AD795JR: 运算放大器SOIC-8封装
The AD795 is a low noise, precision, FET input operational amplifier. It offers both the low voltage noise and low offset drift of a bipolar input op amp and the very low bias current of a FET-input device. The 1014(Ohm) common-mode impedance insures that the input bias current is essentially independent of common-mode voltage and supply voltage variations.
The AD795 has both excellent dc performance and a guaranteed and tested maximum input voltage noise. It features 1 pA maximum input bias current and 250 µV maximum offset voltage, along with low supply current of 1.5 mA max.
Furthermore, the AD795 features a guaranteed low input noise of 2.5 µV p-p (0.1 Hz to 10 Hz) and 11 NV(root)Hz Max noise level at 10 kHz. The AD795 has a fully specified and tested input offset voltage drift of only 3 µV/°C max.
The AD795 is useful for many high input impedance, low noise applications. The AD795J and AD795K are rated over the commercial temperature range of ) 0°C to +70°C.
The AD795 is available in 8-pin plastic mini-DIP and 8-pin surface mount (SOIC) packages.
