DESCRIPTION
The LTC
®
1661 integrates two accurate, serially address-
able, 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 reduces 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.
