AD848/AD849 are high performance, low power monolithic operational amplifiers. AD848 is internally compensated for stable operation with closed-loop gains of 5 or greater. AD849 is fully decompensated for higher open-loop gains up to 63 dB.
The document describes the AD848 and AD849 as high-speed, low-power monolithic operational amplifiers utilizing Analog Devices' junction-isolated complementary bipolar (CB) process. The AD848 is internally compensated for closed-loop gains of 5 or greater, while the AD849 is fully decompensated for gains greater than 24.
| Gain Bandwidth (AD849) | 725 MHz |
|---|---|
| Gain Bandwidth (AD848) | 175 MHz |
| Supply Current | 4.8 mA |
| Slew Rate | 300 V/µs (AD849) |
| Settling Time to 0.1% | 80 ns |
| Input Voltage Noise (AD849) | 3 nV/√Hz |
The AD848 is internally compensated so that it is stable for closed loop gains of 5 or greater.
The AD849 is fully decompensated and is stable at gains greater than 24.
They are suitable for cable drivers, data acquisition systems, video and RF amplification, and signal generators.
