What are the key features of LM2904DGKR-ND?
- Dual op-amp in an 8-pin VSSOP package offering 2 independent amplifier channels in a space-saving SMD footprint for high-density PCB designs
- Single-supply operation from as low as 3 V enabling use in battery-powered and low-voltage embedded applications without split-rail power supplies
- General-purpose frequency response suitable for audio preamplification, active filtering, and DC signal conditioning in cost-sensitive consumer and industrial designs
What is LM2904DGKR-ND used for?
The LM2904DGKR-ND is used in signal conditioning front-ends for sensors, where its 2 independent channels handle differential amplification and offset correction in a single compact package. It suits active low-pass or high-pass filter designs in audio processing, motor current sensing, and instrumentation amplifier stages that operate from a single 3.3 V to 5 V supply rail. The VSSOP package minimises PCB area, making it attractive for space-constrained IoT nodes and portable measurement devices.

Frequently Asked Questions
How many op-amp channels does LM2904DGKR-ND integrate, and what is its minimum supply voltage?
The LM2904DGKR-ND integrates 2 independent general-purpose op-amp channels in a single 8-pin VSSOP package. It operates from a minimum single supply of approximately 3 V (or ±1.5 V dual supply), making it compatible with 3.3 V microcontroller-based systems and battery-powered sensor nodes without requiring a negative rail.
For which sensor signal-conditioning circuits is LM2904DGKR-ND a cost-effective choice?
Resistive-bridge sensors, thermistor linearisation networks, and photodiode transimpedance amplifiers are common applications for the LM2904DGKR-ND. Its 2 channels allow one device to handle both the amplification stage and a reference buffer simultaneously, reducing BOM cost and board area in low-frequency sensor interfaces below 100 kHz bandwidth.
What package does LM2904DGKR-ND use, and how does its size compare to a standard SOIC-8?
The LM2904DGKR-ND comes in an 8-pin VSSOP package with a 0.65 mm pitch and a body measuring approximately 3.0 mm × 3.0 mm, which is roughly 60% smaller in footprint than a standard SOIC-8 at 4.9 mm × 3.9 mm. This compact SMD form factor suits high-density PCB layouts in portable instruments where board area is constrained.
When is LM2904DGKR-ND a lower-cost alternative to precision op-amps in non-critical signal paths?
In applications where input offset voltage of a few millivolts is acceptable—such as audio preamps, comparator-light circuits, or non-precision voltage followers—the LM2904DGKR-ND provides adequate performance at lower cost than precision op-amps with sub-100 µV offset. Its general-purpose bandwidth suffices for signals below 1 MHz, avoiding the cost premium of wideband or auto-zero alternatives.
