Overview
The LM248N is a quad operational amplifier manufactured by Texas Instruments, housed in a 14-pin PDIP 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 from a single supply between 8 V and 36 V, or dual supplies of ±4 V to ±18 V, it draws 2.4 mA of quiescent current. Each channel provides 25 mA of output current, and the device offers a common-mode rejection ratio of 90 dB with an input voltage noise density of 60 nV/sqrt Hz.
Feature Summary
- Integrates four independent high-gain operational amplifiers within a single compact package.
- Supports operation from wide single-supply voltages up to 36 V or split dual supplies.
- Delivers 25 mA output drive capability per channel for direct load interfacing.
Applications
- General-purpose analog signal conditioning circuits
- Multi-channel sensor interface designs
- Industrial control system signal processing
Procurement Notes
Verify the specific manufacturer marking and date code against official Texas Instruments documentation to confirm authenticity. Ensure the PDIP-14 package dimensions match your PCB footprint requirements. Confirm that the operating temperature range of -25 C to +85 C aligns with your environmental specifications before finalizing procurement.
Selection Notes
Select this component when a quad configuration is required for cost-sensitive applications. It is suitable for designs needing moderate bandwidth and high output current. Consider alternative packages if surface-mount technology is preferred over through-hole mounting.
Part Context
This part belongs to the LM248 series of operational amplifiers. It serves as a multi-channel solution for general-purpose amplification tasks. The device is designed for robust performance in industrial and commercial environments requiring multiple amplifier channels.
Replacement Considerations
The LM348 is a pin-compatible functional equivalent. Verify electrical parameter differences such as input offset voltage and bandwidth before substitution.
