The LTC
®
6906 is a precision programmable oscillator that
is versatile, compact and easy-to-use. Micropower opera-
tion 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.
The LTC6906 is easily programmed according to this
simple formula:
