描述

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 16-pin PDIP and SO wide packages. Both are specified over the industrial temperature range. Sensitivity of INL to op amp V_OS 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 midscale.
