The LTC
®
1661 integrates two accurate, serially addres-
sable, 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 re-
duces total supply current to a negligible 1µA.
Linear Technology’s proprietary, inherently monotonic
voltage interpolation architecture provides excellent lin-
earity 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.
