Key Features
- Wide supply voltage range: 3V to 32V single supply (or 1.5V to 16V dual supply)
- Ultra-low quiescent supply current: 500uA per amplifier
- Unity-gain bandwidth of 1MHz
- Output voltage swing to within 20mV of negative rail
- Industry-standard LM358/LM2904 pinout in compact VSSOP-8 footprint
- CMOS/TTL compatible output levels for single-supply operation
Applications
The LM2904DGKR is widely used in battery-powered portable equipment such as handheld instruments, smoke detectors, and IoT sensor nodes due to its low quiescent current and wide supply range. It excels in single-supply signal conditioning circuits, transducer amplifiers, and comparator applications where power consumption is critical. Its industry-standard pinout makes it a direct drop-in replacement for LM358 and LM2904 devices in existing designs.

Frequently Asked Questions
What is the supply voltage range for the LM2904DGKR?
The LM2904DGKR operates from a single supply of 3V to 32V, or a dual supply of 1.5V to 16V, making it suitable for both 3.3V/5V microcontroller systems and higher-voltage industrial designs.
Is the LM2904DGKR a drop-in replacement for the LM358?
Yes. The LM2904DGKR is functionally equivalent to the LM358 and shares the same pinout. The DGK suffix denotes the VSSOP-8 package, whereas many LM358 variants come in SOIC-8 or DIP-8; verify package compatibility before substituting.
What does the DGK suffix mean in LM2904DGKR?
DGK indicates the VSSOP-8 (8-pin Very Small Outline Plastic) package with a 0.65mm pin pitch. The R suffix denotes tape-and-reel packaging on a 3000-unit reel, suitable for automated SMT assembly.
What is the operating temperature range of the LM2904DGKR?
The LM2904DGKR commercial grade is rated for 0°C to +70°C. For extended industrial range of -40°C to +125°C, consider the LM2904BQDRQ1 or LM2904-Q1 automotive-grade variants from Texas Instruments.
