Product Details

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.
