Serial 16-Bit
Multiplying DACs
TheLTC1595/LTC1596/LTC1596-1areserialinput,16-bit
multiplying current output DACs. The LTC1595 is pin and
hardware compatible with the 12-bit DAC8043 and comes
in 8-pin PDIP and SO packages. The LTC1596 is pin and
hardware compatible with the 12-bit DAC8143/AD7543
and comes in the 16-pin SO wide package.
Both are specified over the industrial temperature range.
Sensitivity of INL to op amp VOS is reduced by five times
compared to the industry standard 12-bit DACs, so most
systems can be easily upgraded to true 16-bit resolution
and linearity without requiring more precise op amps.
These DACs include an internal deglitching circuit that
reduces the glitch impulse by more than ten times to less
than 1nV-s typ.
The DACs have a clear input and a power-on reset. The
LTC1595 and LTC1596 reset to zero-scale. The LTC1596-1
is a version of the LTC1596 that resets to mid-scale.
