LM2902N

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902N is a quad operational amplifier manufactured by TAEJIN, housed in a DIP-14 package. It features four independent high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 2.0 V to 30 V or split supplies up to ±15 V. Key electrical characteristics include a typical input offset voltage of 3 mV at 25°C and a maximum of 7 mV. The supply current drain is low and independent of the supply voltage magnitude, typically 1.1 mA. The common-mode input voltage range includes ground (GND), allowing direct sensing near zero volts.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation on the component marking against the specified TAEJIN branding. Confirm the package type is DIP-14 and matches the ordering information for the LM2902N variant. Ensure the datasheet revision aligns with the required specifications for your design. Cross-reference the absolute maximum ratings to ensure compliance with your system's voltage limits.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier configuration is required for single-supply applications. The inclusion of ground-referenced common-mode input capability makes it suitable for sensor interfacing where signals approach zero volts. Consider the thermal performance within the -40°C to +105°C operating range for industrial environments.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM2902 series of quad operational amplifiers. It is designed as a cost-effective solution for general-purpose analog signal processing. The DIP-14 package facilitates through-hole mounting on printed circuit boards, supporting legacy designs and prototyping workflows requiring robust mechanical connections.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check pinout compatibility with other quad op-amps in the DIP-14 package. Verify if alternative manufacturers offer equivalent electrical parameters such as input offset voltage and supply current. Ensure the replacement supports the same wide single-supply voltage range and ground-referenced input requirements.
