LTC6943IGN

开关 IC - 各种 LTC6943 - Micropower, Dual Precision Instrumentation Switched Capacitor Building Block

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.
