工作原理
CMOS input stage provides virtually zero input bias current (1 pA), ideal for high-impedance sensors. Rail-to-rail input and output stages maximize dynamic range at low supply voltages. Internal compensation ensures stability at unity gain. The wide supply range allows use from single-cell Li+ (1.8V) to ±7.5V dual supply.
应用
- High-impedance sensor interface
- Low-voltage signal conditioning
- Portable medical instrument
- Photodiode transimpedance
