The LTC®6906 is a precision programmable oscillator that is versatile, pact and easy to use. Micropower operation benefits portable and battery-powered equipment. At 100k Hz, the LTC6906 consumes 12μA on a 3.3V 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, 10k Hz to 1MHz.
The LTC6906 is easily programmed according to this simple formula:

No decoupling capacitor is needed in most cases, yielding an extremely pact solution occupying less than 20mm2. Contact LTC Marketing for a version of the part with a shutdown feature or lower frequency operation.
The LTC6906 is available in the 6-lead SOT-23 (Thin SOT) package.
