LTC6907IS6#TRPBF

LTC®6907 is a micropower, 40KHz to 4MHz resistor set 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 0.65% initial accuracy. The output frequency can be divided by 1, 3 or 10 to span a 100:1 total frequency range, 40KHz to 4MHz. Application includes low cost precision programmable oscillator, rugged, compact micropower replacement for crystal and ceramic oscillators, high shock and vibration environments, portable and battery-powered equipment, PDAs and cellular phones.
