DESCRIPTIO

The LTC

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

tion benefits portable and battery-powered equipment. At

100kHz, the LTC6906 consumes 12

µA 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.

The LTC6906 is easily programmed according to this

simple formula:
