LH740AlLH740AC FET Input Operational Amplifier
General Description
The LH740A/LH740AC is a FET input, general purpose operational amplifier with high input impedance, closely matched input characteristics; and good slew rates.
Input offset
voltage is tYpi· cally 10.
0 mV at 25°C, while input bias current is
less than 100 pA at 25° G.
Offset current is typi·
cally less than 40 pA at 25°C.
Other important design features include:
• Internal 6 d B/octave frequency compensation • Unity gain slew rate in excess of 6 VliJs • Unity gain bandwidth of 1 MHz • Input offset is adjustable with a single 10k pot • Pin compatible with LM741, LM709, LM 101 A.
