description

The OP27 operational amplifiers combine outstanding

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.
