high performance FET input amplifiers.
G = +20 26
The AD8067 is designed to work in applications that require
24
high speed and low input bias current, such as fast photodiode
22
preamplifiers. As required by photodiode applications, the laser
G = +10 20
trimmed AD8067 has excellent dc voltage offset (1.0 mV max)
dB – 18
and drift (15 µV/°C max).
G = +8 GAIN 16
The FET input bias current (5 pA max) and low voltage noise
14
(6.6 nV/√Hz) also contribute to making it appropriate for precision applications. With a wide supply voltage range (5 V to 24 V)
12
and rail-to-rail output, the AD8067 is well suited for a variety of
10
applications that require wide dynamic range and low distortion.
