LM2902SNG

Instrumentation, Op Amps, Buffer Amps Overview

The LM2902SNG is a low-power, bipolar quad operational amplifier manufactured by onsemi. It features four independent high-gain amplifiers with internal frequency compensation, designed for automotive and industrial control systems. The device operates from a single power supply ranging from 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. Key electrical characteristics include a large signal open-loop voltage gain of 100 V/mV, an input bias current of up to 250 nA, and an output short-circuit current of 60 mA. It supports an operating temperature range of -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• True differential input stage allows common mode voltage range to extend to the negative supply rail.
• Outputs are short-circuit protected against ground faults.
• Single supply operation eliminates the need for external biasing components in many applications.
• Internally compensated for stability without external capacitors.

Instrumentation, Op Amps, Buffer Amps Applications

• Transducer amplifiers
• DC gain blocks
• Integrators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-14 package and the 'G' indicates Pb-Free compliance when ordering. Confirm the extended temperature grade (-40°C to +105°C) matches the application requirements, as opposed to the commercial grade LM324S. Ensure the source impedance remains low to maintain specified CMR and PSR performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring true differential inputs that include the negative supply rail. It is suitable for single-supply designs where external biasing is undesirable. Consider the -40°C to +105°C operating range for industrial environments. Compare against LM324S if commercial temperature range (0°C to +70°C) suffices for cost optimization.

Instrumentation, Op Amps, Buffer Amps Part Context

The LM2902S belongs to the LM324/LM2902 family of single-supply quad operational amplifiers. While electrically similar to the LM324S, the LM2902 variant is characterized for an extended industrial temperature range. Both share the same pinout and internal architecture but differ in guaranteed performance limits across temperature extremes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LM324SN is a compatible alternative with identical pinouts and functionality, limited to a 0°C to +70°C operating range.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LM2902S support dual supply operation?

Yes, the device can operate from split supplies ranging from ±1.5 V to ±16 V.

What is the maximum input voltage relative to the supply?

The input common mode voltage range extends to the negative supply. For supply voltages less than 32 V, the absolute maximum input voltage is equal to the supply voltage.
