Circuit Considerations for LMV324DR2G

Typical Application Configurations

The LMV324DR2G is a versatile quad operational amplifier suitable for a wide range of applications:

Battery-Powered Instruments: Low 410 µA supply current per amplifier makes it ideal for portable and battery-powered equipment[reference:17]
Sensor Signal Conditioning: Rail-to-rail output and 1 nA input bias current for high-impedance sensor interfaces[reference:18]
Active Filters: 1 MHz gain-bandwidth product supports active filter designs for signal processing[reference:19]
Portable Test Equipment: Wide temperature range (–40°C to 85°C) and low power consumption[reference:20]
Audio Signal Processing: 160 mA output current per channel drives audio signal lines[reference:21]
Data Acquisition Systems: General-purpose op-amp for signal conditioning in data acquisition systems[reference:22]

PCB and Power-Supply Guidance

Op-amp performance depends on layout, bypassing, and power supply quality:

Bypass Capacitors: Place 0.1 µF ceramic capacitors close to each supply pin to reduce noise and oscillation
Layout Considerations: Keep input traces short and away from noisy digital signals. Use a ground plane for optimal performance
Feedback Network: Keep feedback components close to the inverting input to minimize parasitic capacitance
Unused Amplifiers: Tie unused inputs to ground or a reference voltage to prevent oscillation
Single Supply Operation: Rail-to-rail output enables single-supply operation down to 2.7V
Verify the recommended PCB footprint from the official datasheet before production
