The LTC1664IGN#PBF is a serially addressable 10-bit Digital-to-analog Converter (DAC) with micropower quad. The 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. Linear Technology 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.
- 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
- Differential nonlinearity - <=±0.75LSB maximum
