency-pensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage. PIN CONFIGURATIONS D, FE, N Packages OUTPUT A INVERTING INPUT A NON INVERTING INPUT A V- 1 2 3 4 A - + B +- 8 7 6 5 V+ OUTPUT B INVERTING INPUT B NON INVERTING INPUT B UNIQUE FEATURES In the linear mode the input mon-mode voltage range includes ground and the output voltage can also swing to includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage. The unity gain cross frequency is temperature-pensated. The input bias current is also temperature-pensated. Figure 1.
