OP27FZ Product Details

General Description 
The OP27/OP37 precision operational amplifiers provide lower noise and higher speed with the same input offset and drift specifications as the OP07. Both parts have a 10uV offset,0.2uV/rC drift, and 1.8 million gain. Coupled with a low-voltage noise of 3.5nV//Hz at 10Hz and a low 1f noise corner frequency of 2.7Hz, the OP27/OP37 are op-
timized for accurate amplification of low-level signals. The OP27FZ features an 8MHz gain-bandwidth product and a 2.8V/us slew rate. For applications demanding higher speed, the OP37 has a 63MHz gain-bandwidth product, 17V/us slew rate, and is stable at gains of five or more.
An output swing of ±10V into 6002 together with low distortion make the OP27/OP37 ideal for professional audio applications.
For applications requiring greater precision or lower noise than the OP27FZ or OP37, see the MAX427/MAX437 and the MAX410/MAX412/MAX414data sheets.
