Operating Ratings indicate conditions for which the device is. Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage. Any of the amplifier outputs can be shorted to ground indefinitely, however, more than one should not be simultaneously shorted as the maximum junction.

The value given is in static air. These devices are available in both the commercial temperature range 0? C and the military temperature range ? A “C” indicates the commercial temperature range and an “M” indi. The military temperature range is available in “H” package only.

The input bias currents are junction leakage currents which approximately double for every 10? C increase in the junction temperature, T j. Due to limited pro. In normal operation the junction temperature rises above the ambient tem. Use of a heat sink is recommended.

Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice from. Open Loop Voltage Gain. This device is a dual low power op amp with internally. These JFETs have large reverse breakdown volt. Precautions should be taken to ensure that the power supply. Therefore, large differential input. The maximum differential input volt.

As with most amplifiers, care should be taken with lead. For example, resistors from the output to. Exceeding the negative common-mode limit on either input. In neither case does a latch occur. A feedback pole is created when the feedback around any.

The parallel resistance and capacitance. In many instances the. Exceeding the positive common-mode limit on a single input. However, if the feed.

The amplifiers will operate with a common-mode input volt. The value of the added ca. When the negative common-mode voltage swings to within. Each amplifier is individually biased to allow normal circuit. Battery Powered Strip Chart Preamplifier. Runs from 9v batteries? Fully settable gain and time constant. Battery powered supply allows direct plug-in interface to strip chart recorder without common-mode problems. Trim 1M pot for lf42 kHz full-scale output. No integrator reset FET required.

Mount D1 and D2 in close proximity. High Efficiency Crystal Oven Controller.

A1’s output represents the amplified difference between the LM temperature sensor and the crystal oven’s temperature. A2, a free running duty cycle modulator, drives the LM to complete a servo loop.

Switched mode operation yields high efficiency. Trim 5k for 10? A through ratasheet 5k? Q1, the logging transistor, is thus immune to ambient temperature variation and requires no temperature compensation at all. A critical component is any component of a life.
