60 C above the free-air ambient temperature when supplies are g15V The device temperature will stabilize within 5 -10 minutes after application of power and the input bias currents measured at the time will be indicative of normal operating currents An additional rise will occur as power is delivered to a load due to additional internal power dissipation There is an additional effect on input bias current as the input voltage is changed The effect common to all FETs is an avalance-like increase in gate current as the FET gate-to-drain voltage is increased above a critical value depending on FET geometry and doping levels This effect will be noted as the input voltage of the ELH0032 is taken below ground potential when the supplies are g15V All of the effects described here may be minimized by operating the device with VS s g15V Heatsinking While the ELH0032 is specified for operation without any explicit heatsink internal power dissipation does cause a significant temperature rise Improved bias current performance can thus be obtained by limiting this temperature rise with a small heat sink such as the Thermalloy No 2241 or equivalent The case of the device has no internal connection so it may be electrically connected to the sink if this is advantageous Be aware however that this will affect the stray capacitances to all pins and may thus require adjustment of circuit compensation values Burn-In Circuit (Functional Diagram) These effects are indicated in the typical performance curves 0032 -
