The LTC6995CDCB-1#PBF from Analog Devices is part of the TimerBlox family, specifically designed as a long timer and low frequency oscillator. This device is intended for applications requiring extended timing durations, with a programmable period range spanning from 1.024ms to 9.54 hours (equivalent to 29.1µHz to 977Hz).
Key electrical characteristics include a wide supply voltage range of 2.25V to 5.5V, a low supply current consumption of 55µA to 80µA, and a fast start-up time of 500µs. The oscillator features a maximum frequency error of less than 1.5% and a CMOS output driver capable of sourcing or sinking 20mA. The operating temperature range is from -55°C to 125°C.
Configuration is achieved using a single resistor (RSET) to program the master oscillator frequency, with an internal frequency divider (NDIV) offering eight settings from 1 to 221. The output is a 50% duty cycle square wave. A reset function is integrated to stop the oscillator and clear internal dividers, useful for power-on reset and watchdog timer applications. The LTC6995-1 version features an active-high reset input.
This component is available in low-profile SOT-23 (ThinSOT) and 2mm x 3mm DFN packages, both suitable for surface mount assembly.
