description
The OP27 operational amplifiers combine out-
standing noise performance with excellent
precision and high-speed specifications. The
wideband noise is only 3 nV/√Hz and with the 1/f
noise corner at 2.7 Hz, low noise is maintained for
all low-frequency applications.
The outstanding characteristics of the OP27 make
these devices excellent choices for low-noise
amplifier applications requiring precision
performance and reliability.
The OP27 series is compensated for unity gain.
The OP27A and OP27C are characterized for
operation over the full military temperature range
of −55°C to 125°C.
