LTC1664
Micropower Quad
10-Bit DAC
Features Description Tiny: 4 DACs in the Board Space of an SO-8
n Micropower: 59ВµA per DAC Plus
1ВµA Sleep Mode for Extended Battery Life
n Wide 2.7V to 5.5V Supply Range
n Rail-to-Rail Voltage Outputs Drive 1000pF
n Reference Range Includes Supply for Ratiometric
0V to VCC Output
n Reference Input Impedance is Code-Independent
—Eliminates External Reference Buffer
n Individually Addressable DACs
n Differential Nonlinearity: ≤ ±0.75LSB Max
n Pin-Compatible Octal Version Available (LTC1660) The LTCВ®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 59ВµA
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. n Linear Technology’s proprietary, inherently monotonic
voltage interpolation architecture provides excellent linearity while allowing for an exceptionally small external
form factor. …
