Linear DC1684A-A Demo Board for LTC2758 ADC / DAC

The LinearTechnology LTC®2758 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 and CLR pin both reset the DAC outputs to 0V regardless of output range.

This board is part of Linear Technology's QuickEval system and requires a DC590B companion board.
