LT1885CS#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1885CS#PBF is a quad precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing and operates on supply voltages between 2.7V and 36V. The device provides an input offset voltage of up to 150mV over the full temperature range, with a maximum input bias current of 1400pA. Key electrical parameters include a gain-bandwidth product of 2.2MHz, a slew rate of 1V/ms, and a supply current of less than 1mA per amplifier. It is housed in a standard 14-lead plastic SO package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output capability for low voltage single-supply operation
• Ultra-low input bias currents suitable for high impedance sources
• High open-loop voltage gain exceeding one million minimum
• Input fault protection against sustained differential voltages

Instrumentation, Op Amps, Buffer Amps Applications

• Thermocouple amplifiers
• Bridge transducer conditioners
• Instrumentation amplifiers
• Battery-powered systems
• Precision integrators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the S package designation matches the required 14-lead narrow SOIC footprint for PCB layout compatibility. Ensure the operating temperature range requirements align with the specified -40°C to 85°C limits for industrial applications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high input precision and wide output voltage swing are required simultaneously. It serves as a direct upgrade for legacy precision amplifiers lacking rail-to-rail performance. Consider the 14-pin package constraint if replacing dual-channel alternatives like the LT1884.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1884/LT1885 family of dual and quad precision op amps. It shares core specifications with the LT1884 but integrates four independent channels into a single 14-lead package. The series is designed to bridge the gap between traditional precision amplifiers and modern low-voltage rail-to-rail devices.
