Operating Ratings indicate conditions for which the device is func- tional, but do not guarantee specific performance limits. Note 2: For operating at elevated temperature, the device must be derated based on the thermal resistance, θJA. Note 3: Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage. Note 4: These specifications apply for VS=±15V and 0˚C≤TA≤+70˚C. VOS,IB and IOS are measured at VCM=0. Note 5: The input bias currents are junction leakage currents which approximately double for every 10˚C increase in the junction temperature, Tj. Due to the 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+θjA PD where θjA is the thermal resistance from junction to ambient. Use of a heat sink is recom- mended if input bias current is to be kept to a minimum. Note 6: Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice. From ±15V to ±5V. Note 7: 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. 3 www.national.com PrintDate=1998/04/07 PrintTime=13:52:34 38265 ds005648 Rev. No. 3 cmserv Proof 3 |
