The LTC6906 is a precision programmable oscillator that is versatile, compact and easy-to-use. Micropower operation benefits portable and battery-powered equipment. At 100kHz, 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, 10kHz to 1MHz.
No decoupling capacitor is needed in most cases, yielding an extremely compact 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 (ThinSOT) package.
