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 V and maximum drift of 0.6 V/C make the OP27 ideal for precision instrumentation applications. Exceptionally 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/s slew rate provide excellent dynamic accuracy in high speed, dataacquisition systems.
