GENERAL DESCRIPTION OP27GSZ-REEL7
The OP27GSZ OP27 precision operational amplifier combines the low
offset and drift of the OP07 with both high speed and low noise.
Offsets down to 25 μV and maximum drift of 0.6 μV/°C make
the OP27 ideal for precision instrumentation applications. Low
noise, en = 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/μs slew rate provide 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 IB and IOS to ±20 nA and 15 nA,
respectively.
The output stage has good load driving capability. A guaranteed
swing of ±10 V into 600 Ω and low output distortion make the
OP27 an excellent choice for professional audio applications.
