Product Overview

The LTC1662IMS8#PBF is an ultralow power fully buffered voltage output dual 10-bit Digital-to-analog Converter (DAC) with its tiny operating current and exceptionally small size. The DAC channel draws just 1.7µA 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. Linear Technology proprietary, inherently monotonic architecture provides excellent linearity and an exceptionally small external form factor. The double-buffered input logic provides simultaneous update capability and can be used to write to the DAC without interrupting sleep mode. It 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 rail-to-rail outputs.
  • Rail-to-rail voltage outputs drive 1000pF
  • Reference input impedance is code-independent - eliminates external buffers
  • 3-wire serial interface with Schmitt trigger inputs
  • Differential nonlinearity - ±0.75LSB maximum
