LTC6995IDCB-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6995IDCB-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 external resistor (RSET) connected between the SET and GND pins. An internal 4-bit A/D converter on the DIV pin selects one of eight divider settings (NDIV = 1 to 221) and determines output polarity. The device operates on a single supply voltage of 2.25V to 5.5V with low current consumption ranging from 55µA to 80µA. It provides an active-high reset input for the -1 variant.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates Tape and Reel (Mini) packaging when ordering. Confirm the temperature grade 'I' corresponds to the –40°C to 85°C specified operating range. Ensure the '-1' designation matches the requirement for an active-high reset input polarity.

Programmable Timers And Oscillators Selection Notes

Select the LTC6995-1 variant for active-high reset logic. Calculate RSET based on the desired output period and selected NDIV value from Table 1 in the datasheet. Use precision resistors for RSET to maintain frequency accuracy within ±1.5%. Ensure DIV pin voltage tracks V+ accurately for correct divider selection.
