Features and Benefits
- Tiny: 4 DACs in the Board Space of an SO-8
- Micropower: 59µA per DAC Plus 1µA Sleep Mode for Extended Battery Life
- Wide 2.7V to 5.5V Supply Range
- Rail-to-Rail Voltage Outputs Drive 1000pF
- Reference Range Includes Supply for Ratiometric 0V to VCC Output
- Reference Input Impedance is Code-Independent —Eliminates External Reference Buffer
- Individually Addressable DACs
- Differential Nonlinearity: ≤ ±0.75LSB Max
- Pin-Compatible Octal Version Available (LTC1660)
The LTC1664 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.
Proprietary, inherently monotonic voltage interpolation architecture provides excellent linearity while allowing for an exceptionally small external form factor.
Ultralow supply current, power-saving Sleep mode and extremely compact size make the LTC1664 ideal for battery-powered applications, while its ease of use, high performance and wide supply range make it an excellent choice as a general-purpose converter.

Evaluation Kits (1)
Demonstration circuit 2795 features the LTC®1660/ LTC1665 and LTC1664. The 8-bit LTC1665 and 10-bit LTC1660 integrate eight accurate, serially addressable digital-to-analog converters (DACs) in tiny 16-pin narrow SSOP packages. The LTC1664 is a 10-bit quad DAC.
Each buffered DAC draws just 56μA total supply current yet is capable of supplying DC output currents in excess of 5mA and reliably driving capacitive loads to 1000pF. Sleep mode further reduces total supply current to 1μA.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
