LM2902AS14-13

Overview

The LM2902AS14-13 is a quad operational amplifier manufactured by Diodes Incorporated, housed in an SO-14 package. It features four independent high-gain amplifiers with internally compensated unity gain bandwidth of 700kHz and large DC voltage gain of 100dB. The device operates from a single supply ranging from 3V to 36V or dual supplies of ±1.5V to ±18V. It offers low input bias current of 20nA and very low input offset voltage of 1mV typical for the A version. Supply current drain is 700µA and remains independent of the supply voltage magnitude.

Feature Summary

• Features wide power supply voltage range supporting both single and split supply configurations
• Includes internal frequency compensation ensuring stability at unity gain
• Input common-mode voltage range includes ground potential
• Differential input voltage range equals the total power supply voltage

Applications

• Transducer amplifiers
• DC gain blocks
• Active filters

Procurement Notes

Verify that the ordering suffix S14 corresponds to the SO-14 package type and -13 indicates tape and reel packaging. Confirm the 'A' designation ensures the specified low input offset voltage characteristics are met. Ensure the application environment stays within the -40°C to +125°C operating temperature range defined in the datasheet.

Selection Notes

Select this component when a quad amplifier configuration is required with low power consumption and high input impedance. The A-suffix variant is appropriate for applications demanding tighter input offset voltage specifications compared to standard versions. Verify that the output swing requirements align with the VCC-1.5V limitation under load conditions.
