Introduction
The QN321 strikes a balance between performance and economy for low-power systems. It features a high unity-gain bandwidth and a guaranteed slew rate of 0.4V/μs, while drawing only 500μA quiescent current per amplifier (at 5V). The input common-mode range includes ground, enabling operation in both single-supply and dual-supply applications. It also drives large capacitive loads with ease. The QN321 comes in a SOT-23-5L package. Overall, the QN321 is a low-power, wide supply range, high-performance op-amp that can be designed into a wide variety of applications at an affordable price without consuming valuable board space.
Features
- Gain-Bandwidth Product: 1MHz
- Low Supply Current: 500μA
- Low Input Bias Current: 45nA
- Wide Supply Voltage Range: +3V to +32V
Applications
- Charger
- Power Supply
- Industrial
- Desktop
- Communication Infrastructure
