BETATL074Quad FET-input operational amplifier
Four low-input-current channels for analog signal paths.
TL074 contains four FET-input operational amplifiers in a fourteen-pin package. Separate input pairs and outputs allow four feedback circuits to share one pair of supply rails. Its low input current suits analog buffers, active filters and signal-conditioning stages. The selected commercial parts are TL074CN in PDIP-14 and TL074CDR in SOIC-14, rated for 0 to 70°C. TI identifies both legacy SFAB and newer RFB silicon under non-H part numbers. This page labels its electrical data as the original-die tables in revision W; verify the shipment’s CSO identifier before using revision-specific limits. The example uses ±15 V rails, a 0 V signal midpoint and 0.40 V input. Channel A has a gain of four and ideally produces 1.60 V; the other three channels are defined, lightly loaded followers. Input/output headroom, offset, bias current and signal speed limit real accuracy.
