Description

General part information

LTC2758 Series

The LTC2758 is a dual 18-bit multiplying serial-input, current-output digital-to-analog converter. LTC2758A provides full 18-bit performance (INL and DNL of ±1LSB maximum) over temperature without any adjustments. 18-bit monotonicity is guaranteed in all performance grades. This SoftSpan™DAC operates from a single 3V to 5V supply and offers six output ranges (up to ±10V) that can be programmed through the 3-wire SPI serial interface or pin-strapped for operation in a single range.Any on-chip register (including DAC output-range settings) can be read for verification in just one instruction cycle; and if you change register content, the altered register will be automatically read back during the next instruction cycle.Voltage-controlled offset and gain adjustments are also provided; and the power-on reset circuit andCLRpin both reset the DAC outputs to 0V regardless of output range.ApplicationsInstrumentationMedical DevicesAutomatic Test EquipmentProcess Control and Industrial Automation
