LM148 four-channel operational amplifier, provides functional characteristics identical to those of the familiar UA741 operational amplifier.
The LM148 family consists of four independent, high‑gain, internally compensated, low‑power operational amplifiers that match the classic UA741 characteristics while consuming only the current of a single UA741. They are pin‑compatible with the LM124 and are offered in both DIP and SO (micro‑package) formats.
Key specifications include a supply voltage rating of up to +22 V, typical input offset voltage of 25 mV, typical input bias current of 30 nA, and a gain‑bandwidth product of 1.3 MHz. The devices feature 120 dB isolation between amplifiers, overload protection, and are available in a 14‑pin plastic package.
