LM148QML Quad
LM148QML Quad Amps
LM148 true quad LM741. consists four independent, high gain, internally compensated, 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. LM148 used anywhere multiple LM741 LM1558 type amplifiers being used applications where amplifier matching high packing density required.

Application Hints
LM148 series quad power LM741 amps. proliferation quad amps, these first offer convenience familiar, easy operating characteristics LM741 amp. those applications where LM741 amps have been employed, LM148 series amps employed directly with change circuit performance. package pin-outs such that inverting input each amplifier adjacent output. addition, amplifier outputs located corners package which simplifies board layout minimizes package related capacitive coupling between amplifiers. input characteristics these amplifiers allow differential input voltages which exceed supply voltages. addition, either input voltages within operating common-mode range, phase output remains correct. negative limit operating common-mode range exceeded both inputs, output voltage will positive. input voltages which greatly exceed maximum supply voltages, either differentially common-mode, resistors should placed series with inputs limit current. Like LM741, these amplifiers easily drive capacitive load throughout entire dynamic output voltage current range. However, very large capacitive loads must driven non-inverting unity gain amplifier, resistor should placed between output (and feedback
connection) capacitance reduce phase shift resulting from capacitive loading. output current each amplifier package limited. Short circuits from output either ground power supplies will destroy unit. However, multiple output shorts occur simultaneously, time duration should short prevent unit from being destroyed result excessive power dissipation chip. with most amplifiers, care should taken lead dress, component placement supply decoupling order ensure stability. example, resistors from output input should placed with body close input minimize "pickup" maximize frequency feedback pole which capacitance from input ground creates. feedback pole created when feedback around amplifier resistive. parallel resistance capacitance from input device (usually inverting input) ground frequency pole. many instances frequency this pole much greater than expected frequency closed loop gain consequently there negligible effect stability margin. However, feedback pole less than approximately times expected frequency lead capacitor should placed from output input amp. value added capacitor should such that time constant this capacitor resistance parallels greater than equal original feedback pole time constant.
