Note 1

Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage

Note 2

For operating at elevated temperature these devices must be derated based on a thermal resistance of ijA

Note 3

The temperature range is designated by the position just before the package type in the device number A ‘‘C’’ indicates the commercial temperature range

and an ‘‘M’’ indicates the military temperature range The military temperature range is available in ‘‘H’’ package only

Note 4

Unless otherwise specified the specifications apply over the full temperature range and for VS e g20V for the LF441A and for VS e g15V for the LF441

VOS IB and IOS are measured at VCM e 0

Note 5

The LF441A is 100% tested to this specification

Note 6

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 e TA a ijA PD where ijA 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

Note 7

Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice From

15V to g5V for the LF441 and from g20V to g5V for the LF441A

Note 8

Refer to RETS441X for LF441MH military specifications

Note 9

Max Power Dissipation is defined by the package characteristics Operating the part near the Max Power Dissipation may cause the part to operate

outside guaranteed limits
