LTC1043CSW#TRPBF

Specialized ICS Overview

The LTC1043CSW#TRPBF is a monolithic, charge-balanced, dual switched capacitor instrumentation building block manufactured by Analog Devices Inc. It operates from a supply voltage of 3V to 18V and features two independent sections sharing one clock. The device provides ultra-precision DC functions such as differential-to-single-ended conversion, voltage inversion, multiplication, and division without requiring precise external components. It includes an internal oscillator adjustable via an external capacitor or driven by an external CMOS clock up to 5MHz. Packaged in an 18-SOIC (7.50mm width) case with Tape & Reel delivery, it is designed for low power consumption and high common-mode rejection.

Specialized ICS Feature Summary

• Dual precision instrumentation switched capacitor building blocks with break-before-make switching action
• Internal or external clock operation with frequencies up to 5MHz
• Ultra-precision DC functions including voltage inversion, multiplication, and division
• Charge-balanced architecture for minimal charge injection

Specialized ICS Applications

• Instrumentation amplifiers
• Sample-and-hold circuits
• Switched capacitor filters
• Voltage-to-frequency and frequency-to-voltage converters

Specialized ICS Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the Tape & Reel packaging format as indicated in local product fields. Confirm that the component grade matches the required operating temperature range for the application environment. Ensure compatibility with the 18-SOIC surface mount footprint during PCB layout planning.

Specialized ICS Selection Notes

Select this component when high common-mode rejection ratio (CMRR) is required at DC and low frequencies. The internal oscillator simplifies design by reducing external component count, though an external clock can be used for synchronization. Ensure sampling capacitors are non-polarized film types (e.g., Mylar or Polystyrene) to achieve specified performance levels.

Specialized ICS Part Context

This part belongs to the LTC1043 series of dual switched capacitor building blocks. It is distinct from voltage regulators or interface ICs within the same manufacturer's portfolio. The SW package variant indicates a wide 18-lead plastic small outline form factor suitable for surface mount assembly.

Specialized ICS Replacement Considerations

The datasheet identifies the N18 package (18-Lead PDIP) as an alternate source option for the LTC1043. No other direct cross-model substitutes are documented in the provided materials.
