DESCRIPTION
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.
