LM2904DR

LM2904DR Description

The LM2904DR from Texas Instruments is a general-purpose dual operational amplifier housed in an 8-SOIC package, designed for surface-mount applications. This RoHS3-compliant, REACH-unaffected IC operates over a wide supply voltage range (3V to 26V), making it versatile for both low and high-voltage systems. With a low input bias current (20nA) and moderate slew rate (0.3V/µs), it balances precision and speed for cost-sensitive designs. The 700 kHz gain bandwidth product and 40mA output current per channel ensure reliable performance in signal conditioning and amplification tasks. Packaged in Tape & Reel (TR), it is ideal for automated assembly processes.

LM2904DR Features

• Dual-channel design: Integrates two independent op-amps in a single package, saving board space.
• Low power consumption: 500µA per channel supply current, suitable for battery-operated devices.
• Wide supply range: 3V to 26V operation supports diverse applications.
• Low input offset voltage (3mV): Enhances accuracy in DC-coupled circuits.
• High output drive (40mA): Capable of driving moderate loads directly.
