(TJ Wnt LH2I08A TECHNOLOGY “Operational Amplifiers FEATURES DESCRIPTION = Guaranteed 2nA Max. Input Bias Current The LH2108A series of precision operational amplifiers is = Guaranteed 600pA Max. Supply Current particularly well suited for high source impedance appli- = Guaranteed 0.5mV Max. Offset Voltage cations requiring low offset and bias currents, as well as = Guaranteed 5pV/°C Max. Drift low power dissipation. Unlike FET input amplifiers, the ® Wide Supply Voltage Range: + 2V to +20V offset and bias currents of the LH2108A do not change = Interchangeable with Other Manufacturers’ LH2108 significantly with temperature variations. Advanced de- sign, processing and testing techniques make Linear’s LH2108A a superior choice over previous devices.
