The LTC ? 1043 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 LTC1043 can also be driven with an external

CMOS clock.
The LTC1043, 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. The LTC1043 can also be used for precise V–F and
F–V circuits without trimming, and it is also a building
block for switched capacitor filters, oscillators and
modulators.
The LTC1043 is manufactured using Linear Technology’s
enhanced LTCMOS TM silicon gate process.
