LM2902N

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902N 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 device operates on a single supply voltage ranging from 3 V to 32 V, with a typical operating supply current of 1.5 mA. Key electrical parameters include an input offset voltage of 7 mV, input bias current of 250 nA, and an output current capability of 40 mA per channel.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Four independent high-gain operational amplifiers with internal frequency compensation
• Wide power supply range supporting both single and split supply configurations
• Input common-mode voltage range includes the negative rail for ground detection
• Low power supply current drain that remains independent of supply voltage magnitude

Instrumentation, Op Amps, Buffer Amps Applications

• Consumer electronics
• Sensor and instrumentation circuits
• Motor drive and control systems
• Test and measurement equipment

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix N indicates the PDIP-14 through-hole package configuration. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the ordering part number matches the required pinout and thermal characteristics for your PCB layout design before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when four independent amplifiers are required within a single package. It is suitable for applications needing wide supply voltage flexibility and ground-referenced input signals. Consider the 1 MHz bandwidth and 500 mV/us slew rate for general-purpose signal conditioning tasks where low power consumption is a priority.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM2902 series serves as a quad-channel counterpart to the dual-channel LM324. Both belong to the industry-standard bipolar op-amp family designed for automotive and industrial control systems. The LM2902 provides four channels, offering higher integration density compared to the two-channel LM324 while maintaining similar low-power operational characteristics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LM324N: Dual-channel alternative requiring two packages for equivalent functionality. LM2902KNSRG4: Surface-mount SOIC-14 variant with identical electrical performance. LM2902BAIPWR: TSSOP-14 surface-mount option with improved offset voltage specifications.
