LM3900 : These devices consist of four independent, highgain frequency-compensated Norton operational amplifiers that were designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies is also possible. The low supply current drain is essentially independent of the magnitude of the supply voltage. These devices provide wide bandwidth and large output voltage swing. The LM2900 is characterized for operation from – 40°C to 85°C, and the LM3900 is characterized for operation from 0°C to 70°C. schematic (each amplifier) SLOS059 – JULY 1979 – REVISED SEPTEMBER 1990 N PACKAGE (TOP VIEW) 1IN + 1 2IN + 2 2IN – 3 2OUT 4 1OUT 5 1IN – 6 GND 7 14 VCC 13 3IN.
