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.
