DESCRIPTION
Dual Serial 18-Bit
SoftSpan IOUT DACs
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 set-
tings) 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.
