Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with the narrow 16-lead SOIC footprint during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad op amp topology is required alongside tight offset voltage matching and low bias currents. The narrow surface mount package offers space efficiency compared to wide packages. Verify that the application environment falls within the specified operating temperature range for the selected grade.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1112/LT1114 family of low power precision amplifiers. The LT1114 provides four independent amplifiers in a single package, whereas the LT1112 provides two. Both families share similar electrical characteristics and are designed to replace older precision op amps while offering improved price/performance ratios.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Pin-compatible replacements include the LT1112 for dual-channel requirements. Direct substitutes for other manufacturers' parts require verification of pinout alignment and electrical parameter margins.
