Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging and lead-free compliance. Confirm the ISW designation corresponds to the industrial temperature grade (-40°C to +85°C) and the SW package type. Ensure the source document explicitly supports these specific ordering codes before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when requiring a combination of high speed and low DC offset in a quad configuration. It serves as a direct replacement for older JFET duals like the LF412A or OP-215 by utilizing four channels in a single package. Consider its phase reversal immunity for servo systems where inputs may exceed common-mode limits.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1057/LT1058 family of matched JFET input op amps. The LT1058 provides four amplifiers in a standard 14-pin equivalent footprint (SW package), offering significant accuracy improvements over existing JFET quad amplifiers while saving board space and power dissipation compared to discrete solutions.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet confirms the LT1057/LT1058 can replace LF353, LF412, TL072, and OP-215 duals, as well as LF347, LF444, TL074, and TL084 quads.
