LTC1662  
Ultralow Power, Dual  
10-Bit DAC in MSOP  
Features  
Description  
Ultralow Power: 1.5µA (Typ) I per DAC Plus  
The LTC®1662 is an ultralow power, fully buffered voltage  
output,dual10-bitdigital-to-analogconverter(DAC).Each  
DAC channel draws just 1.7µA (typ) total supply-plus-  
reference operating current, yet is capable of supplying  
DC output currents in excess of 1mA and reliably driving  
capacitive loads of up to 1000pF. A programmable sleep  
mode further reduces total operating current to 0.05µA.

With its tiny operating current and exceptionally small  
size, the LTC1662 is ideal for use in the most power-  
constrained products. For most designs, there is no  
perceptible impact on the power budget; the LTC1662  
draws many times less current than even a trimpot,  
while providing buffered, low impedance (0.5Ω typical,

The LTC1662 is pin and software compatible with the  
LTC1661 dual, 60µA 10-bit DAC. It is available in 8-pin  
MSOP and PDIP packages and is specified over the in-  
dustrial temperature range.
