Note 1 In order to limit maximum junction temperature to a 175 C it may be necessary to operate with VS k g 15V when TA or TC exceeds specific values depending on the PD within the device package Total PD is the sum of quiescent and load-related dissipation Note 2 Specification is at 25 C junction temperature due to requirements of high-speed automatic testing Actual values at operating temperature will exceed the value at TJ e 25 C When supply voltage are g 15V no-load operating junction temperature may rise 40 C – 60 C above ambient and more under load conditions Accordingly VOS may change one to several mV and IB and IOS will change significantly during warm-up Refer to IB and IOS vs temperature graph for expected values Note 3 Measured in still air 7 minutes after application of power

Applications Information
Power Supply Decoupling
The ELH0032 like most high-speed circuits is sensitive to layout and stray capacitance Power supplies should be bypassed as near to pins 10 and 12 as possible with low inductance capacitors such as 0 01 mF disc ceramics Compensation components should also be located close to the appropriate pins to minimize stray reactances
Input Capacitance
The input capacitance to the ELH0032 is typically 5 pF and thus may form a significant time constant with high value resistors For optimum performance the input capacitance to the inverting input should be compensated by a small capacitor across the feedback resistor The value is strongly dependent on layout and closed loop gain but will typically be in the neighborhood of several picofarads In the non-inverting configuration it may be advantageous to bootstrap the case and or a guard conductor to the inverting input This serves both to divert leakage currents away from the non-inverting input and to reduce the effective input capacitance A unity gain follower so treated will have an input capacitance under a 1 pF
Input Current
Because the input devices are FETs the input bias current may be expected to double for each 11 C junction temperature rise This characteristic is plotted in the typical performance characteristics graphs The device will self-heat due to internal power dissipation after application of power thus raising the FET junction temperature 40 C – 60 C above the free-air ambient temperature when supplies are g 15V 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 g 15V All of the effects described here may be minimized by operating the device with VS s g 15V These effects are indicated in the typical performance curves
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
