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. The LTC6943 can also be driven with an external
CMOS clock.

TYPICAL APPLICATIO
Precision Voltage Controlled Current Source
with Ground Referred Input and Output
5V
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,voltagemultiplicationanddivisionby2,3,4,5,
etc.
The LTC6943 is manufactured using Linear Technology’s
enhanced LTCMOS TM silicon gate process, and it is func-
tionally compatible with the LTC1043.
