What are the key features of OPA4379AIPWRG4?
- 1.8 V minimum supply with 2.9 µA quiescent current per channel enabling ultra-low-power battery-operated sensor designs
- Rail-to-rail input and output with 100 dB typical CMRR supporting precision differential signal acquisition in tight voltage budgets
- Quad op amp in a 14-pin SOIC package with 90 kHz gain-bandwidth product for space-efficient multi-channel filtering
What is OPA4379AIPWRG4 used for?
The OPA4379AIPWRG4 is optimized for battery-powered portable instruments, wearable health monitors, and IoT sensor nodes that require four independent amplifier channels from a single low-voltage rail. Its 2.9 µA per-channel quiescent current extends battery life in always-on signal conditioning front ends. The rail-to-rail I/O and 100 dB CMRR make it suitable for bridge sensor amplification, ECG signal chains, and low-frequency active filter implementations.
