The LTC1595 is pin and hardware patible with the 12-bit DAC8043 and es in 8-pin PDIP and SO packages. The LTC1596 is pin and hardware patible with the 12-bit DAC8143/AD7543 and es 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 pared 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 1n V-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.
