Product Overview

The LTC2644CMS-L8#PBF is a dual 8-bit PWM-to-voltage output Digital-to-analog Converter (DAC) with an integrated high accuracy, low-drift, 10ppm/°C reference. It has rail-to-rail out-put buffers and is guaranteed monotonic. The LTC2644 measures the period and pulse width of the PWM input signals and updates the voltage output DAC 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 5/10mA, eliminating voltage ripple and replacing slow analog filters and buffer amplifiers. 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. The DAC enters a pin-selectable idle state when the PWM input is held unchanged for more than 60ms. The part operates from a single 2.7 to 5.5V supply and supports PWM input voltages from 1.71 to 5.5V.
  • No latency PWM-to-voltage conversion
  • Voltage output updates and settles within 8µs
