The LTC1662 is an ultralow power, fully buffered voltage output, dual 10-bit digital-to-analog converter (DAC). Each DAC draws just 1.7A (typ) total supply-plusreference operating current, yet is capable of supplying DC output currents in excess of 1mA and reliably driving capacitive loads of up to 1000pF. A programmable Sleep mode further reduces total operating current to a negligible 0.05A. Linear Technology's 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. With its ultralow operating current and exceptionally small size, the LTC1662 is ideal for use in batterypowered products. The LTC1662 is pin- and software-compatible with the LTC1661 micropower dual 10-bit DAC. It is available in 8-pin MSOP and PDIP packages and is specified over the industrial temperature range.
