LTC6907 Micropower, 40kHz to 4MHz Resistor Set Oscillator in SOT-23

The LTC®6907 is a precision programmable oscillator that is versatile, compact and easy to use. Micropower operation benefits portable and battery-powered equipment. At 400kHz, the LTC6907 consumes 36µA on a 3V supply.

A single resistor programs the oscillator frequency over a 10:1 range with better than 0.5% initial accuracy. The output frequency can be divided by 1, 3 or 10 to span a 100:1 total frequency range, 40kHz to 4MHz.

The LTC6907 is easily programmed according to this simple formula:

fout = 4MHz / N * (50k/Rset) N = {10 DIV Pin = V+, 3 DIV Pin = Open, 1 DIV Pin = GND}

The LTC6907 is available in the 6-lead SOT-23 (ThinSOT) package. Contact LTC Marketing for a version of the part with a shutdown feature or lower frequency operation
