Description

The LTC2751 is a family of 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. They operate from a single 2.7V to 5.5V supply. All parts are guaranteed monotonic over temperature. The LTC2751A-16 provides 16-bit performance (±1LSB INL and DNL) overtemperature without any adjustments. These SoftSpan™DACs offer six output ranges — two unipolar and four bipolar — that can be programmed through the parallel interface, or pin strapped for operation in a single range.These parts use a bidirectional input/output parallel interface that allows read back of any on-chip register. A power-on circuit resets the DAC output to 0V when power is initially applied. A logic low on theCLRpin asynchronously clears the DAC to 0V in any output range.The parts are specified over commercial and industrial temperature ranges.ApplicationsHigh Resolution Offset and Gain AdjustmentProcess Control and Industrial AutomationAutomatic Test EquipmentData Acquisition Systems
