The LTC1661 integrates two accurate, serially addressable, 10-bit digital-to-analog converters (DACs) in a single tiny MS8 package. Each buffered DAC draws just 60μA total supply current, yet is capable of supplying DC output currents in excess of 5mA and reliably driving capacitive loads up to 1000pF. Sleep mode further reduces total supply current to a negligible 1μA.Proprietary, inherently monotonic voltage interpolation architecture provides excellent linearity while allowing for an exceptionally small external form factor. The double-buffered input logic provides simultaneous update capability and can be used to write to either DAC without interrupting sleep mode.Ultralow supply current, power-saving sleep mode and extremely compact size make the LTC1661 ideal for battery-powered applications, while its straightforward usability, high performance and wide supply range make it an excellent choice as a general purpose converter.For additional outputs and even greater board density, please refer to the LTC1660 micropower octal DAC for 10‑bit applications. For 8-bit applications, please consult the LTC1665 micropower octal DAC.ApplicationsMobile CommunicationsDigitally Controlled Amplifiers and AttenuatorsPortable Battery-Powered InstrumentsAutomatic Calibration for ManufacturingRemote Industrial Devices
