LM2902N Description

The LM2902N from Texas Instruments is a general-purpose quad operational amplifier housed in a 14-pin DIP package. Designed for through-hole mounting, it operates over a wide supply voltage range of 3V to 32V, making it versatile for both low and high-voltage applications. Part of the LinCMOS™ series, it features low input bias current (45 nA) and moderate gain bandwidth (1 MHz), ensuring stable performance in precision analog circuits. With four independent op-amps in a single package, it offers space and cost efficiency for multi-channel designs.

LM2902N Features

• Wide Supply Range: 3V to 32V, suitable for battery-powered and industrial systems.
• Low Power Consumption: Only 1.5mA supply current per amplifier, ideal for energy-sensitive applications.
• High Output Drive: 40mA output current per channel, capable of driving moderate loads.
• Low Input Offset Voltage (2 mV): Enhances accuracy in signal conditioning and sensor interfacing.
• Robust Construction: ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance.
• Extended Temperature Range: Reliable operation in harsh environments.
