LTC1664 Micropower Quad 10-Bit DAC Features Description n Tiny: 4 DACs in the Board Space of an SO-8 The LTC 1664 integrates four accurate, serially addressable n Micropower: 59A per DAC Plus 10-bit digital-to-analog converters (DACs) in a tiny 16-pin 1A Sleep Mode for Extended Battery Life narrow SSOP package. Each buffered DAC draws just 59A n Wide 2.7V to 5.5V Supply Range total supply current, yet is capable of supplying DC output n Rail-to-Rail Voltage Outputs Drive 1000pF currents in excess of 5mA and reliably driving capacitive n Reference Range Includes Supply for Ratiometric loads of up to 1000pF. Sleep mode further reduces total 0V to V Output supply current to 1A. CC n Reference Input Impedance is Code-Independent Linear Technologys proprietary, inherently monotonic Eliminates External Reference Buffer voltage interpolation architecture provides excellent lin- n Individually Addressable DACs earity while allowing for an exceptionally small external n Differential Nonlinearity: 0.75LSB Max form factor. n Pin-Compatible Octal Version Available (LTC1660) Ultralow supply current, power-saving sleep mode and extremely compact size make the LTC1664 ideal for a battery-powered applications, while its ease of use, high performance and wide supply range make it an excellent n Mobile Communications choice as a general-purpose converter. n Remote Industrial Devices L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Automatic Calibration for Manufacturing Technology Corporation.
