DescriptionThe AD8067 FastFETampisa voltagefeedbackamplifierwith FET inputs offeringwide bandwidth (54 MHz @ G = +10) and high slewrate (640 V/µs).The AD8067is fabricatedin a proprietary,dielectrically isolatedeXtra FastComplementary Bipolarprocess (XFCB) thatenables highspeed,low power,and highperformance FET input amplifiers.
The AD8067 is designedto work in applicationsthatrequire high speedand low input bias current,suchas fastphotodiode preamplifiers.Asrequiredbyphotodiode applications,the laser trimmed AD8067 has excellent dcvoltage offset (1.0 mV max) and drift (15µV/°C max).
The FET input bias current (5 pAmax) and low voltage noise (6.6 nV/Hz) alsocontribute to makingitappropriate for precision applications.Witha wide supply voltage range (5 V to 24 V) and rail-to-railoutput,the AD8067 is well suitedto a variety of applicationsthatrequire wide dynamic range and low distortion.
The AD8067 amplifier consumes only6.5 mA ofsupplycurrent,while capable of delivering 30 mA ofload current and driving capacitiveloads of100 pF.The AD8067 amplifier is available in a SOT-23-5 package and is rated tooperate over theindustrial temperature range,40°C to +85°C.
