LTC6995HS6-1#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6995HS6-1#WTRMPBF is a silicon oscillator from the TimerBlox family, designed for long-duration timing events. It features a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz). The device operates on a single supply voltage between 2.25V and 5.5V with a typical supply current ranging from 55µA to 80µA depending on the clock period. Frequency accuracy is specified at ±1.5% maximum over temperature. The output provides a 50% duty cycle square wave capable of sourcing or sinking 20mA. It includes an active-high reset input and is housed in a 6-lead TSOT-23 package.
