QUAD OPERATIONAL AMPLIFIERS
LM248/LM348 true quad LM741. consists four independent, high-gain, internally compensated, low-power operational amplifiers which have been designed provide functional characteristics identical those familiar LM741 operational amplifier. addition total supply current four amplifiers comparable Supply current single LM741 type Amp.
Other features include input offset currents input bias current which much less than those standard LM741. Also, excellent isolation between amplifiers been achieved independently biasing each amplifier using layout techniques which minimize thermal coupling.
