For Typical Characteristic Performance Curves, refer to MC34001, 34002, 34004 data sheet.
NOTE: 3. Input bias currents of JFET input op amps approximately double for every 10°C rise in junction temperature. To maintain junction temperatures as
close to ambient as is possible, pulse techniques are utilized during test.
