GENERAL DESCRIPTION

4V– (CASE)

NC = NO CONNECT

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 µV and drift of 0.6 µV/°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/µsec 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_Band I_OSto 20 nA and 15 nA,

respectively.
