LTC1662
Description
The LTC®1662 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-plusreference operating current, yet is capable of supplying DC output currents in excess of 1mA and reliably driving capacitive loads of up to 1000pF.
Key Features
- Ultralow Power: 1.5µA (Typ) ICC per DAC Plus 0.05µA Sleep Mode for Extended Battery Life
- Tiny: Two 10-Bit DACs in an 8-Lead MSOP- Half the Size of an SO-8
- Wide 2.7V to 5.5V Supply Range
- Double Buffered for Simultaneous DAC Updates
- Rail-to-Rail Voltage Outputs Drive 1000pF
- Reference Range Includes Supply for Ratiometric 0V to VCC Output
- Reference Input Impedance Is Code-Independent (7.1MΩ Typ)-Eliminates External Buffers
- 3-Wire Serial Interface with Schmitt Trigger Inputs
- Differential Nonlinearity: ±0.75LSB Max
