DESCRIPTIO

The LTC

is versatile, compact and easy to use. Micropower opera-

tion benefits portable and battery-powered equipment. At

400kHz, the LTC6907 consumes 36

µA 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.

The LTC6907 is easily programmed according to this

simple formula:
