LH740A

The LH740A is designed as one kind of FET input, general purpose operational amplifier with high input impedance, closely matched input characteristics, and good slew rates. Input offset voltage is typically 10.0 mV at 25, while input bias current is less than 100 pA at 25. Offset current is typically less than 40 pA at 25.

Features of the LH740A are:(1)internal 6 dB.octave frequency compensation;(2)unity gain slew rate in excess of 6 V/us;(3)unity gain bandwidth of 1 MHz;(4)input offset is adjustable with a single 10k pot;(5)pin cpmpatible with LM741;(6)excellent offset current match over temperature, typically 100 pA;(7)output is continuously short-circuit proof;(8)excellent open loop gain, typically in excess of 100 dB;(9)guaranteed over the full military temperature range.

The absolute maximum ratings of the LH740A can be summarized as:(1)supply voltage: +/-22 V;(2)maximum power dissipation: 500 mW;(3)differential input voltage: +/-5V;(4)input voltage: +/-15 V;(5)short circuit duration: continuous;(6)operating temperature range: -55 to +125;(7)storage temperature range: -65 to +150;(8)lead temperature (soldering, 10 sec): 300.
