LT1369CS#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1369CS#TRPBF is a quad precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on supply voltages ranging from 1.8V to 36V. The device exhibits a typical input offset voltage of 150µV and a gain-bandwidth product of 400kHz. It requires a 0.1µF output capacitor for stability, which enhances supply rejection and reduces high-frequency noise. Packaged in a 14-lead plastic SOIC, it is designed for applications requiring high precision and wide dynamic range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the 14-lead plastic SO package matches the design requirements. Ensure the application circuit includes the mandatory 0.1µF output capacitor as specified for the LT1369 variant to maintain stability and performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad configuration with rail-to-rail swing is required alongside precision DC characteristics. The requirement for an external 0.1µF output capacitor distinguishes it from the LT1367, offering better power supply rejection and lower output impedance at high frequencies. It serves as a suitable replacement for standard op amps where improved input/output range is needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1366/LT1367/LT1368/LT1369 family of dual and quad bipolar op amps manufactured by Analog Devices. The LT1369 specifically denotes the quad version with compensation that mandates a 0.1µF load capacitance. This family is designed to plug into standard op amp sockets while providing enhanced precision and wider signal ranges.

Instrumentation, Op Amps, Buffer Amps FAQ

Why does the LT1369 require a 0.1µF output capacitor?

The LT1369 has specific compensation that requires a 0.1µF output capacitor. This capacitor improves the amplifier’s supply rejection and reduces output impedance at high frequencies, filtering out high-frequency noise beneficial for driving A/D converters.

What is the maximum supply voltage for the LT1369?

The total supply voltage (V+ to V–) can reach up to 36V. The device is specified for operation with 3V, 5V, and ±15V supplies.
