The LTC2641CS8-16#PBF is a 16-bit Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and is guaranteed monotonic over-temperature. The LTC2641A-16 provides 16-bit performance (±1LSB INL and ±1LSB DNL) over-temperature. Unbuffered DAC outputs result in low supply current of 120μA and a low offset error of ±1LSB. Both the LTC2641 feature a reference input range of 2V to VDD. VOUT swings from 0V to VREF. The LTC2641 use a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz and can interface directly with optocouplers for applications requiring isolation.
