LTC6907 Micropower, 40kHz to 4MHz Resistor Set Oscillator in SOT-23 FEATURES DESCRIPTIO Supply Current: 36A at 400kHz The LTC 6907 is a precision programmable oscillator that 1% Frequency Accuracy (from 0C to 70C) is versatile, compact and easy to use. Micropower opera- Frequency Range: 40kHz to 4MHz tion benefits portable and battery-powered equipment. At One Resistor Sets the Oscillator Frequency 400kHz, the LTC6907 consumes 36A on a 3V supply. 40C to 125C Operating Temperature Range A single resistor programs the oscillator frequency over a Start-Up Time Under 200s at 4MHz 10:1 range with better than 0.65% initial accuracy. The First Cycle After Power-Up is Accurate output frequency can be divided by 1, 3 or 10 to span a 150 CMOS Output Driver 100:1 total frequency range, 40kHz to 4MHz.
