DESCRIPTION
The LTC®6900 is a precision, low power oscillator that is easy to use and occupies very little PC board space. The oscillator frequency is programmed by a single external resistor (RSET). The LTC6900 has been designed for high accuracy operation (≤1.5% frequency error) without the need for external trim components.
