LTC6995CDCB-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995CDCB-1#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 output frequency is set by a single resistor RSET and an internal divider NDIV. Key electrical parameters include a supply voltage range of 2.25V to 5.5V, supply current between 55µA and 80µA depending on configuration, and maximum frequency error of ±1.5%. It operates within a commercial temperature range of 0°C to 70°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging. Confirm the CDCB designation corresponds to the 6-lead DFN package and the C grade specifies the 0°C to 70°C operating temperature range. Ensure compatibility with active-high reset requirements inherent to the -1 variant.

Programmable Timers And Oscillators Selection Notes

Select this part for applications requiring precise low-frequency oscillation without external crystals. Use the DIV pin resistor network to set the division ratio NDIV and output polarity. Ensure RSET tolerance is within 0.5% for optimal accuracy. Verify that the required period falls within the 1.024ms to 9.54-hour window defined by the master oscillator and divider settings.

Programmable Timers And Oscillators Part Context

This component belongs to the Analog Devices TimerBlox family of versatile silicon timing devices. The LTC6995 series includes variants with different reset polarities (-1 for active high, -2 for active low) and temperature grades (C, I, H, MP). The DCB package denotes the 2mm x 3mm plastic DFN form factor.

Programmable Timers And Oscillators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider checking for other TimerBlox family members like the LTC6990 or LTC6992 if frequency ranges or package types differ significantly.
