LTC6995HDCB-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995HDCB-2#TRMPBF 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 uses a single resistor, RSET, to program the internal master oscillator frequency, while an internal divider, NDIV, sets the output clock period. It includes a reset function to stop oscillation and clear dividers. The LTC6995-2 variant has an active-low reset input. 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 #TRMPBF indicates mini tape and reel packaging when ordering. Confirm the temperature grade 'H' corresponds to the -40°C to 125°C operating range required for the application. Ensure the DCB package dimensions match the PCB footprint design constraints.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 version specifically for applications requiring an active-low reset signal. Use Table 1 in the datasheet to determine the correct resistor values for the DIV pin to achieve the desired NDIV and output polarity settings. Calculate RSET based on the target output period and selected NDIV value to ensure frequency accuracy within ±1.5%.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The HDCB suffix denotes the 6-lead (2mm × 3mm) Plastic DFN package. The '#TRMPBF' suffix specifies lead-free finish and mini tape and reel packaging. The '-2' designation distinguishes it from the '-1' variant by providing an active-low reset input instead of active-high.
