LTC2644 - Dual 12-/10-/8-Bit PWM to VOUT DACs
The LTC®2644 is a family of dual 12-, 10-, and 8-bit PWM-to-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.
The LTC2644 measures the period and pulse width of the PWM input
