LH0032G/CG are 100% production tested as specified at 25oC, Specifications at temperature extremes are verified by testing, periodic characterization, or correlation. Note 2. Specification is at 25oC junction temperature due to requirements of high-speed automatic testing. Actual values at operating temperature will exceed the value at TJ = 25oC. When supply voltages are ±15V, no-load operating junction temperature may rise 40-60oC 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. Guaranteed thru correlated automatic pulse testing. Note 4. Δ VOS /ΔT is the average value calculated from measurements at 25oC and TMAX , specifications at temperature are verified by testing, periodic characterization, or correlation. Note 5. Not 100% production tested; verified by testing, periodic characterization, or correlation. Note 6. Guaranteed by CMRR test condition. Note 7. Guaranteed thru correlated pulse testing at Tj = 25oC.

APPLICATION INFORMATION: Power Supply Decoupling The LH0032, 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 practicable with low inductance capacitors such as 0.01µF disc ceramics. Compensation components should also be located close to the appropriate pins to minimize stray reactances. Input Current Because the input devices are FETs, the input bias current may be expected to double for each 11 oC 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 40-60oC above free-air ambient temperature when supplies are ±15V. The device temperature will stabilize within 5-10 minutes after application of power, and the input bias currents measured at that time will be indicative of normal operating currents. An additional rise would 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 avalanche-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 LH0032 is taken below ground potential when the supplies are ±15V. All of the effects described here may be minimized by operating the device with V S ≤ ±15V. These effects are indicated in the typical performance curves. Input Capacitance The input capacitance to the LH0032/LH0032C is typically 5pF and thus may form a significant time constant with high value resistors.
