The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is less. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded 2/9 LF153 - LF253 - LF353 ELECTRICAL CHARACTERISTICS VCC = ±15V, Tamb = +25°C (unless otherwise specified) Symbol Vio DVio Iio Parameter Input Offset Voltage (Rs = 10kΩ) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Input Offset Voltage Drift Input Offset Current- note 1) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Input Bias Current -note 1 Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Large Signal Voltage Gain (RL = 2kΩ, Vo = ±10V) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Supply Voltage Rejection Ratio (RS = 10kΩ) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Supply Current, no load Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Input Common Mode Voltage Range Common Mode Rejection Ratio (RS = 10kΩ) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Output Short-circuit Current Tamb = +25°C Tmin ≤ Tamb ≤ Tmax Output Voltage Swing Tamb = +25°C ±Vopp Tmin ≤ Tamb ≤ Tmax RL = RL = RL = RL = 2kΩ 10kΩ 2kΩ 10kΩ ±11 50 25 80 80 Min.
