GENERAL DESCRIPTION
The OP27 precision operational amplifier combines the low
offset and drift of the OP07 with both high speed and low noise.
Offsets down to 25
μ
V and drift of 0.6
μ
V/
°
C maximum make
the OP27 ideal for precision instrumentation applications.
Exceptionally low noise, e
n
= 3.5 nV/
√
Hz
, at 10 Hz, a low 1/f
noise corner frequency of 2.7 Hz, and high gain (1.8 million),
allow accurate high-gain amplification of low-level signals. A
gain-bandwidth product of 8 MHz and a 2.8 V/
μ
sec slew rate
provides excellent dynamic accuracy in high-speed, data-
acquisition systems.
A low input bias current of
±
10 nA is achieved by use of a
bias-current-cancellation circuit. Over the military temperature
range, this circuit typically holds I
B
and I
OS
to
±
20 nA and 15 nA,
respectively.
The output stage has good load driving capability. A guaranteed
swing of
±
10 V into 600
and low output distortion make the
OP27 an excellent choice for professional audio applications.
