Features Description
Micropower Quad
10-Bit DAC
The LTC
®
1664 integrates four accurate, serially addressable
10-bit digital-to-analog converters (DACs) in a tiny 16-pin
narrow SSOP package. Each buffered DAC draws just 59µA
total supply current, yet is capable of supplying DC output
currents in excess of 5mA and reliably driving capacitive
loads of up 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 LTC1664 ideal for
battery-powered applications, while its ease of use, high
performance and wide supply range make it an excellent
choice as a general-purpose converter.
