LH740A/LH740AC Input Operational Amplifier
LH740A/LH740AC input, general purpose operational amplifier with high input impedance, closely matched input characteristics, good stew rates. Input offset voltage typically 10.0 while input bias current less than Offset current typi cally less than Other important design features include:
Internal dB/octave frequency compensation
Unity gain slew rate excess V/j,is
Unity gain bandwidth
Input offset adjustable with single
compatible with LM741, LM709, LM101A.
Excellent offset current match over tempera ture, typically
Output continuously short-circuit proof
Excellent open loop gain, typically excess
Guaranteed over full military temperature range
LH740A/LH740AC intended fulfill wide variety applications requiring extremely bias currents such integrators, sample hold amplifiers, general purpose operational amplifier applications.
LH740A specified operation over -55'C military temperature range. LH740AC specified operation over temperature range.
