The input bias current is 1 nA, which is fine for most resistive-sensor bridges but not for high-impedance sources like pH probes — there the 1 nA bias will cause a voltage drop across the source resistance. Input offset voltage is 285 µV, typical for a general-purpose bipolar input stage at this quiescent level. Each output can source or sink 25 mA, enough to drive a small relay or a modest analog front-end. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window is on record.","metaTitle":"LT1490AIS8#PBF Dual Rail-to-Rail Op-Amp, 200 kHz, 50 µA","metaDescription":"LT1490AIS8#PBF dual general-purpose op-amp from Analog Devices (LT® series).
