LT1801CS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1801CS8#PBF is a dual, low power, high speed rail-to-rail input and output precision operational amplifier manufactured by Analog Devices Inc. It operates on single or split supplies ranging from 2.3V to 12.6V. Key electrical specifications include an 80MHz gain bandwidth product, a typical slew rate of 25V/µs, and a maximum input offset voltage of 350µV. The device features a maximum supply current of 2mA per amplifier and supports an output short-circuit current of up to 45mA. It is housed in an 8-lead plastic SO package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging when ordering. Confirm the 'C' grade temperature range meets application requirements, as it is guaranteed functional over -40°C to 85°C but tested from 0°C to 70°C. Ensure the 8-lead SOIC footprint matches the PCB design. Check for RoHS compliance documentation if required by local regulations.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring simultaneous rail-to-rail I/O and high-speed performance under low voltage constraints. It serves as a suitable replacement for older op amps where improved input/output range is needed. Consider thermal dissipation limits in the SO-8 package when driving heavy loads. Verify that the 80MHz bandwidth aligns with the system's signal frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1801/LT1802 family of dual/quad precision op amps. The LT1801 is the dual version available in MSOP, SO-8, and DFN packages, while the LT1802 is the quad version in a 14-lead SO package. The series is designed to offer reduced supply current and lower input offset voltage compared to comparable bandwidth devices.
