LTC2645 Datasheet - Linear Technology

LTC2645 Quad 12-/10-/8-Bit PWM to VOUT DACs

The LTC®2645 is a family of quad 12-, 10-, and 8-bit PWM-to-voltage output DACs with an integrated high accuracy, low drift, 10ppm/°C reference in a 16-lead MSOP package. It has rail-to-rail output buffers and is guaranteed monotonic. The LTC2645 measures the period and pulse width of the PWM input .
