LTC2645 PWM-to-VOUT DACs

Analog Devices introduces its LTC2645 quad 12-, 10-, 8-bit PWM-to-VOUT DACs with 10 ppm/°C reference

Image of Analog Devices' LTC2645 PWM-to-VOUT DACsAnalog Devices' LTCR2645 is a family of quad 12-, 10-, and 8-bit PWM-to-voltage output DACs with an integrated high accuracy, low drift, 10 ppm/°C reference in a 16-lead MSOP package. It has rail-to-rail output buffers and is guaranteed monotonic. The LTC2645 has a full-scale output of 2.5 V using the 10 ppm/°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 idle state when the PWM input is held unchanged for more than 60 ms. The part operates from a single 2.7 V to 5.5 V supply and supports PWM input voltages from 1.71 V to 5.5 V.

Features
  • No latency PWM-to-voltage conversion
  • Voltage output updates and settles within 8 μs
  • 100 kHz to 30 Hz PWM input frequency
  • ±2.5 LSB max INL; ±1 LSB max DNL (LTC2645-12)
  • Guaranteed monotonic
  • Pin-selectable internal or external reference
  • 2.7 V to 5.5 V supply range
  • 1.71 V to 5.5 V input voltage range
  • Low power: 2.7 mA at 3 V, <1 μA power-down
  • Guaranteed operation from -40°C to 125°C
  • 16-lead MSOP package
Applications
  • Digital calibrations
  • Trimming and adjustments
  • Level settings
  • Process control and industrial automation
  • Instrumentation
  • Automotive
