  • INA146: Offset voltage Vo - Total offset or offset of output amplifier

    TI Thinks Resolved
    Part Number: INA146 Hi, In the data sheet of INA146, two offset voltages are specified, each with RTI (Referred to Input). Is the Offset Voltage Vo the total offset or just the offset of the output amplifier? Best regards
