LM158J

Overview

The LM158J is a dual general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-pin ceramic dual in-line package (CDIP). It features two independent high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 3 V to 32 V or split supplies. Key electrical parameters include a gain-bandwidth product of 700 kHz, a slew rate of 300 mV/µs, and a maximum input offset voltage of 5 mV. The common-mode rejection ratio is specified at 70 dB minimum. It supports an operating temperature range from -55 °C to 125 °C.

Feature Summary

• Dual operational amplifiers with internal frequency compensation designed for wide voltage range operation
• Input common-mode voltage range includes ground, allowing direct sensing near zero volts
• Low power supply drain that remains essentially independent of the supply voltage magnitude
• Capable of output voltage swing to ground even when operated from a single power supply

Applications

• Transducer amplifiers
• DC gain blocks
• Single-supply logic system interfacing
• General-purpose signal conditioning

Procurement Notes

Verify the specific suffix 'J' corresponds to the ceramic DIP package variant rather than plastic or surface-mount versions. Confirm the datasheet revision matches the required military or industrial specifications. Ensure the ordering information aligns with the manufacturer's current active status for this package type. Cross-reference pinout configurations to guarantee compatibility with existing board layouts.

Selection Notes

Select this component when a ruggedized ceramic package is required for harsh environments. The 700 kHz bandwidth suits low-frequency applications where precision is secondary to reliability. Consider the 5 mV input offset voltage for DC accuracy requirements. Verify that the 300 mV/µs slew rate meets the dynamic signal requirements of the target circuit design.

Part Context

The LM158 series consists of dual operational amplifiers designed for single-supply operation. The 'J' suffix typically denotes the ceramic dual in-line package variant offered by Texas Instruments. This family provides a cost-effective solution for general-purpose analog signal processing tasks requiring moderate speed and wide supply voltage tolerance.
