    n 12-Lead MSOP Package The LTC®2644 is a family of dual 12-, 10-, and 8-bit PWMto-voltage output DACs with an integrated high accuracy,
    low drift, 10ppm/°C reference in a 12-lead MSOP package. It
    has rail-to-rail output buffers and is guaranteed monotonic. Applications The LTC2644 has a full-scale output of 2.5V using the
    10ppm/°C internal reference. It can operate with an external
    reference, which sets the full-scale output equal to the external reference voltage. Each DAC enters a pin-selectable
    idle state when the PWM input is held unchanged for
    more than 60ms. The part operates from a single 2.7V
    to 5.5V supply and supports PWM input voltages from
    1.71V to 5.5V. n n n n n The LTC2644 measures the period and pulse width of the
    PWM input signals and updates the voltage output DACs
    after each corresponding PWM input rising edge. The ...
