LM2902DTB

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902DTB is a quad operational amplifier manufactured by onsemi, housed in a TSSOP-14 package. It operates from single supplies of 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. Key electrical characteristics include a maximum input bias current of 250 nA, an output short-circuit protected design, and a common-mode input voltage range that includes the negative supply rail. The device supports an operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features true differential input stages with internal frequency compensation for stable operation across wide supply voltages.
• Includes short-circuit protected outputs and ESD clamps on inputs to enhance ruggedness without affecting normal device function.
• Supports single-supply operation where the common-mode input range extends to the negative power supply, eliminating the need for external biasing components.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix DTB corresponds to the TSSOP-14 package configuration required for your PCB layout. Confirm the operating temperature grade matches the application's thermal environment, as variants exist for commercial and extended industrial ranges. Ensure the ordering prefix aligns with any automotive qualification requirements such as AEC-Q100 if applicable to the final system.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-cost, quad amplifier is needed for single-supply applications requiring input signals near ground potential. The wide supply voltage range accommodates various battery-powered and industrial systems. Consider the TSSOP-14 package dimensions for space-constrained designs compared to standard SOIC or PDIP options.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM324 series family of single-supply quad operational amplifiers. The LM2902 variant specifically denotes an extended temperature range suitable for more demanding environments than the standard LM324. The DTB suffix identifies the thin-shrink small-outline package type used for surface-mount assembly.
