FEATURES  
DESCRIPTIO  
The LTC®6943 is a monolithic, charge-balanced, dual  
switched capacitor instrumentation building block. A pair  
of switches alternately connects an external capacitor to  
an input voltage and then connects the charged capacitor  
across an output port. The internal switches have a  
break-before-make action. An internal clock is provided  
and its frequency can be adjusted with an external  
capacitor.TheLTC6943canalsobedrivenwithanexternal  
CMOS clock.  
■
Low Power, IS = 60µA(Max)  
■
Robust, Latch Up Proof  
■
Instrumentation Front End with 120dB CMRR  
■
Precise, Charge-Balanced Switching  
■
Operates from 5V to 18V  
■
Internal or External Clock  
■
Operates up to 5MHz Clock Rate  
■
Two Independent Sections with One Clock  
■
Tiny SSOP-16 Package  
U
The LTC6943, when used with low clock frequencies,  
provides ultra precision DC functions without requiring  
precise external components. Such functions are  
differential voltage to single-ended conversion, voltage  
inversion, voltage multiplication and division by 2, 3, 4, 5,  
etc.  
APPLICATIO S

Current Sources  
■
■
The LTC6943 is manufactured using Linear Technology’s  
enhanced LTCMOSTM silicon gate process, and it is func-  
tionally compatible with the LTC1043.
