Description

The LTC2753 is a family of dual 12-, 14-, and 16-bit multiplying parallel-input, current-output DACs. These DACs operate from a single 2.7V to 5.5V supply and are all guaranteed monotonic over temperature. The LTC2753A-16 provides 16-bit performance (±1LSB INL and DNL) over temperature without any adjustments. These SoftSpan™DACs offer six output ranges—two unipolar and four bipolar—that can be programmed through the parallel interface, or pinstrapped for operation in a single range.The LTC2753 DACs use a bidirectional input/output parallel interface that allows readback of any on-chip register. A power-on reset circuit resets the DAC outputs to 0V when power is initially applied. A logic low on theCLRpin asynchronously clears the DACs 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
