LTC6995CS6-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995CS6-1#TRPBF 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 output clock period is determined by an internal master oscillator and a programmable frequency divider (NDIV) with eight settings from 1 to 221. Frequency is programmed via a single resistor (RSET) on the SET pin. The device includes a reset function to stop oscillation and clear dividers. It operates on a single supply voltage of 2.25V to 5.5V with a supply current ranging from 55µA to 80µA depending on the clock period.

Programmable Timers And Oscillators Feature Summary

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with a standard factory quantity. Confirm the 'C' grade designation corresponds to the 0°C to 70°C specified temperature range for this particular part number. Ensure the ordering information matches the active-low or active-high reset requirement, as the -1 suffix denotes active-high reset functionality.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995CS6-1 variant when an active-high reset signal is required. The 'C' suffix specifies commercial temperature operation (0°C to 70°C). For wider temperature ranges, consider the 'I' (-40°C to 85°C) or 'H' (-40°C to 125°C) grades. The S6 package denotes the 6-lead TSOT-23 form factor. Calculate RSET based on the desired period and NDIV setting to ensure accuracy within ±1.5% maximum frequency error.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The LTC6995 series is specifically engineered for applications requiring precise, long-duration timing intervals that are difficult to achieve with standard microcontrollers or discrete components. It serves as a low-cost, low-power alternative to RTCs or complex timer ICs for simple periodic tasks.
