ST's portfolio of rad-hard operational amplifiers for aerospace applications include low-noise, low-power, high-speed devices, all guaranteed up to 300 krad.
Rad-hard op-amps offer very good performances inside many applications such as communication satellites and space data acquisition. They are available with single- and dual-ranging supply voltage from 3 V up to 16 V, currents ranging from 200 µA up to 16 mA, a max frequency of up to 1 GHz and a minimum gain of 1. ST’s proprietary technologies used for this voltage range are BiCMOS and 0.25 µm CMOS.
The available packages are Flat8 and Flat8S.
