† 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.
