8-Bit and 10-Bit DACs
DESCRIPTION
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 volt-
age interpolation architecture provides excellent linearity
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.
