n 48-Pin 7mm × 7mm LQFP Package The 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. n Applications Any on-chip register (including DAC output-range settings) can be read for verification in just one instruction …
