LT1884ACS8#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1884ACS8#TRPBF is a dual precision operational amplifier from Analog Devices, housed in an 8-lead plastic small outline (SOIC) package. It features rail-to-rail output swing and operates on supply voltages between 2.7V and 36V. The device provides high accuracy with input offset voltage trimmed to less than 50mV for the A grade and maintains low drift over temperature. Input bias currents are ultralow at a maximum of 400pA. Key performance metrics include a slew rate of 1V/ms, a gain-bandwidth product of 2MHz, and a large-signal voltage gain of 1 million minimum.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'A' grade designation corresponds to the tighter offset voltage specifications of 50mV maximum. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements. Cross-reference the manufacturer part number directly with official Analog Devices documentation to validate authenticity and revision status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring both high DC precision and AC speed. The combination of picoamp input bias currents and rail-to-rail outputs makes it suitable for low-voltage single-supply designs. Consider the 1mA supply current per amplifier for power-constrained environments. Evaluate the 2MHz bandwidth against signal frequency requirements to ensure adequate settling time.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1884/LT1885 family of dual and quad precision operational amplifiers. The LT1884 variant specifically contains two independent amplifiers within a standard 8-pin package configuration. This family bridges the gap between traditional precision amplifiers and faster general-purpose devices, offering superior response times while maintaining high input accuracy.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the input common mode voltage range?

The input stage operates between VEE + 0.8V and VCC – 0.9V. Exceeding this range causes the gain to drop to zero without gain reversal.

How does the device handle capacitive loads?

It can drive capacitive loads up to 300pF when configured for unity gain. Driving capability increases in higher gain configurations or by decoupling capacitance with a small series resistance.
