Product Details
LTC1043CSW#PBF - Dual Precision Switched-Capacitor Building Block
LTC1043CSW#PBF from Analog Devices is a dual, charge-balanced switched-capacitor instrumentation building block in an 18-lead wide SOIC package, supplied in tubes.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
Two independent switching sections alternately connect external sampling capacitors to input and output nodes. A shared internal oscillator, adjustable with an external capacitor, or an external CMOS clock controls both sections.
Key Advantages
Supports differential-to-single-ended conversion, precision voltage scaling and switched-capacitor signal processing.
Combines two charge-balanced sections and a shared clock in one 18-lead SOIC.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary

Replacement Considerations
LTC1043CSW#TRPBF is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Analog Devices lists the LTC1043CSW#PBF 18-lead wide SOIC order code. The linked #TRPBF variant uses tape-and-reel packaging; compare full ordering and assembly requirements before substitution.
Applications
Implements sampled analog front ends and differential-to-single-ended conversion.
Supports precision voltage inversion, scaling, filtering and sample-and-hold circuits.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
