VOS, IB, and IOS are measured at VCM = 0. (2) Refer to RETS442X for LF442-MIL MH military specifications. (3) The input bias currents are junction leakage currents which approximately double for every 10°C increase in the junction temperature, TJ. Due to limited production test time, the input bias currents measured are correlated to junction temperature. In normal operation the junction temperature rises above the ambient temperature as a result of internal power dissipation, PD. TJ = TA + θJAPD where θJA is the thermal resistance from junction to ambient. Use of a heat sink is recommended if input bias current is to be kept to a minimum. (4) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice from ±15 V to ±5 V for the LF442-MIL. 6.5 DC Electrical Characteristics (1) (2) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VOS Input offset voltage RS = 10 kΩ, TA = 25°C 1 5 mV Over temperature 7.5 mV ΔVOS/ΔT Average TC of input offset voltage RS = 10 kΩ 7 μV/°C IOS Input offset voltage VS = ±15 V (1) (3) TJ = 25°C 5 50 pA TJ = 70°C 1.5 nA TJ = 125°C nA IB Input bias current VS = ±15 V (1) (3) TJ = 25°C 10 100 pA TJ = 70°C 3 nA TJ = 125°C nA RIN Input resistance TJ = 25°C 1012 Ω AVOL Large signal voltage gain VS = ±15 V, VO = ±10 V, RL = 10 kΩ, TA = 25°C 25 200 V/mV Over temperature 15 200 V/mV VO Output voltage swing VS = ±15 V, RL = 10 kΩ ±12 ±13 V VCM Input common-mode voltage range ±11 14 V −12 V CMRR Common-mode rejection ratio RS ≤ 10 kΩ 70 95 dB PSRR Supply voltage rejection ratio See(4) 70 90 dB IS Supply current 400 500 μA (1) Unless otherwise specified, the specifications apply over the full temperature range and for VS = ±15 V for the LF442-MIL. VOS, IB, and IOS are measured at VCM = 0. (2) Refer to RETS442X for LF442-MIL MH military specifications. 6.6 AC Electrical Characteristics (1) (2) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Amplifier to amplifier coupling TA = 25°C, f = 1 Hz-20 kHz (Input referred) −120 dB SR Slew rate VS = ±15 V, TA = 25°C 0.6 1 V/μs GBW Gain-bandwidth product VS = ±15 V, TA = 25°C 0.6 1 MHz en Equivalent input noise voltage TA = 25°C, RS = 100 Ω, f = 1 kHz 35 nV/ √Hz in Equivalent input noise current TA = 25°C, f = 1 kHz 0.01 pA/ √Hz |
