LM2902AWYDT

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902AWYDT is a quad operational amplifier from STMicroelectronics, designed for automotive and industrial applications. It features four independent high-gain amplifiers with internal frequency compensation. Key electrical parameters include a gain-bandwidth product of 1.3 MHz, a slew rate of 400 mV/us, and an input offset voltage of 2 mV. The device operates on single supplies from 3 V to 30 V or dual supplies from ±1.5 V to ±15 V. It draws 1.5 mA total supply current and provides 40 mA output current per channel. It is housed in a SOIC-14 package and meets AEC-Q100 qualification standards.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix AWYDT against official STMicroelectronics documentation to confirm pinout, package dimensions, and temperature grade. Ensure the component matches the required AEC-Q100 automotive qualification level. Cross-reference datasheet specifications for input bias current and offset voltage tolerances before final integration into circuit designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when automotive-grade reliability is required alongside low power consumption. It serves as a direct replacement for standard LM2902 variants in space-constrained designs due to its SOIC-14 packaging. Consider the 1.3 MHz bandwidth and 400 mV/us slew rate for moderate-speed signal processing tasks requiring wide supply voltage flexibility.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LM2902W series of low-power bipolar operational amplifiers. It shares functional similarities with other members like the LM2902D and LM2902YPT but differs in package type and specific electrical parameter tolerances. The W suffix typically indicates a wider operating temperature range suitable for harsh environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes include LM2902D and LM2902YPT. Verify that alternative packages such as TSSOP-14 fit the PCB layout constraints. Confirm that the input offset voltage and bias current specifications of the substitute meet the original design requirements.
