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. NC = NO CONNECT Figure 2. 8-Lead CERDIP – Glass Hermetic Seal (Z-Suffix),
