The LTC2642ACMS-16#PBF is a 16-bit un-buffered voltage-output 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 over temperature. Un-buffered DAC outputs result in low supply current of 120μA and a low offset error of ±1LSB. It features a reference input range of 2V to VDD. VOUT swings from 0V to VREF. For bipolar operation, the LTC2642 includes matched scaling resistors for use with an external precision op amp, generating a ±VREF output swing at RFB. It uses 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. A power-on reset circuit clears the LTC2642 DAC output to mid-scale when power is initially applied. A logic low on the CLR pin asynchronously clears the DAC to mid-scale.
