LTC1661 - Micropower Dual 10-Bit DAC

General Description

The LTC®1661 integrates two accurate, serially addressable, 10-bit digital-to-analog converters (DACs) in a single tiny MS8 package.

Key Features

  • n Tiny: Two 10-Bit DACs in an 8-Lead MSOP.
  • Half the Board Space of an SO-8 n Micropower: 60µA per DAC Sleep Mode: 1µA for Extended Battery Life n Rail-to-Rail Voltage Outputs Drive 1000pF n Wide 2.7V to 5.5V Supply Range n Double Buffered for Independent or Simultaneous DAC Updates n Reference Range Includes Supply for Ratiometric 0V-to-VCC Output n Reference Input Has Constant Impedance over All Codes (260kΩ Typ).
  • Eliminates External Buffers n 3-Wire Serial Interface with Schmitt.
