Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the S8 suffix indicates the 8-lead Plastic Small Outline package and #TRPBF confirms tape and reel packaging. Confirm the operating temperature range matches the C grade specification (0°C to 70°C). Ensure lead-free finish compliance aligns with project requirements. Cross-reference pinouts against existing PCB layouts to ensure compatibility.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both low offset voltage and high slew rate are required. The LT1056 offers higher speed than the LT1055 but consumes more power. Consider the SO package for surface mount applications. Evaluate noise performance if low-frequency signal integrity is critical. Verify supply voltage constraints fit within the ±20V absolute maximum rating.

Instrumentation, Op Amps, Buffer Amps Part Context

Part of the LT1055/LT1056 family of JFET input op amps. Differentiated from the LT1055 by higher power dissipation enabling greater speed. Replaces older hybrid FET designs. Compatible with industry-standard DIP sockets. Designed for applications requiring picoampere bias currents and microvolt accuracy.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the LT1056 exhibit phase reversal?

No, the LT1056 includes unique phase reversal protection circuitry that prevents output lock-up when the negative common mode limit is exceeded.

How does the LT1056 differ from the LT1055?

The LT1056 dissipates more power to achieve a higher slew rate (16V/µs vs 10V/µs) and wider bandwidth (6.5MHz vs 5MHz), while maintaining similar precision characteristics.
