LTC6906CS6#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6906CS6#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 of 1, 3, or 10. The device operates on a single supply voltage between 2.25V and 3.6V. At 100kHz, it consumes approximately 12μA. It features less than 0.65% frequency accuracy over the commercial temperature range (0°C to 70°C). The output is CMOS with a 150Ω driver resistance. No external decoupling capacitor is required for loads under 50pF due to internal filtering. It is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify the 'C' suffix indicates the commercial temperature grade (0°C to 70°C). Confirm the '#TRMPBF' suffix denotes tape and reel packaging with lead-free finish. Ensure the application supply voltage does not exceed 3.6V without implementing the recommended RC filter circuit described in the datasheet for higher voltages.

Programmable Timers And Oscillators Selection Notes

Select this part when low power consumption is critical and a wide frequency range is needed. Use the DIV pin to adjust the master oscillator frequency for optimal power efficiency. For frequencies above 3.6V operation, ensure an external RC filter is placed within 1cm of the V+ pin. Consider the 'I' or 'H' suffix variants if extended temperature ranges are required.
