Analog Devices ADA4177 series are precision op amps that combine both input overvoltage protection (OVP) and input electromagnetic interference (EMI) filtering whilst maintaining low maximum bias current and rail-to-rail output operation. Typical applications include Wireless base station control circuits, Optical network amplification, Instrumentation, Sensor conditioning and
Precision filters.
Low offset voltage: 60μV maximum at 25°C (8-lead and 14-lead SOIC)
Low offset voltage drift: 1μV/°C maximum (8-lead and 14-lead SOIC)
Low input bias current: 1nA maximum at 25°C
Low voltage noise density: 8nV/√Hz typical at 1kHz

Unity-gain crossover (AV = +1): 3.5MHz typical
−3dB bandwidth (AV = +1): 6MHz typical
Dual-supply operation:
Specified at ±5V to ±15V, operates over ±25 V to ±18V
Unity-gain stable
No phase reversal when inputs exceed common-mode range
