The LTC1662 is an ultralow power, fully buffered voltage output, dual 10-bit digital-to-analog converter (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.

Linear Technology’s 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 DACs without interrupting Sleep mode.

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, VCC = 5V) rail-to-rail outputs.

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 industrial temperature range.

LTC1661/LTC1662 2-Channel, 10-Bit, Micropower DACs

Product Detail

Demonstration circuit 2789A features the LTC®1661/ LTC1662, 2-channel, 10-Bit, micropower DACs in an 8-lead MSOP package. The DC2789A also features an LTC1258-4.1, a lower voltage reference. The LTC1661/ LTC1662 are ultralow power, fully buffered voltage output, dual 10-bit digital-to-analog converters (DACs).

Each LTC1662 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. Each LTC1661 channel draws 30µA.
