    n 16-Lead MSOP Package
    n n n n n n The LTC2645 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
    DAC outputs update and settle to 12-bit accuracy within
    8µs typically and are capable of sourcing and sinking up
    to 5mA (3V) or 10mA (5V), eliminating voltage ripple and
    replacing slow analog filters and buffer amplifiers.
    The LTC2645 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 ...
