description

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.

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.

²All 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.

³The 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.
