VOS, IB, and IOS are measured at VCM=0. (2) 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+θjA PD 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. (3) Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice. VS = ±6V to ±15V. 6.6 AC Electrical Characteristics over operating free-air temperature range (unless otherwise noted) LF412A(1) LF412(1) PARAMETER TEST CONDITIONS UNIT MIN TYP MAX MIN TYP MAX Amplifier to TA=25°C, f=1 Hz-20 kHz −120 −120 dB Amplifier Coupling (Input Referred) (1) Unless otherwise specified, the specifications apply over the full temperature range and for VS=±20V for the LF412A and for VS=±15V for the LF412. VOS, IB, and IOS are measured at VCM=0. Copyright © 1999–2014, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Links: LF412-N |
