KR140UD20A
Dual-channel operational amplifier with high channel separation level (-85 dB). The circuit has an extra input for balancing capacitor. The balancing capacitor, connected between this input and inverting input increases the slew rate to 10 V/mks.
Ambient air temperature -60..+125 oC
Case types: 201.14-10, N01.16-2V
