OP Amps, Buffer Amps ICs

LM2904DGKR Description

The LM2904DGKR from Texas Instruments is a dual-channel general-purpose operational amplifier (op-amp) housed in an 8-VSSOP package, designed for surface-mount applications. Operating over a wide supply voltage range (3V to 26V), it delivers robust performance with a low supply current of 500µA per channel, making it ideal for power-sensitive designs. This RoHS3-compliant and REACH-unaffected IC features a gain bandwidth product of 700 kHz and a slew rate of 0.3V/µs, ensuring stable amplification for low-to-moderate frequency signals. With low input bias current (20 nA) and input offset voltage (3 mV), it minimizes errors in precision circuits.

LM2904DGKR Features

• Dual-channel design: Two independent op-amps in a compact 8-VSSOP package.
• Wide supply range: 3V to 26V operation, suitable for battery-powered and industrial applications.
• Low power consumption: 500µA per channel ensures energy efficiency.
• High output drive: 30 mA output current per channel for driving moderate loads.
• Low noise and offset: 20 nA input bias current and 3 mV offset voltage enhance accuracy.
• Robust packaging: Tape & Reel (TR) for automated assembly, MSL 1 (Unlimited) for extended shelf life.

LM2904DGKR Applications

The LM2904DGKR excels in portable electronics, sensor interfaces, and industrial control systems due to its low power and wide voltage range. Key applications include:

• Signal conditioning for sensors (e.g., thermocouples, pressure sensors).
• Active filters and precision integrators in audio and instrumentation circuits.
• Battery-powered devices (e.g., IoT nodes, wearables) where efficiency is critical.
• Motor control and power management systems requiring stable amplification.

Conclusion of LM2904DGKR

The LM2904DGKR is a versatile, cost-effective op-amp offering low power, wide voltage operation, and reliable performance in space-constrained designs. Its dual-channel configuration, low noise, and robust packaging make it a preferred choice for industrial, automotive, and consumer electronics. Engineers favor this IC for its balance of performance and efficiency, particularly in applications demanding precision and durability.
