description
These devices consist of four independent, high-
gain 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 band-
width 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.

NOTE 3: Clamp transistors are included that prevent the input voltages from swinging below ground more than approximately 0.3 V. The
negative input currents that may result from large signal overdrive with capacitive input coupling must be limited externally to values
of approximately 1 mA. Negative input currents in excess of 4 mA causes the output voltage to drop to a low voltage. These
values apply for any one of the input terminals. If more than one of the input terminals are simultaneously driven negative, maximum
currents are reduced. Common-mode current biasing can be used to prevent negative input voltages.

All characteristics are measured under open-loop conditions with zero common-mode voltage unless otherwise specified. Full range for TA is
40
C to 85
C for LM2900 and 0
C to 70
C for LM3900.
The output current-sink capability can be increased for large-signal conditions by overdriving the inverting input.
NOTE 4: These parameters are measured with the output balanced midway between VCC and GND.
