LTC1665/LTC1660
Micropower Octal
8-Bit and 10-Bit DACs
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 56
A 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 1
A.
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.
