LM148J/PB

Overview

The LM148J/PB is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin Ceramic Dual In-line Package (CDIP). It provides four independent, high-gain, internally compensated amplifiers designed to replicate the functional characteristics of the standard 741 op amp. The device features low supply current drain of 0.6 mA per amplifier and includes built-in overload protection for both inputs and outputs. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Pin-compatible with the LM124 series
• Class AB output stage eliminates crossover distortion
• High degree of isolation between amplifiers minimizes thermal coupling

Applications

• Direct replacement for multiple 741 or 1558 type amplifiers
• Applications requiring high packing density
• Circuits demanding precise amplifier matching

Procurement Notes

Verify that the CDIP-14 package matches your board layout requirements. Confirm RoHS compliance status as indicated in the packaging addendum. Ensure handling procedures account for limited ESD protection during storage and installation.

Selection Notes

Select this component when legacy 741 performance is required but lower power consumption is necessary. It serves as a direct drop-in replacement for single 741 units while providing four channels. Consider the ceramic package for environments requiring hermetic sealing.

Part Context

This part belongs to the LM148-N family, which also includes LM248-N and LM348-N variants. These devices are categorized as true quad 741 operational amplifiers. The LM148 specifically targets military and industrial applications due to its extended temperature rating and robust construction.
