LM248DR

Overview

The LM248DR is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin SOIC package. It features a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/us. The input offset voltage is 6 mV, with an input bias current of 200 nA. Operating on a single supply from 8 V to 36 V or dual supplies from 4 V to 18 V, it draws 2.4 mA of quiescent current per channel. Each output can source 25 mA, providing a common-mode rejection ratio of 90 dB and an input voltage noise density of 60 nV/sqrt Hz.

Feature Summary

• Integrates four independent high-gain operational amplifiers within a compact surface-mount package for space-constrained designs.
• Delivers robust performance with a 1 MHz gain-bandwidth product and 500 mV/us slew rate for general-purpose signal processing.
• Supports wide single-supply operation up to 36 V or split-rail configurations for flexible power management.

Applications

• General-purpose analog signal conditioning circuits
• Active filter implementations requiring moderate bandwidth
• Sensor interface amplification stages

Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the 14-SOIC footprint matches the target PCB layout dimensions. Ensure the operating temperature range of -25 C to +85 C aligns with the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a quad op-amp solution is required with a 1 MHz bandwidth and 25 mA output drive capability. It is suitable for applications needing wide single-supply voltage tolerance up to 36 V. Consider alternatives if lower input bias current or higher precision offset voltage is critical, as this device prioritizes general-purpose utility over ultra-low noise specifications.

Part Context

This device belongs to the LM248 series of quad operational amplifiers produced by Texas Instruments. It shares functional similarities with other industry-standard quad op-amps but offers specific electrical characteristics tailored for general-purpose analog applications. The DR suffix indicates a reel-packaged variant designed for automated surface-mount assembly processes.

Replacement Considerations

LM124DR: Offers similar quad configuration with slightly different electrical parameters including 1.2 MHz GBP and 30 mA output current.

FAQ

What is the maximum supply voltage for the LM248DR?

The maximum supply voltage is 36 V for single-supply operation or +/- 18 V for dual-supply operation.

Does the LM248DR include a shutdown feature?

No, the LM248DR does not have a shutdown pin; it operates continuously when powered.
