Product Details

The LTC6906 is a precision programmable oscillator that is versatile, compact and easy-to-use. Micropower 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.  Contact LTC Marketing for a version of the part with a shutdown feature or lower frequency operation.

The LTC6906 is available in the 6-lead SOT-23 (ThinSOT) package.

APPLICATIONS

  • Low Cost Precision Programmable Oscillator
  • Rugged, Compact Micropower Replacement for Crystal and Ceramic Oscillators
  • High Shock and Vibration Environments
  • Portable and Battery-Powered Equipment
  • PDAs and Cellular Phones
