External Capacitor

An internal or external clock programs the filter''s cutoff frequency. The clock-to-cutoff frequency ratio is 100:1. In the absence of an external clock, the LTC1063''s internal precision oscillator can be used. An external resistor and capacitor set the device''s internal clock frequency (Figure 476.1). The internal oscillator output is

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
