LTC1661
Description
The LTC®1661 integrates two accurate, serially addressable, 10-bit digital-to-analog converters (DACs) in a single tiny MS8 package. Each buffered DAC draws just 60µA total supply current, yet is capable of supplying DC output currents in excess of 5mA and reliably driving capacitive loads up to 1000pF.
Key Features
- Tiny: Two 10-Bit DACs in an 8-Lead MSOP- Half the Board Space of an SO-8
- Micropower: 60µA per DAC Sleep Mode: 1µA for Extended Battery Life
- Rail-to-Rail Voltage Outputs Drive 1000pF
- Wide 2.7V to 5.5V Supply Range
- Double Buffered for Independent or Simultaneous DAC Updates
- Reference Range Includes Supply for Ratiometric 0V-to-VCC Output
- Reference Input Has Constant Impedance over All Codes (260kΩ Typ)-Eliminates External Buffers
- 3-Wire Serial Interface with Schmitt Trigger Inputs
- Differential Nonlinearity: ≤±0.75LSB Max
