Overview
The LMV932DR2G, produced by onsemi, is a dual low-voltage operational amplifier that operates on single-sided power supplies ranging from 1.8 V to 5.0 V. This CMOS-based amplifier features rail-to-rail input and output swing, making it ideal for applications requiring high signal-to-noise performance. The device is available in a Micro8 or SOIC-8 package, which is beneficial for crowded PCBs due to its small size. The LMV932 is designed for low quiescent current, eliminating output crossover distortion and phase-reversal from overdriven inputs, making it suitable for battery-operated and portable devices.
