AD8067

高增益带宽产品，精密快速FET⑩运算放大器 High Gain Bandwidth Product, Precision Fast FET⑩ Op Amp

Product Details

The  _FastFET_™ amp is a voltage feedback amplifier with FET inputs offering wide bandwidth 54 MHz @ G = +10 and high slew rate 640 V/µs.  The AD8067 is fabricated in a proprietary, dielectrically isolated eXtra Fast Complementary Bipolar process XFCB that enables high speed, low power and high performance FET input amplifiers.

The AD8067 is designed to work in applications that require high speed and low input bias current, such as fast photodiode preamplifiers. As required by photodiode applications, the laser trimmed AD8067 has excellent dc voltage offset 1.0 mV max and drift 15 µV/°C max.

The FET input bias current 5 pA max and low voltage noise 6.6 nV/√Hz also contribute to making it appropriate for precision applications. With a wide supply voltage range 5 V to 24 V and rail-to-rail output, the AD8067 is well suited for a variety of applications that require wide dynamic range and low distortion.

The AD8067 amplifier is available in a SOT-23-5 package and is rated to operate over the industrial temperature range of -40°C to +85°C.
