LTC6995IDCB-2#TRPBF

Programmable Timers And Oscillators Overview

The LTC6995IDCB-2#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 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 Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging. Confirm the 'I' grade corresponds to the -40°C to 85°C operating temperature range. Ensure the '-2' designation matches the requirement for an active-low reset input polarity. Cross-reference the DFN-6 package dimensions against the PCB footprint requirements.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-2 variant specifically when an active-low reset signal is required by the system logic. Use Table 1 in the datasheet to determine the correct resistor values for the DIV pin to achieve the desired NDIV and POL bit settings. Calculate RSET based on the target output period and selected NDIV value to ensure frequency accuracy within ±1.5% maximum 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 distinct from other TimerBlox parts like the LTC6990 or LTC6992 due to its extended long-timer capabilities and specific low-frequency oscillator design. The IDCB-2 part number specifies the industrial temperature grade, DFN-6 package, and active-low reset configuration.

Programmable Timers And Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Replacement requires verifying compatibility of reset polarity, package dimensions, and electrical characteristics such as supply voltage range and output drive capability.
