Unity Gain Stable
The A275 is a high performance hybrid differential op-amp developed as a pulse amplifier for spaceborne nuclear
instrumentation.
Its low power dissipation (15 mW), high slew rate (100 V/碌s), and low input noise (4 nV/鈭欻z), make it ideal for use in a
wide range of op-amp applications. The A275 is packaged in a standard 14-pin hybrid DIP.
