LTC6906IS6#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6906IS6#TRMPBF is a micropower, resistor-set silicon oscillator from Analog Devices. It generates frequencies from 10kHz to 1MHz using a single external resistor (RSET) and an internal divider ratio selectable via the DIV pin. The device operates on a single supply of 2.25V to 3.6V, consuming as little as 10μA at 100kHz. It features high initial accuracy with less than 0.65% drift over temperature and requires no external decoupling capacitor for loads under 50pF. Packaged in a low-profile 6-lead TSOT-23, it serves as a compact replacement for crystal oscillators in portable applications.

Programmable Timers And Oscillators Feature Summary

• Frequency Range: 10kHz to 1MHz set by one resistor
• Micropower Operation: 10μA to 78μA depending on frequency
• High Accuracy: <0.65% frequency error from -40°C to 85°C
• No Decoupling Required: Internal filtering supports loads <50pF

Programmable Timers And Oscillators Applications

• Portable and battery-powered equipment
• PDAs and cellular phones
• High shock and vibration environments

Programmable Timers And Oscillators Procurement Notes

Verify the IS6 suffix indicates the industrial temperature range (-40°C to 85°C) and the TRMPBF suffix denotes tape and reel packaging. Confirm that the application circuit adheres to the specified 2.25V to 3.6V supply voltage limits for this specific grade. Ensure RSET values remain within the 100kΩ to 1MΩ range for optimal performance.

Programmable Timers And Oscillators Selection Notes

Select the IS6 variant for operation between -40°C and 85°C; use HS6 for -40°C to 125°C or CS6 for 0°C to 70°C. Choose the divider ratio (N=1, 3, or 10) based on the required output frequency to minimize power consumption. For frequencies above 3.6V operation, an external RC filter is mandatory. Use precision resistors for best accuracy.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of silicon timing devices. It is functionally similar to the LTC6900 and LTC6905 but offers a lower frequency range optimized for micropower applications. It replaces discrete crystal oscillators in space-constrained designs.
