LTC1595/LTC1596/LTC1596-1

Serial 16-Bit

Multiplying DACs

DESCRIPTION

The LTC®1595/LTC1596/LTC1596-1 are serial input, 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.
