DESCRIPTION
Quad 12-/16-Bit
SoftSpan IOUT DACs
The LTC2754 is a family of quad 12- and 16-bit multiplying
serial-input, current-output digital-to-analog converters.
They operate from a single 3V to 5V supply and are guar-
anteed monotonic over temperature. The LTC2754A-16
provides full 16-bit performance (±1LSB INL and DNL,
max) over temperature without any adjustments. These
SoftSpan DACs offer six output ranges (up to ±10V) that
can be programmed through the 3-wire SPI serial interface,
or pinstrapped for operation in a single range.
The content of any on-chip register (including DAC out-
put-range settings) can be veried in just one instruction
cycle; and if you change any register, that 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.
