DESCRIPTIO
The 8-bit LTC
®
1665 and 10-bit LTC1660 integrate eight
accurate, serially addressable digital-to-analog convert-
ers (DACs) in tiny 16-pin narrow SSOP packages. Each
buffered DAC draws just 56µA total supply current, yet is
capable of supplying DC output currents in excess of
5mA and reliably driving capacitive loads to 1000pF.
Sleep mode further reduces total supply current to 1µA.
Linear Technology’s proprietary, inherently monotonic
voltage interpolation architecture provides excellent lin-
earity while allowing for an exceptionally small external
form factor.
Ultralow supply current, power-saving Sleep mode and
extremely compact size make the LTC1665 and LTC1660
ideal for battery-powered applications, while their ease of
use, high performance and wide supply range make them
excellent choices as general purpose converters.
