LTC1665/LTC1660 Micropower Octal 8-Bit and 10-Bit DACs FEATURES DESCRIPTION n Tiny: 8 DACs in the Board Space of an SO-8 The 8-bit LTC 1665 and 10-bit LTC1660 integrate eight n Micropower: 56A per DAC Plus accurate, serially addressable digital-to-analog convert- 1A Sleep Mode for Extended Battery Life ers (DACs) in tiny 16-pin narrow SSOP packages. Each n Pin Compatible 8-Bit LTC1665 and 10-Bit LTC1660 buffered DAC draws just 56A total supply current, yet n Wide 2.7V to 5.5V Supply Range is capable of supplying DC output currents in excess n Rail-to-Rail Voltage Outputs Drive 1000pF of 5mA and reliably driving capacitive loads to 1000pF. n Reference Range Includes Supply for Ratiometric Sleep mode further reduces total supply current to 1A. 0V-to-V Output CC Linear Technologys proprietary, inherently monotonic volt- n Reference Input Impedance is Constant age interpolation architecture provides excellent linearity Eliminates External Buffer while allowing for an exceptionally small external form factor. APPLICATIONS Ultralow supply current, power-saving Sleep mode and extremely compact size make the LTC1665 and LTC1660 n Mobile Communications ideal for battery-powered applications, while their ease n Remote Industrial Devices of use, high performance and wide supply range make n Automatic Calibration for Manufacturing them excellent choices as general purpose converters. n Portable Battery-Powered Instruments L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Trim/Adjust Applications Technology Corporation.
