LTC2644 Datasheet Dual 12-/10-/8-bit Pwm To Vout Dacs

Manufacturer: Analog Devices

General Description

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 signals and updates the voltage output DACs after each corresponding PWM input rising edge.
