Overview
The LTC6900CS5#TRPBF, produced by Analog Devices Inc., is a precision, low-power oscillator designed for high accuracy and ease of use. It occupies minimal PC board space and is packaged in a 5-lead ThinSOT (TSOT-23) package. The oscillator frequency is programmable using a single external resistor, eliminating the need for external trim components. It operates with a single 2.7V to 5.5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. This component is ideal for applications requiring low power consumption and high frequency accuracy.
