LTC2058IMSE#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2058IMSE#TRPBF is a dual, low noise, zero-drift operational amplifier housed in a 12-lead plastic MSOP package. It operates within a supply voltage range of 4.75V to 36V and supports an industrial temperature range from -40°C to 85°C. Key electrical specifications include a maximum input offset voltage of 5μV and a typical gain-bandwidth product of 2.5MHz. The device features rail-to-rail output swing, unity gain stability, and a shutdown mode for power reduction.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the IMSE designation corresponds to the industrial temperature grade (-40°C to 85°C) and the 12-lead MSOP package. Ensure compatibility with PCB footprints requiring connection of the exposed pad to the negative supply rail.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision without external trimming. The dual configuration offers cost efficiency compared to single-channel counterparts. Consider the 2.5MHz bandwidth for moderate speed requirements. Evaluate source impedance effects on input bias current noise if interfacing with high-impedance sensors.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the LTC2058 handle input bias current noise?

The input bias current consists of diode leakage and charge injection. Adding external capacitance at the inputs can reduce the effective DC error and lower the input current noise density.

What is the purpose of the GUARD pin in the MSE package?

The GUARD pin provides a guard ring connection with no internal circuit connection, intended to minimize leakage currents and improve performance in high-impedance applications.
