Linear Technology LT1678
the LT1678), generating a ±VREF output swing at RFB. The LTC2641/LTC2642 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. These DACs are all specified over the commercial and industrial ranges.| Part No. | LT1678 |

DESCRIPTION
The LTC®2641/LTC2642 are families of 16-, 14- and 12-bit unbuffered voltage output DACs. These DACs operate from a single 2.7V to 5.5V supply and are guaranteed monotonic over temperature. The LTC2641-16/LTC2642-16 provide 16-bit performance (±2LSB 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 and LTC2642 feature 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 (such as A power-on reset circuit clears the LTC2641’s DAC output to zero scale and the LTC2642’s DAC output to midscale when power is initially applied. A logic low on the ⎯C⎯L⎯R pin asynchronously clears the DAC to zero scale (LTC2641) or midscale (LTC2642). , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
