LTC6906IS6#PBF

LINEAR TECHNOLOGY  LTC6906IS6#PBF  芯片, 振荡器, 10KHz - 1MHz, SMD

The is a micropower 10kHz to 1MHz Resistor Set Oscillator featuring versatile, compact and easy-to-use. Micro power operation 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. No decoupling capacitor is needed in most cases, yielding an extremely compact solution occupying less than 20mm². The period and frequency are determined exclusively by RSET and the precision internal capacitor. Importantly, the value of VSET is immaterial and the LTC6906 maintains its accuracy even though VSET is not a precision reference voltage.
