Add To BomAD8642ARZ General Description
The AD8641/AD8642/AD8643 are low power, precision JFET input amplifiers featuring extremely low input bias current and rail-to-rail output. The ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables designers to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems. The outputs remain stable with capacitive loads of more than 500 pF.
Features
- Low Supply Current: 250 µA max
- Very Low Input Bias Current: 1 pA max
- Low Offset Voltage: 750 µV max
- Single-supply Operation: 5 V to 26 V
- Dual-supply Operation: ±2.5 V to ±13 V
- Rail-to-rail Output
- Unity Gain Stable
- No Phase Reversal
Application
- Line-/battery-powered instruments
- Photodiode amplifiers
- Precision current sensing
- Medical instrumentation
- Industrial controls
- Precision filters
- Portable audio
- ATE
