LTC6943中文资料微功率、精准仪表双开关电容器单元式部件数据手册ADI规格书

描述 Description

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. 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.

The LTC6943 is manufactured using Linear Technology’s enhanced LTCMOSTM silicon gate process, and it is functionally compatible with the LTC1043.
